Product Changes
Swagelok has earned a reputation for unmatched quality and consistency at the component level. We are committed to maintaining this reputation while continuing to grow and improve our product offering. At times, this requires changes to the form, fit or function of our core products.
A Level 1 - Notification of Change sets forth changes to one or more of the products you may have purchased from Swagelok or an authorized Swagelok sales and service center. Prior to release, each change listed is carefully evaluated in accordance with the Swagelok Quality System, to minimize impact to our end customers.
A Level 1 Notification relates to an applicable* change impacting Form, Fit and/or Function ("FFF") or the cosmetic appearance of a standard product. "Standard product" is any product that does not include a customer specified product or process attribute and can be purchased by any customer. This includes off-catalog product that can be assembled through designators, assemble to order ("ATO"), make to order ("MTO"), product produced by other means.
Unless otherwise noted, all changes are rolling changes and will take some time to flow through our global inventory. If you have questions regarding the impact of these changes on your applications, please contact your local authorized Swagelok sales and service center representative. They, along with regional technology centers, and trained field engineers, are available to assist you.
The following Level 1 Changes and other availability changes have been communicated in 2025 and 2026.
Change Effective Date: February 19, 2026Product Name: Krohne VAF-M1, Swagelok Branded Product
The Swagelok branded VAF-M1 flow meter with the FM Approval option has been discontinued. The Swagelok branded VAF-M1 itself will continue to be available with all other options listed in the catalog. If a customer requires the FM Approval option for an M1 flow meter, the Krohne branded version with FM Approval will continue to be available.
To reflect this change, the Variable Area Flow Meters catalog, MS-02-346, will be updated and the FM Approval option removed. The discontinued catalog option is designated with a “-B” at the end of the part number sequence.

SGRD, SGBD, SHRD, and SHBD series: thread size and type are marked on top of the dome
SGRA and SGBA series: thread size and type, maximum pressure rating, and ratio are marked on top of the dome
All series: bulk text is marked on the side of the regulator body
Moving forward, all markings will be:
All dome-load regulators, including ratio and DP variants: thread size and type, and maximum pressure rating will be marked on top of the dome; bias pressure (SGRD with DP option) or the ratio (SGRA and SGBA) will be included in the bulk text on the body
Change Effective Date: January 19, 2026
Product Name: Process Improvement Update: FM 4, 6 & 8 Hose Assemblies
As part of Swagelok’s ongoing commitment to process improvement, changes have been implemented to the FM 4, 6, and 8 hose assemblies. These specific assemblies will transition from the legacy Capweld design to the updated Uniweld design as Capweld is depleted. The update enables Swagelok to streamline supply chains and routing processes, resulting in improved lead times through market cycles.
There are no changes to the assembled hose’s ratings, overall hose length, or part numbers. To account for the change in the A‑dimension shown below, the live length within the assembly will be adjusted so the overall hose length remains constant.
To support this change, the relevant catalog (MS-01-180) has been revised to reflect the updated end connection length.
Change Effective Date: January 8, 2026
We’re pleased to announce a minor physical change to our Bolted Plastic Clamp Twin Support Kits that provides significant functional improvement as part of our continuous improvement efforts. The updated design features a mechanism that prevents plate rotation during assembly, thereby enhancing installation efficiency and reliability. Furthermore, this improvement increases resistance to rotation during operations, especially under vibration—resulting in greater stability, reliability, and product longevity. This will be a phased implementation; the new style will begin shipping on December 1, 2025, and you may receive both old and new designs until the remaining inventory of the previous version is fully depleted.
Change Effective Date: December 16, 2025
Product Name: 6-Moly Nuts: Transition to Hex Bar Manufacturing
To improve production efficiency, we are transitioning all 6-moly nuts from being machined out of round bar to being manufactured from hex bar stock. This change will not affect product dimensions or performance.
After the date of this notice, any future orders of 6-moly nuts may contain both styles and you may receive both styles until inventory is depleted. During the transition period, nuts may vary in appearance, as both styles will be in circulation. The depletion date for existing milled inventory is still to be determined.
Change Effective Date: January 1, 2026
Product Name: Transition-to-Laser-Marking-for-Swagelok®-Tank-Blanketing-Regulators
As of January 1, 2026, we will be transitioning from using labels to laser marking on the TBR and TBV size 4 and 8 regulator bodies.
Currently, the body is laser marked with the flow arrow and flow direction, while regulator details such as model, size, and pressure range are applied via a label. Moving forward, these details will be permanently laser marked to streamline the manufacturing process. This will be an inline change, and no action is required related to existing inventory in the channel.
Change Effective Date: January 1, 2026
Product Name: Lubricant Standardization for 83 and H83 Series Ball Valve End Screws
As of January 1, 2026, 83 and H83 Series end screws will be coated with molybdenum disulfide and graphite-based lubricant on the face of the end screw, in addition to the threads. This will replace the use of fluorinated-based wetted lubricant on this surface of the end screws. The inventory of traditional end screws will be phased out as inventory levels decline, with all products transitioning to the molybdenum disulfide and graphite-based lubricant by early 2026. Both catalogs (MS-01-166 and MS-02-357) are being updated to reflect the use of molybdenum disulfide and graphite-based lubricant for both wetted and non-wetted surfaces. This change is being made to improve the assembly process and overall quality of 83 Series ball valves.
Change Effective Date: July 1, 2026
Product Name: Handle-Insert-Material-Change-for-Swagelok®-43-Series-Valves-(Excluding-43G)
For all traditional 43 series valves, (excluding 43G), the handle insert material will be changed from brass to powdered 300 series stainless steel. Materials of construction will be updated in catalog MS-02-331. Valve geometry will remain unchanged, and no dimensional or functional alterations will occur.
Change Effective Date: November 25, 2025
Product Name: Swagelok® PGI Design Change
The marking on the 2-1/2” safety glass window has been updated from “Safety Glass” to the following:
From the U.S., the designation now reads “LSG”.
From the EU, the designation now reads “LSG-C”.
LSG stands for “Laminated Safety Glass.” This change is designed to enhance the clarity of the dial reading by eliminating any visual interference caused by the previous marking.
Why this matters:
Improved reliability: The new marking ensures that the dial remains unobstructed, allowing for quicker and more accurate readings
Performance: This update does not affect the fit, form, or function of the product. All technical specifications and performance standards remain unchanged
Wika’s existing products remain fully compliant and operational. Future shipments will include the updated marking as part of their standard manufacturing process.
Change Effective Date: September 23, 2025
Product Name: Enhanced Temperature Rating for ALD20
As part of our ongoing commitment to supporting Swagelok’s semiconductor market strategy of leading with technology, we’re excited to announce an important enhancement to our ALD20 product capabilities. We’ve expanded the maximum body and actuator temperature ratings from 392°F (200°C) to 482°F (250°C). This update applies to both operating and immersion temperature ratings.
It’s important to emphasize that no changes have been made to the ALD20 product’s design, bill of materials (BOM), or assembly process that would affect its fit or form in any way to achieve this increase in function. Through rigorous and comprehensive testing, we have validated the product’s performance at the higher temperature threshold.
To support this update, the relevant catalog (MS-02-301: Updated in September Product Portal/eDTR refresh) and technical bulletin (MS-06-123: Update in progress) have been revised to reflect the enhanced temperature ratings.
This advancement not only strengthens our product offering but also positions Swagelok to better support innovation and growth in the evolving semiconductor market—helping us maintain our competitive edge and capture new opportunities.
Change Effective Date: September 2, 2025
Product Name: Phenolic Handle Changes for Swagelok® Needle Valves
Description of Change: Swagelok will be implementing changes to our needle valve phenolic handles and their associated kits. These changes are being implemented in response to current supply chain risks and should help ensure the long-term health of our supply chain and product availability. There is no change to the phenolic handle material.
This change will include some small visual improvements (see images below) and slight changes to color. There will be minor dimensional changes to the handles that impact height; however, assembled, open valve height will remain within +/- 0.02 inches (0.508 mm) of current height. This will be a rolling change, and you will notice either design within orders.
This change will affect the following valve series: O, 1, 18, 20, 26, 31
Change Effective Date: September 2, 2025
Product Name: Colored 83 Series Phenolic Handles
Description of Change: Swagelok will be implementing changes to our colored phenolic 83 series handles. This change is being implemented in response to current supply chain risks and should help ensure the long-term health of our supply chain and product availability. There is no change to the phenolic handle material.
The logo will change from the Whitey logo to a Swagelok logo
The new handles will be available starting on September 2. Product will transition over time so both handle styles may be seen in shipments until current inventory is depleted.
Change Effective Date: May 1, 2026
Product Name: 2D (Two-Dimensional) Barcodes Added to B Series Bellows Valves
Description of Change: One of the ways Swagelok lives its core value of quality is to implement technologies that help enhance product quality. Establishing a unique identification number for each valve body and applying a 2D barcode to the product allows the product’s progress to be tracked through assembly operations. This unique ID also links the valve to a rigid verification process to ensure the valve’s assembly to factory specifications.
Starting in 2012, we began applying 2D barcodes to select high purity products.
B Series Bellows Valves: Effective May 1, 2026, 2D barcodes will be applied to B Series bellows valves.
Product will transition over time, so both marking styles may be seen in shipments until the current inventory is depleted.
We continue to investigate adding a 2D barcode to other products and expect to implement it on more products in the coming months.
Important: Although 2D barcodes are similar in appearance to QR (Quick Response) codes used in various media, the underlying code language is different. Specific equipment is needed to read the 2D barcode.
Change Effective Date: July 10, 2025
Product Name: Dielectric Fitting Warning Label Change
Description of Change: Swagelok® Dielectric Fittings will no longer be supplied with a sticker, effective immediately. Instead, the part will be laser engraved with the same statement, "DO NOT WRENCH THIS HEX NOR DISASSEMBLE THIS CONNECTION!" will remain unchanged. This change is part of our ongoing efforts to streamline production and enhance supply chain efficiency. There will be no impact to product performance or functionality due to this change.
Effective Date: May 2025
Product Name: C Series Check Valve Catalog Changes
Description and Reason for Change:
Reseal pressures for Swagelok® C series check valves has been updated to reflect an increase as shown:
Change #2:
The low-temperature limit for the CH series check valve with standard fluorocarbon FKM seals is being changed from -10ºF (-23ºC) to +10ºF (-12ºC). This change will not impact the ratings of products or kits sold prior to the effective change date of August 1, 2025.
If you require a lower temperature rating, please reference the additional seal material options on page 14 of the catalog (MS-01-176).

Product Name: SWS-M200 Pressure Transducer Change
Description and Reason for Change:
Product Name: Select Fine Thread Flare Fittings
Description and Reason for Change:
We expect to be able to fulfill all orders that are placed before the change effective date. Please consider ordering more prior to September 17th should you need them in the near future. Swagelok offers PFA alternatives for many of the fitting part numbers and alternatives are available for some of the fittings. For valves, all impacted part numbers will transition to receive PFA nuts beginning on September 17 at the earliest. Please contact your account manager or monet.williams@swagelok.com for a list of affected part numbers.
Product Name: Design Changes Regarding SAE/MS Straight Thread (ST) Ends
Description and Reason for Change:
Shoulders are used on ST fittings when the hex size is notably larger than the ST male connection size. The shoulder reduces the connection area and provides clearance between the larger hex and the mating surface of the female ST, allowing for proper sealing. The shoulder will also facilitate the installation process as it better shows the metal-to-metal contact per SCS-00634 (Installation Instructions of Swagelok Fittings). It will not affect the product's rating.
This design change will take effect March 1, 2026. Products manufactured after March 1, 2026, will feature a turned shoulder and extended length as designated above. Customers must prepare to receive this slightly different design as of March 2026. After this date, customers may receive products with and without this turned shoulder and increased length, as inventory is depleted.
Product Name: Lubricant Change for CPA Series Check Valves and F Series Filters
Description and Reason for Change:
Swagelok has transitioned to an alternative molybdenum disulfide-based lubricant on the threads of our CPA check valves and F series filters. This dry lubricant is applied to wetted threads on these products and may be subject to system media exposure. This change will ensure the availability of these products for Swagelok customers.
Please contact your Swagelok Southern California account manager to review potential impact on your applications and corresponding requirements.
Effective Date: February 13, 2025
Product Name: Select Hose Cutter and Tube Cutter Obsolescence
Description and Reason for Change:
Due to supplier discontinuation, MS-HC-SC-A is no longer available, effective immediately. An alternative offering exists and should be ordered in place of the obsoleted part number.
