Installation Method
Requires a PEX expansion tool and PEX-A expansion collars. Not compatible with crimp tools, copper crimp rings, or stainless steel pinch clamps.
- Slide the expansion ring over the end of the PEX-A tubing.
- Expand the tubing and ring simultaneously using a power or manual hand tool.
- Insert the stainless steel cold expansion PEX plug into the expanded tubing.
- Hold the fitting in place until the tubing and collar shrink back down to secure the connection.
Applications & System Integration
- Capping off unused PEX-A potable water lines.
- Terminating runs in radiant heating and hydronic systems.
- Commercial water distribution requires 304 stainless steel plumbing fittings.
- High-acidity well water systems are prone to fitting corrosion.
- Temporary line testing before fixture installation.
- Integration into ASTM F1960 cold expansion PEX systems using 304 stainless steel fittings.
Compliance & Certification
These ASTM F1960 PEX fittings meet NSF/ANSI 372 and NSF/ANSI 61 standards for lead-free potable water. They maintain full cUPC and CSA B137.5 compliance for safe, code-approved plumbing installations.

Frequently Asked Questions
What tools are needed for stainless steel cold expansion PEX plug installation?
You need a manual or battery-operated PEX expansion tool and compatible PEX-A expansion rings. Standard crimp tools will not work with cold expansion PEX fittings.
Can I reuse a stainless steel cold expansion PEX plug?
Yes. The plug can be reused if the PEX tubing and expansion ring are carefully removed without scoring or damaging the fitting barbs.
How do I remove a stainless steel cold expansion PEX plug without damage?
Apply gentle heat to soften the PEX tubing and expansion ring, then carefully cut the ring and tubing away with a utility knife. Avoid cutting into or scratching the stainless steel fitting.
Are these fittings compatible with PEX-B tubing?
No. These cold expansion fittings are designed exclusively for PEX-A tubing. PEX-B does not have the required memory characteristics for expansion connections.
Why choose a stainless steel PEX plug over brass?
304 stainless steel provides superior corrosion resistance and does not experience dezincification. It performs reliably in high-acidity or aggressive water conditions where brass fittings may degrade.
Are these NSF-certified PEX fittings safe for drinking water?
Yes. These fittings are certified to NSF/ANSI 61 and NSF/ANSI 372 standards and are approved for potable drinking water systems.
What is the maximum temperature this CE PEX plug can handle?
The 304 stainless steel fitting material can withstand temperatures up to 400°F (204°C). However, actual system operating limits are determined by the temperature rating of the installed PEX-A tubing.
