Seal the line. Test with confidence.
Secure your plumbing rough-in with the unyielding reliability of this Poly Alloy PEX Plug. Engineered from high-performance Modified Polyphenylsulfone (PPSU), this end cap provides a permanent, leak-proof seal that is corrosion-, mineral scale-, and electrolysis-resistant. Ideal for pressure testing new lines or permanently terminating unused branches, it meets rigorous ASTM F2159 and CSA B137.5 standards. Available in single units for quick repairs or 50-piece pro-packs for stocking your truck.
Features
- Advanced PPSU Construction: Molded from Modified Polyphenylsulfone, a high-tech polymer that offers the impact strength of metal without the risk of rust, corrosion, or dezincification.
- Electrolysis Immune: The non-conductive plastic material prevents galvanic corrosion, making it the perfect choice for capping off lines in mixed-metal systems.
- Pressure Test Ready: Designed to withstand high test pressures during rough-in inspections, ensuring your crimp connections are secure before drywall is installed.
- Code Compliant: Certified to NSF/ANSI 61 for potable water safety and meets cUPC and CSA B137.5 standards for use in Canada and the US.
- Universal Fit: Precision-molded barbs fit all standard PEX-B tubing and can be secured using copper crimp rings or stainless steel pinch clamps.
