Brass PEX Cap: Leakproof ASTM F1807 Sealing for Water & Heating

Brass Pex Cap Leakproof Performance Advantages

Our crimp-style brass pex cap complies ASTM F1807 standards to permanently seal PEX pipe dead ends for domestic water and underfloor heating systems. Integrated EPDM inner ring cuts pipeline leakage rate to 0.3%; complete 12–32mm size range matches residential and commercial manifold piping projects across all climate zones.

Case Study

Zambia Rural Domestic Water Pipeline Retrofit Project

A Lusaka water engineering firm ordered 70,000 FOSTE brass pex caps for community PEX water manifold dead-end sealing. Uniform crimp fit eliminated hidden water seepage, helping the whole piping system pass municipal pressure inspection on the first submission without extra repair labor cycles.

Eastern Europe Apartment Radiant Heating Batch Project

A Hungarian construction contractor sourced 92,000 pex caps for multi-unit underfloor heating manifold terminals. Anti-oxidation forged brass resists long-term indoor humid environments, slashing annual heating pipeline maintenance costs for property management teams by 64%.

Puerto Rico Commercial Plumbing Renovation Wholesale Supply

A Puerto Rico plumbing wholesaler purchased 51,000 matching pex caps bundled with bulk FOSTE PEX tubing. Precision machined body avoids cracking during crimping work, lowering accessory replacement expenditure for local plumbing subcontract crews by 67%.

FOSTE (Shijiazhuang Shentong Plastic) manufactures full-size brass pex caps perfectly matched with our PEX-A, PERT and composite tubing series, supported by over 30 years professional plastic pipeline manufacturing experience. Each pex cap adopts high-purity forged brass with integrated EPDM sealing rings, stable under 8bar working pressure and 95°C hot water temperature, fully passing ASTM and CE industry certification. We support OEM logo stamping and one-stop bundled supply of PEX pipes, crimp tools and all supporting fittings for global plumbing distributors and construction contractors.

Integrated EPDM Ring Dual Sealing Design

Built-in elastic EPDM sealing ring creates tight compression after crimping, blocking water seepage caused by PEX pipe thermal expansion and contraction. Accelerated lab cycle testing confirms zero leakage after 10,000 heating-cooling temperature fluctuation cycles.

Anti-Corrosion Forged Brass Raw Material

High-density forged brass with anti-oxidation surface treatment avoids rust in humid indoor and mild coastal installation environments, extending manifold pipeline service life to over 50 years without frequent cap replacement work.
