Brass PEX adapters are the essential transition fittings that let you connect PEX tubing to copper pipe, threaded valves, or existing plumbing fixtures with confidence. Whether you’re tying into an old copper stub-out, connecting to a threaded shut-off valve, or adapting PEX to a water heater nipple, these versatile fittings bridge the gap between modern PEX systems and traditional plumbing materials. Our complete range includes female sweat adapters for soldering to copper pipe, male and female threaded adapters (MNPT/FNPT) for valve and appliance connections, and specialty configurations for mixing materials without compromising system integrity. Every adapter is designed to create leak-free transitions that hold up under pressure in both residential and commercial installations.
Manufactured in the USA from lead-free ECO BRASS® alloy, these adapters deliver the strength, temperature tolerance, and corrosion resistance that plastic transition fittings can’t match. The high-performance brass construction provides strong, reliable threads that won’t strip under torque, while the material’s inherent antimicrobial properties offer added protection in potable water systems. Each fitting meets NSF/ANSI 61 compliance standards and ASTM F1807 specifications for crimp connections, with pressure and temperature ratings that handle both hot and cold water applications up to 180°F and 190 psi. Compatible with PEX-A, PEX-B, and PEX-C tubing, these adapters work with standard crimp and expansion tools, and threaded ends seal quickly with PTFE tape for professional installations that pass inspection the first time.
Stock your truck or supply warehouse with our contractor-friendly bulk packaging. Our brass PEX adapters give you the inventory variety to handle unexpected transitions without making emergency supply runs. Brass won’t degrade, flake, or lose integrity under pressure like plastic alternatives—delivering the leak-free performance that keeps your reputation solid and your projects on schedule.
