Engineered for residential and commercial potable water plumbing, our Premium Brass PEX Female Adapters provide a highly dependable, leak-free transition from flexible PEX tubing to rigid male pipe threads. Manufactured to strict ASTM F1807 standards from high-grade lead-free brass, these transition fittings offer maximum mechanical strength, high corrosion resistance, and safe operation for domestic drinking water networks.

Featuring a precision-machined barbed end on one side and standard female National Pipe Taper (NPT) threads on the other, these adapters allow for direct connection to plumbing manifolds, faucets, pumps, shut-off valves, and threaded brass nipples. They are designed to work seamlessly with either copper crimp rings or stainless steel pinch clamps, ensuring a permanent connection that handles constant pressure changes and thermal expansion.

Key Features and Benefits

ASTM F1807 Standard Compliance: Precision-engineered to match universal mechanical dimensions for crimp-style PEX systems, ensuring perfect compatibility with all major brands of PEX-A, PEX-B, and PEX-C tubing.
Lead-Free Brass Construction: Forged from premium lead-free brass, meeting the strict requirements of NSF/ANSI 61 and NSF/ANSI 372 standards for safe, clean drinking water systems.
Precision-Cut Female NPT Threads: Features deep, clean American National Standard Taper Pipe Threads to ensure a tight, secure mechanical fit when receiving threaded valves, fixtures, or metallic pipe transitions.
Dual Connection System Compatibility: Highly versatile fitting design that can be secured using standard copper crimp rings with a traditional crimping tool, or stainless steel cinch clamps with a universal pincer tool.
Industrial-Grade Durability: Thick, resilient wall construction protects against dezincification, stress-corrosion cracking, and physical damage behind walls or buried under concrete slabs.
