The ASTM Standard UPVC Female Thread Adaptor facilitates a secure transition from solvent-weld plastic pipe ends to male-threaded valves, equipment, or metal fixtures. Featuring precision-molded female threads, this adapter offers a reliable transition between plastic piping networks and threaded mechanical components.
Technical & Design Advantages:
Precision-Molded Threads: Sharp, clean-cut NPT/BSPT threads ensure deep engagement and a tight, leak-proof seal with standard thread sealant or PTFE tape.
Heavy Outer Collar Reinforcement: Molded with a thickened external reinforcement band around the threaded socket to resist radial stress and prevent splitting during wrench tightening.
Non-Conductive & Corrosion-Free: Completely non-metallic assembly eliminates galvanic corrosion and thread seizure common in metal transitions.
Applications:
Water meter and backflow preventer installations.
Connecting plastic pipes to brass, stainless steel, or bronze valves.
Pump suction and discharge line connections.
Residential faucet and appliance supply hookups.
