Our UPVC male thread adapters with stainless steel insert offer the highest mechanical strength and thread endurance for high-stress connections to pumps, gauges, and metal fixtures. By utilizing advanced insert-molding technology in our factory, we permanently embed a premium Stainless Steel (SS304/SS316) core within the UPVC body, ensuring the fitting resists heavy wrench tightening torque without deformation, cross-threading, or material failure.
Stainless Steel Insert Durability: High-grade SS insert provides long-lasting, repeatable thread engagement for wall-mounted taps and high-pressure pumps.
Thread Transition Port: Precision internal threads allow deep, secure engagement with male pipe threads and instrument fittings.
Leak-Proof Jointing: Engineered with specialized anchor grooves that lock the SS core, eliminating rotation or water seepage.
Strict Factory QC: Each production batch is tested in our factory laboratory to guarantee zero leakage at the plastic-to-metal interface under high pressure.
