1/2" Press-Fit Connection Washing Machine Drain Box with Brass Water Hammer Arrestor

This product is a high-performance integrated solution specifically designed for modern home laundry rooms, ingeniously combining a brass water hammer arrestor with a press-fit pipe connection. It balances installation efficiency, safety protection, and long-term durability.

The main body utilizes high-strength corrosion-resistant engineering plastic, housing a solid brass forged water hammer damping module at its core. Through a precision-engineered nitrogen-precharged chamber and food-grade diaphragm, it instantly absorbs the intense water hammer shock waves generated during washing machine start-stop cycles. This efficiently eliminates pipe noise and vibration, safeguarding valves, fittings, and the washing machine itself from pressure damage, thereby extending equipment lifespan.

The patented compression-fit interface accommodates rigid pipes like stainless steel and PEX. Installation requires only specialized crimping tools—a single press achieves sealing strength surpassing traditional threads, eliminating leakage risks while significantly reducing construction time and labor costs. The housing integrates hot/cold water angle valve connections, a large drain outlet, and electrical wiring ports. All functional units are thoughtfully arranged to conceal piping, maintain tidy spaces, and enhance both aesthetics and safety in laundry areas.

Ideal for residential homes, apartments, commercial laundromats, and similar settings, it particularly suits users prioritizing installation efficiency, long-term stability, and an exceptionally quiet experience.

Core Advantages:
Dual Protection: Brass water hammer arrestor + crimp seal provide double safeguards against water hammer and leaks;
Installation in Seconds: Crimp fittings eliminate welding/threading—one press locks it in place, saving time and effort;
Long-Lasting Corrosion Resistance: Brass body resists chlorine and rust, compatible with diverse water qualities, outlasting standard fittings;
