Kwang Woon 1/2" Stainless Steel Water Hammer Arrestor WHB Series

A water hammer arrestor is a pre-charged stainless steel shock absorber with 1/2" male IPS thread that eliminates pipe banging and protects plumbing systems from pressure surges caused by quick-closing valves, preventing damage to pipes, fittings, and appliances. This Kwang Woon WHB Series arrestor features stainless steel bellows construction rated up to 350 PSI and 250°F (121°C), designed for UAE's domestic and commercial plumbing installations across Dubai and the Emirates where reliable water hammer protection and maintenance-free operation are essential.

What is water hammer and why do I need an arrestor in the UAE?

Water hammer is the loud banging noise and pressure surge that occurs when a valve closes quickly in a plumbing system—common with washing machines, dishwashers, solenoid valves, and quick-closing fixtures. When flowing water suddenly stops, its momentum creates a shock wave that travels through pipes at the speed of sound, causing that familiar banging sound. Over time, these repeated pressure spikes damage pipes, loosen fittings, stress joints, and shorten the life of appliances and fixtures. A water hammer arrestor absorbs these pressure surges using a stainless steel bellows and pre-charged air chamber that cushions the shock instantly. In UAE's residential and commercial buildings across Dubai, water hammer arrestors are essential protection that eliminates noise, prevents damage, and extends plumbing system life.
