Water hammer arrestor with 1/2 inch BSP male connection.
Water hammer occurs when a device (such as a tap or valve) is suddenly closed, creating harmful over pressure. In domestic plumbing this is experienced as a loud banging, resembling a hammering noise.
This device incorporates a steel spring and plastic disc with double o-ring seal, which opposes much of the excess pressure.
