A brass pressure relief valve with 1/4" MPT inlet. This is a safety device on the pressure washer. When a pre-determined pressure is reached within the system, the valve opens and releases water into the atmosphere, or back into the line.
Pop-off valves are used as a backup to your regulator or unloader. They are designed to protect your pump if the regulator or unloader fails. All models features machined brass construction with stainless steel internals. Specifications:
