## Features

- 【Reliable and Sturdy】made of brass, the NPT threaded air compressor parts have corrosion resistance, high temperature ductility and low magnetic permeability, suitable for discharging air, water and oil from air compressor
- 【Practical Function 1】the air compressor pressure valve can reduce overpressure or vacuum in the system; When the pressure in the air compressor box exceeds a preset level, the valve opens, allowing fluid or gas to escape to reduce the pressure;
- 【Practical Function 2】When the pressure drops below the preset level, the valve opens, allowing fluid or gas to be released into the system, then closes when the valve reaches the reset pressure limit
