Review: Worked great - Worked great

## Features

- Package Includes: you will receive 4 pieces of 1/4 inch NPT threaded pressure relief valve with seal thread locks, enough quantity for your daily use and replacement, providing more convenience for you
- 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
- Product Information: the working pressure of safety release valve is 150PSI, the flow is 178 cfm, and the temperature range is from -65 degrees Fahrenheit to +250 degrees Fahrenheit
- Warm Tips: the 1/4 inch brass air pressure release valve for using in high temperature applications up to 250 degrees Fahrenheit, please pay attention to safety when using
- Practical Function: 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; 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
