## Description

Bonuci 4 Pcs 1/4" Male NPT Safety Valve Air Compressor Pressure Relief Brass Safety Check Valve (125 psi Set Pressure)

## 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 is 125PSI, the flow is 49 scfm, and the temperature range is from 32 degrees Fahrenheit to 176 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

*by B***E on March 17, 2025*

These pressure releaf valves are installed in air pressure taks and seem to be working well. No air leaks anfter installing with sealant. Good value.

### ⭐⭐⭐⭐⭐ Great replacement part
*by A***9 on June 11, 2025*

Of course the one time I need to use my air compressor boom the valve goes bad. So far these have worked great and I am so glad it is a 3 pack so I will not have to order any for awhile
