Safety Valve Set for Air Systems

The VIAIR 92175 is a set of safety valves rated at 175 PSI. Each valve uses a 1/4-inch male NPT thread and is designed for high-temperature operation. It protects compressors and pneumatic circuits in 12- and 24-volt automotive applications.

Replaces Worn or Missing Relief Valves

Install this set when an existing relief valve leaks, fails to open at pressure or has been removed during service. The 175 PSI rating matches many VIAIR compressor specifications, so the swap restores the original pressure limit without altering system behaviour.

Suits 12-Volt and 24-Volt Mobile Pneumatic Builds

Builders running VIAIR compressors on off-road or suspension systems will find the correct thread and pressure rating here. Shops working on industrial stationary tanks or low-pressure airbrush lines should look elsewhere because the rating and thread differ.

Questions about this item

What thread size does the 175 PSI safety valve use for mounting?

The valve has a 1/4-inch male NPT thread for direct installation into a compatible port.

How should the safety valve be installed to ensure it functions correctly?

Thread the valve into the 1/4 NPT port by hand, then tighten with a wrench on the hex flats without over-torquing the brass body.

When should the 175 PSI safety valve be replaced?

Replace the valve if it releases air below the 175 PSI rating, fails to vent at pressure, or shows corrosion on the 1/4 NPT threads.
