Two brass safety valves, 1/4 inch NPT, 125 PSI, 40mm long with pull rings

2-Pack 1/4" NPT 125 PSI Brass Safety Valve

SKU CH-V0VJ-4R9NZ

Two brass safety valves with 1/4" NPT threads relieve pressure at 125 PSI for air, water, diesel or oil systems

  • Two valves per pack ready for immediate spares
  • 125 PSI rating matches common compressor tanks
  • Brass construction resists corrosion in wet air lines
  • 1/4" NPT threads fit standard ports without adapters
  • Automatic relief prevents over-pressure damage to equipment

Safety Valve Pair

This two-pack supplies 1/4-inch NPT brass safety valves rated to 125 PSI for air compressor systems. Each valve uses a copper body to resist corrosion and handle water, air, diesel fuel or oil. The automatic one-way design opens when tank pressure exceeds the preset limit and reseats once pressure drops back to the reset point. They install vertically or horizontally in automotive, industrial or power-equipment plumbing.

Who This Suits

Mechanics and maintenance teams needing spare or replacement pressure-relief valves for 1/4-inch NPT ports at 125 PSI will find the pair convenient. The valves are not suited for high-temperature environments, so operators running hot-fluid circuits should look elsewhere. Buyers who require a different thread size, a higher pressure setting or a non-brass body will need another product.

Build Integration

Each valve measures 40 mm overall with a 13 mm centre diameter and 33 mm length without the pull ring, fitting tight compressor manifolds. The 1/4-inch NPT male thread connects directly to standard tank or line fittings without adapters. Brass construction frees the installer from adding separate corrosion protection, and the one-way action prevents backflow that could damage upstream components.

Highlights

  • 125 PSI rating matches common compressor tanks
  • Brass construction resists corrosion in wet air lines
  • 1/4" NPT threads fit standard ports without adapters

Questions about this item

What thread size must my compressor tank or fitting have for the 1/4" NPT male connection?

The valve has a 1/4" NPT male thread, so the mating port must be a 1/4" NPT female opening.

Will the 125 PSI relief setting protect a system that runs at lower pressure?

Yes, the valve opens only when pressure exceeds 125 PSI, so it will not vent during normal lower-pressure operation.

How can I confirm the valve is seated and not leaking after installation?

Pressurise the system to working pressure below 125 PSI and check the 13 mm centre area for escaping air or fluid; no leak means it is seated.
