Conrader NG-5-M-140-175 Air Compressor Pilot Check Valve Combo – 140 To 175 PSI Unloader

This Conrader valve combo is the brain behind your gas air compressor’s start-stop cycle.

It’s a piloted unloader valve with a built-in check valve, all in one unit, set to kick in between 140 and 175 PSI.

Made in the USA, it’s got that solid build quality you want for heavy-duty gear.

There’s even a handy 1/8-inch port on the side if you need to hook up a throttle control or cable.

If your compressor’s acting up or you’re doing a rebuild, swapping in this NG-5-M-140-175 cleans up the plumbing and gets things running smooth again.

Quick note: California folks, it has the Prop 65 warning, so just be aware.
