Therwen 4 Pcs Air Compressor Parts Replacement and Air Gauge Set, 1/4" Npt Relief Pressure Safety Valve 0-125 Psi Pressure Gauge for Tank Accessory(200 PSI)

I finally broke down and replaced the gauges on my air compressor. The old ones were damaged and the relief valve would open from time to time. I got the whole set in one package. The gauges seem to be accurate and easy to read. Made from heavy gauge brass and do not leak. Well pleased with the set and the price.

Gauge threads are 1/8, that is in the description, pretty vague. Everything else leads you to believe that all is 1/4 threads I just happen to have the 1/4 to 1/8 fittings without running to the store or returning them. That's what happens when going cheap.

Look professional,work great

Valves work fine but the gauges read nearly 10 psi low

These gauges and pressure safety valves work great. They appear to be high quality.I have an older Craftsman air compressor, and I originally ordered these as one of my gauges had stopped working and was leaking and I suspected that my safety valve was also leaking. So I ordered this kit expecting to have an extra gauge and safety valve... ENDS up, after replacing the first gauge I noticed that the main valve was also leaking. SHEESH! I had already taken a picture of the single gauge installed, so that's what I've added, but both are now in use.So I used both gauges and one safety valve and everything works great. No leaks and what appear to be good/accurate pressure readings.Install was straightforward. Just an 11mm wrench and some Teflon tape. The threads on the fittings were good clean quality. The gauges are easy to read.I am very happy with these parts.

Pressure relief valves were 1/4npt. The gages were not 1/4". Very deceptive listing. The gages were 1/8". Listing made it sound like all nipples were 1/4". Be careful and make sure these sizes will work for u.

Nice 4 pcs air kit, works great on my compressor gauges are accurate and pop off valves work just as they should.
