Product Description

By entering your model number, you can make sure that this fits.

The relief pressure is set to 120 psi, and the flow rate is set to 47 SCFM.

IMPORTANT INFORMATION: 1/4" MALE NPT THREADED INLET CONNECTION APPROX 0. OUTSIDE DIAMETER: 54 INCHES

For corrosion resistance, the spring is made of stainless steel and is made of brass. A silicon O-ring provides a leak-proof seal to within /- 10% of the relief pressure, and the preset relief pressure is accurate to within /- 3%.

For use in high-temperature applications, the maximum temperature is 250 degrees Fahrenheit.

Questions & Answers

What country does it come from?

It's most likely on the moon or in China.

If the pressure rises above 60 psi, will it release?

No, it won't release until 120 psi has been reached.

Will it fit a husky air compressor model h1504st2 with a 4 gallon tank and a 1.25 gallon capacity? 5 hp?

The thread on the majority of these relief pressure valves is the same; all you need to know is your compressor's maximum pressure, which should be around 150 psi. Over your compressor, set the pressure to 20 psi.

Selected User Reviews For New 1/4" NPT 120 PSI 47 SCFM Air Compressor Relief Pressure Safety Valve, Tank Pop Off

My problem was not resolved! This new safety switch was installed, but it didn't solve the problem

3/5

Before it got close to 150psi, it would pop off! After installing the new safety switch, I changed the pressure switch, but the problem still exists. I'll get a refund if I send it back. I'm guessing the seller isn't going to replace it with a brand new one. Thank you, Amazon, for reimbursing my funds!.

It was exactly what the doctor had prescribed

5/5

My compressor continued to leak, and the pressure eventually returned to normal. Just as the normal tank pressure was approaching, the leaf valve would pop. My slow leak was fixed after I replaced it with this one (which is rated the same as the old one).

It works

5/5

The factory relief valve on my air compressor began to leak. It was no longer able to seal properly and would pop open unexpectedly. The issues vanished after I replaced it with this model, and I am once again a happy camper.

The pressure switch and the relief valve were both replaced

5/5

The old pressure switch had to be replaced because it wasn't working properly. A pressure relief valve was also replaced. Saving money on a new compressor was a short-term fix.

As expected, it functions properly

5/5

Good price, quick delivery, and compatible with my gas powdered compressor. Because the unloader is defective, it frequently reaches maximum pressure, so I replaced the old, leaking relief valve to ensure safety.
