Easy repair
Order arrived on time and was exactly what I expected. It was easy to replace. Now my 10 year old compressor is not leaking air and running frequently when not in use. Hopefully, it will last another 10 yrs.

Easy Repair with this exact replacement Regulator
The regulator on my compressor had started leaking air through the adjustment shaft. So I found this replacement part. Received the part in 3 days after ordering and was able to make the repair quickly. Works great.

I installed part and it was defective. The air from the compressor would not even go through the ports to the gauge port.
