And what does it do? My air compressor cannot get above 60 PSI, it should get to 120 psi. I noticed this piece is where I am losing pressure. Can I replace it?

It looks like it could be a cold start valve.

From Google: "An air compressor cold start valve bleeds air from the compressor head during the first few pump revolutions, reducing torque requirements for starting a motor. This helps the compressor start easier."
