Description
Adjustable air regulator assembly for air compressor units that have a 4-port pressure switch. 1/4" FPT inlet/outlet, 1/8" FPT port for pressure gauge (to maximize performance, we recommend including this compatible pressure gauge for your regulator).
If air leaks from the regulator, or when you turn the knob it doesn't adjust the PSI up or down, replace this part.
