Pressure Regulator Knob Replacement
Sanborn compressor regulator parts
I have (I believe) a Sanborn BlackMax AL of 3.5 HP. Have not used it in a while. Went to use it and got no hose pressure. Noticed that the knob and spring were laying on the floor. Apparently knob broke loose. Looking for a replaced to these parts and do not know where to find them or part numbers. I have included several photos of these items. Any help is greatly appreciated.
