I used a FORD master cylinder gasket number 42098. It is the right overall diameter and I used a hole punch, slightly oiled, in my drill press to put in the four screw holes. The hardest thing is getting the nuts back on the screws to hold the switch together. But it works for $5.

My Central Pneumatic (mdl 94667) is limiting its output to about 50 psi and below. I am able to adjust it lower but it will not go any higher. The tank pressure is always well over a 100psi. Any...

It sounds like the regulator you use to adjust the hose pressure is not working properly. Sometimes they can be affected if dirt or rust particles get into the regulator. You might be able to disassemble and clean it although some regulators are quite complex and require knowledge and insight in regulator repair to perform. It may also be the regulator is defective or worn out and needs to be replaced. Given the cost of the relatively low cost of the compressor it was likely not a very high quality regulator to start with and needs to be replaced.

My Central Pneumatic model 42321 has a torn diaphragm under the on/off switch. Can I get this part anywhere, or barring that a new pressure switch assembly?

To fix the diaphragm gasket in my Dad's air compressor model # 42321, my brilliant bofriend went to the auto parts store bought a master cylinder gasket for a Ford, model # 42098. He had to punch 4 holes in the new gasket for the screws. He trimmed the excess off after it was tighten. It works like a charm and only cost $5.00. Hope this helps.
