Valve
Part #D20114
This safety valve is a genuine replacement part manufactured for use with air compressors. If the compressor's pressure switch malfunctions, and does not turn the motor off when the amount of pressure is met, the safety valve will open to release the extra air pressure. The amount of pressure required to open the safety valve is set by tension of the spring inside the valve. The spring can wear out, and leave the valve open at a lower pressure than what is set to turn the switch off, and will not allow pressure to build inside the tank. This safety valve has a thread sealant pre-applied, so additional thread sealant is not required, the safety valve is sold individually.

Disassemble plastic housing around compressor unit using appropriate tools. Remove the four bolts from the compressor head using a 5/16 nut driver. Carefully remove head assembly including airline. Remove bolt through rod bearing with Allen wrench.

Reassemble with new rod and piston assembly. Best to use blue locktite on bolt through rod bearing when reassembling. Make sure to torque all bolts to specs listed.

Can't find this special screw used on many housings etc

Actually don't like using Torx bits because they are hard to center deep in the channel. I had misplaced these forcing me to order replacements.
My plan is to insert Torx bits before screwing in and using jb weld to secure the bit to the screw, giving me a hex head. Can't find this special screw with a hex head. This screw is called AGC-408 by craftsman.
