Craftsman Replacement Pressure Switch with Safety Relief Valve

Brand new LEFOO 95-125 PSI air compressor pressure switch control valve with a single female NPT air inlet connection port, paired with a 1/4" FNPT brass tee, two 1/4" MNPT pipe nipples, and a 1/4" NPT 135 PSI safety relief valve. This setup is used to replace the pressure switch on older Craftsman compressors where the relief valve is built directly into the mount on the pressure switch. A common Craftsman compressor that uses this setup is model #919.165310 

This switch is equipped with an unloader valve, on / off lever, and a single female NPT air inlet port. The unloader equipped on this switch is used to unload the air pressure off the head of the compressor when the compressor shuts off, this way when it starts there is no pressure on the piston and the compressor can start load free. This valve usually has a 1/4" plastic or copper line that runs to the check valve or the head of the compressor. If your compressor does not have an unloader line, then this valve can be left not hooked up and the pressure switch will still function properly.

This switch comes preset to turn the compressor on at 95 psi and shut off at 125 psi. This can be adjusted to any pressure within the factory minimum and maximum set points listed below.
