Suits 85 PSI activation need

This part suits installers who need a switch that closes at 85 PSI. It is not for systems requiring a different cut-in pressure. Buyers who need a different port thread size should look at other options.

Activation pressure 85 PSI

The single specification that decides fit is the 85 PSI On setting. Verify that your compressor requires this exact activation pressure before purchase. The 1/8 inch M NPT port and 1/4 inch spade connectors must also match your plumbing and wiring.
