Can any one give me a crossover for a dual low pressure switch for a MN PEH063KAP26R
SERIAL 5R03O11 Penn does not make it for Mquay any more they could not give me a
a replacement part # brand does not matter just need a switch that will do the same thing .

just buy a generic manual reset lp switch. get it in the pressure you want or an adjustable one. before installing it check actual trip points by hooking up to nitrogen.

We have had good luck using the Allen Bradlley 836 pressure controls.
