4126 Crankcase Pressure Sensing Valve

SKU 4126

AMOT Model 4126 detects the minor pressure surge that usually precedes a major crankcase explosion. It will detect the smallest pressure buildup caused by worn packing or by excessive blow-by caused by a piston and liner just beginning to scuff. This high sensitivity provides instant warning or shutdown before major damage occurs as the unit will not reset itself automatically.
