General Pump Piston Oil Seal Kit | Interpump Oil Seal

Pressure washer pumps require proper lubrication for optimum performance. To prohibit water from mixing with the oil in the pump crankcase, General Pumps are manufactured with a piston oil seal, found on the pump piston, just behind the ceramic plunger sleeve. We recommend inspection of the plunger oil seals whenever replacing high pressure and low pressure pump seals.
