High-Pressure Resistant Structure: Say goodbye to impurities damaging your plunger!   Our power washer pump strengthens plunger hardness to improve wear resistance and prolong the life of water/oil seals.   The one-piece pump head made of forged brass material offers a better sealing effect, high strength, and increased durability.
Easy Oil Level Inspection: Checking the oil level has never been easier with our replacement power washer pump's sight glass and advanced oil seal technology – no need to use an oil dipstick.   With visibility to the oil level and the oil itself, you can easily see when oil levels are low or if water has clouded the oil.
