Pressure Washer O-Rings for Quick Disconnect Hose Fittings

3/8" Quick Disconnect O-Rings for hot water and steam up to 400°F (204°C). Replacing the O-Rings in a pressure washer nozzle since rubber O-Rings eventually deteriorate. We offer many compounds to meet your specific needs. Changing your O-Rings in a timely manner saves you the continual messy water leaks, loss of maximum water pressure, and unnecessary water use and costs.

EPDM compound for ozone, water & UV service. Sulfur-Cured EPDM is the least costly and provides the best Tear and Abrasion Resistance compared to Peroxide-Cured Systems.  EPDM Compounds are frequently used with foods, water, steam applications, phosphate ester type hydraulic fluids, brake fluids and offer the best resistance to ozone and weathering.  EPDM's are not used with petroleum oils or fuels because significant swelling would result.
