Pressure washer pump water Seals are a wear item in a pump because of the intense pressure they are subjected to. Karcher’s nested U-Seal technology holds up better.

The new technology of this U-Seal design, where the pump actually “nests” the seals of the pump’s high-pressure packing assembly in place, supporting the side walls, results in greatly increased seal life, allowing for extended time between seal replacement. The nesting assembly is stronger and holds up better to spikes in water pressure, which occur every time the gun is triggered.

THIS KIT DOES NOT INCLUDE BRASS PRESSURE RING OR BRASS INTERMEDIATE RING. If the brass pressure or intermediate rings show sign of damage or wear, please purchase a Complete Seal Kit.

Note: U Seals are NOT directly interchangeable with V Seals. Should your pump use a V Seal design contact us for assistance with finding compatible seals.

See Additional Information for a list of compatible pumps.
