28 x 38 x 9.75 Fabric NBR/POM/TFE High Pressure Water Pump U-Cup Metric

This 2 or 3 piece sealing set was designed specifically for high pressure water pumps and pressure washer cleaning equipment. This new design replaces the higher friction chevron solution. This sealing set has a much longer service life due to less friction and a specially lubricated NBR and Cotton material. It works well in water and water/oil mixture fluids. Part numbers with a B suffix contain a carbon-filled Teflon backup ring.
