12 x 20 x 5.3 Fabric/NBR High Pressure Water Pump U-Cup Metric

This 1 piece sealing set was designed for low pressure water pumps and pressure washer cleaning equipment. It is used downstream of the W1 set, seals the low pressure leakage return, and 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. W3 is pictured. W2 part numbers do not contain a thermoplastic header ring.
