Replacement U-seal kit for Karcher, Hotsy, Landa, and Legacy pumps with 18mm plungers. This kit contains three complete 18mm plunger-seal sets, one per cylinder: each set is seven pieces: a high-pressure U-seal, a low-pressure U-seal, an O-ring, two white PTFE support rings and two steel backing washers, 21 pieces in the kit (Hawk-made, Karcher-packaged; the card carries 8.725-356.0 and 10998830). One kit services all three cylinders. Rated for temperatures up to 185°F. Replace this kit if your pump is leaking water from between the pump head and body. Note: This kit does NOT include the brass pressure rings or brass intermediate rings. If the brass shows wear, order the complete seal packing kit with brass instead.
