KIT 174 SEAL, 16mm *1 EA*

SKU: 1921

Kit 174 is a single-cylinder seal service set for 16 mm plungers — the high- and low-pressure seals and supporting rings for one cylinder of a triplex plunger pump, packaged for a one-hole reseal. In a triplex pump each cylinder has its own seal stack, and this kit gives you the components for one of the three: water seals on the head side, the seals that keep pressure separated, and the backup hardware that holds everything seated. It is the right choice when only one cylinder is weeping or after a single plunger is replaced. Before ordering, confirm your plunger diameter measures 16 mm and that Kit 174 matches your pump's parts list — a seal kit for the wrong plunger size will not seal.
