Catalogue description records
Seal Oil Pony Rod (part KP-24) is an oil seal for the pony rod, supplied 3 per set. The pony rod is the intermediate rod between the crosshead and the piston or plunger rod, passing through the oil-seal housing that separates the power end from the fluid end; this seal works at that rod to retain power-end oil and exclude contaminants. It fits Kerr JT40, KP-3300PT and T30M pumps. It is offered as an aftermarket replacement cross-referenced to Kerr part number KP-24; the brand and number are used for identification only and do not imply factory manufacture.
