Hydraulic Seal Replacement Kits for Lift Trucks & Pallet Jacks

Restore hydraulic performance and stop leaks with the right seal replacement kit for your pallet jack or forklift. Our Seal Replacement Kits collection includes complete hydraulic cylinder seal kits, pump seal kits, and o-ring assortments matched to the most common makes and models in the industry — so you can complete a full hydraulic rebuild without hunting down individual seals.

Compatible equipment brands include Crown, Toyota, BT Prime Mover, Multiton, Raymond, Yale, Hyster, Uline, and other major OEM and aftermarket manufacturers. Kits are matched by equipment make, model, and serial number range, as well as by pump manufacturer and cylinder bore size.

Kit types available:

  • Hydraulic Cylinder Seal Kits — all seals, o-rings, and wipers needed to rebuild a lift cylinder
  • Pump Seal Kits — seals and o-rings for hydraulic pump units (Monarch, Parker, Haldex, and others)
  • Complete Hydraulic Rebuild Kits — cylinder and pump seals bundled for a full system overhaul
  • O-Ring Assortments — general-purpose metric and SAE o-ring sets for field repairs

How to select the right seal kit: Identify your equipment's make, model, and serial number from the data plate. For pump seal kits, note the pump manufacturer (often stamped on the pump body) — common suppliers include Monarch, Parker, and Haldex. For cylinder kits, note the cylinder bore diameter and rod diameter. Matching these specs ensures the seals seat correctly and hold pressure.

Common use cases: Scheduled hydraulic maintenance, repairing slow or failed lift function, stopping oil weeping from cylinder rods or pump fittings, and full hydraulic rebuilds during equipment refurbishment. Replacing seals proactively at 2,000–3,000 operating hours is standard practice for high-cycle equipment.

All kits ship from our US warehouse. Use the brand and model filters above to find your kit, or search by pump manufacturer and model for a direct match.

Choosing a seal kit

A seal kit replaces the wear items inside a hydraulic pump unit — the parts that harden, shrink and weep long before anything metal fails. Replacing the seals is usually far cheaper than replacing the pump.

Signs the seals have gone

  • The forks drift down under load instead of holding
  • Oil weeping around the pump body or ram
  • The handle needs more strokes than it used to to reach full lift
  • Visible fluid on the floor beneath the unit

What we stock

Seal kits for both manual and electric equipment, covering Crown, Toyota, BT Prime Mover, Multiton, Blue Giant and Mobile among others. Kits are matched to the specific hydraulic unit rather than to the truck, so two trucks of the same brand can take different kits.

Before you order

Identify the hydraulic unit, not just the truck — the unit is normally stamped with its own number. If you are unsure, the hydraulic unit diagrams show the exploded view for most common units, or call 1-800-669-7554 with your model and serial number.
