Shop Enerpac hydraulic cylinder seal kits for servicing and rebuilding compatible Enerpac cylinders. These model-specific seal kits help restore sealing performance, reduce hydraulic leakage and support reliable operation in demanding industrial applications.
Seal Kits for Enerpac Hydraulic Cylinders
Hydraulic cylinder seals are critical to maintaining pressure, controlling fluid leakage and preserving cylinder performance. Over time, seals can wear from pressure cycles, contamination, heat and normal service conditions.
This collection includes seal kits for a wide range of Enerpac hydraulic cylinder families, including high-tonnage cylinders, lock nut cylinders, low-profile cylinders and other industrial lifting and positioning cylinders.
How to Choose the Correct Cylinder Seal Kit
Enerpac cylinder seal kits are model-specific. Before ordering, identify the complete model number of the hydraulic cylinder and confirm the corresponding seal kit in the applicable Enerpac repair parts documentation.
When selecting a seal kit, verify:
- The complete hydraulic cylinder model number
- The cylinder series and capacity
- The specified Enerpac seal kit part number
- Any model revision or seal-material requirements
Similar-looking cylinders may use different seal kits, so compatibility should be confirmed by model number rather than appearance alone.
Maintain Reliable Hydraulic Cylinder Performance
Replacing worn seals can help restore hydraulic pressure, reduce external and internal leakage and extend the service life of an existing cylinder. Proper maintenance is especially important for cylinders used in lifting, pushing, pulling, positioning and heavy industrial applications.

Frequently Asked Questions
How do I find the correct Enerpac cylinder seal kit?
Locate the cylinder model number and use the corresponding Enerpac repair parts documentation to identify the correct seal kit part number.
Are Enerpac hydraulic cylinder seal kits interchangeable?
No. Seal kits should be matched to the specific cylinder model or series identified by Enerpac.
When should hydraulic cylinder seals be replaced?
Common signs include hydraulic leakage, pressure loss, reduced cylinder performance or visible wear discovered during routine maintenance.
What is the difference between a seal kit and a repair kit?
A seal kit is primarily intended to replace sealing components, while a repair kit may contain additional internal service components needed for a more complete rebuild.
Find your seal kit by cylinder series
Seal kit numbers start with the cylinder model or series. These are the families in this collection.
| Cylinder series | Cylinder type | Example kits |
|---|---|---|
| RC | General purpose, single-acting, spring return | RC102K, RC2510K, RC102KV, RC506KV |
| RCH | Hollow plunger | RCH121KV, RCH503K, RCH603KV4 |
| RCS and RSM | Low height | RCS302KV, RCS1002KV, RSM50KV, RSM200KV |
| RR and RRH | Double-acting | RR1006KV, RR5013KV, RRH1001K4V |
| RD | Precision production, double-acting | RD46KV, RD910KV, RD1610KV |
| RWH | Single-acting hollow | RWH302KV |
| RAC | Aluminum | RAC10K, RAC15K |
| HCG, HCL and HCR | High tonnage | HCG100K1, HCL100K, HCR100K1; K1 and K2 versions fit different builds of the same capacity |
| LPL | Low height lock nut | LPL602K, LPL1002K, LPL5002K |
| CDB | Double-acting block cylinder | CDB10K1 |
| TR | Tie rod | TR15SK, TR20SK, TR25SK, TR32SK, TR40SK |
Where a cylinder has more than one kit, such as K and KV versions or K1 and K2, the right one depends on the cylinder's production version and build. Check the repair parts sheet for your cylinder, or call (704) 463-1070 with the model number and we will confirm it.
Seal kit replacement tips
- Work clean. Enerpac warns that dirt in the system can cause pump, cylinder and valve failure.
- Check the other wear parts while it is apart. Inspect the plunger, stop ring, wiper and bearings. See Hydraulic Cylinder Repair Parts.
- Refill with Enerpac oil. See Enerpac Hydraulic Oil.
Hydraulic equipment should be serviced by a qualified hydraulic technician, as Enerpac's instructions state.
