About Seal Kits
A seal kit is a set of sealing components used to repair or maintain hydraulic or pneumatic cylinders in machinery. It typically includes:
- Rod seals - prevent fluid leakage from the cylinder
- Piston seals - maintain pressure within the cylinder
- Dust seals / wipers - keep dirt and contaminants out
- Wear rings / guide rings - prevent metal-to-metal contact
- O-rings & backup rings - ensure tight sealing and support
Purpose: Seal kits restore hydraulic performance, prevent oil leakage, maintain system pressure, extend equipment lifespan, and reduce downtime and maintenance costs.
