What is a Seal Kit?
A seal kit is a set of sealing components used to repair or
maintain hydraulic or pneumatic cylinders in machinery. It
typically includes various types of seals such as:
✅ 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
