Junjin Spare Parts SEALING KIT J507360C

The Junjin Spare Parts SEALING KIT J507360C is a direct-fit replacement for specific hydraulic cylinders. It’s made to stop leaks and keep pressure steady where original seals wear out first.

You get all the O-rings, backup rings, and rod seals in one pack. No extra cutting or guessing—each piece matches Junjin’s factory specs for J507360C.

The rubber compound handles high heat and hydraulic oil without swelling. We’ve seen these kits outlast generic seals by a good margin on skid steers and compact loaders.

Installation is straightforward if you’ve done cylinder work before. Clean the gland and piston thoroughly, then slide the new seals in place—lube them before assembly to avoid pinching.

Check the old seals for scoring on the rod surface before fitting this kit. If the rod is damaged, even a new J507360C won’t hold for long. Keep a spare kit on the truck for emergency rebuilds.
