Here's all the seal kits that have ever been used on the JCB 508C Telehandler. We are specialists in hydraulic seal kits, and supply customers globally with our kits.
If you are looking for seals for the JCB 508C, just pick from the kits above, and don't forget that on the 508C, some applications have two rams - like the boom lift rams, the stabilizer rams etc - and so you will need two sealkits if you are resealing both rams.
