If you know the size in liters, bladder material, and accumulator style (SB330 (3000 PSI) or SB600 (6000 PSI)), then selecting the correct bladder repair and/or seal kit becomes routine. If you are unsure of the bladder material then the fluid being utilized must be provided. For bladder-to-fluid compatibility information, please see the previous FAQ above. With the information known, you can select the proper repair kit and/or seal kit from our catalog located at: Catalogs > Select Accumulators catalog from the list, you can also search for spare Parts, Seal Kits & Tools from the search bar at the top. For repair kits and seal kits other than Buna N, and for sizes and types not listed please contact HYDAC.
