Series 2 - T-2A cavity, Viton, cartridge seal kit

Sun offers replacement seal kits for all cartridge models. These kits include all of the external seals on the cartridge along with installation instructions. Seal kits are available in Buna-N and Viton for all models, along with EPDM and polyurethane for many models. Please note: Converting the external seals from one material to another does not ensure fluid compatibility with that material due to the existence of internal seals within the cartridge.

• The shelf life for this cartridge seal kit is twenty years from date of purchase. This date will be printed on the kit packaging.
