Series 1 - T-31A cavity, Polyurethane cartridge seal kit
Technical Features [ + ]
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 ten years from date of purchase. This date will be printed on the kit packaging.
- Polyurethane seals have a higher tensile strength, are more abrasion/extrusion resistant, and are well suited for high cycle and high pressure applications.
