Series 1 - T-16A cavity, Polyurethane cartridge seal kit

990016002 : Series 1 - T-16A 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 and are more abrasion/extrusion resistant and are well suited for high cycle and high pressure applications.
