Series 1 - T-11A cavity, EPDM, cartridge seal kit

990011014 : Series 1 - T-11A cavity, EPDM, 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.

  • EPDM seals have no limited shelf life.
  • EPDM seals are purple in color for easy stock and field identification.

Notes [ + ]
  • Install back-up rings and O-rings as shown in views.
  • See installation variations for models associated with alternative installation views.
  • When installing continuous back-up rings, use the same technique and the same care used to install O-rings.
  • When installing cartridge - be sure to torque to recommended value.
  • Cartridges with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
