NA1088

Controlled Swell Sheet

Applications

Style NA1088 is used in difficult to seal applications where inadequate bolt loading or flange surface conditions are not ideal, in low to moderate flange load conditions.

  • Petroleum and Derivatives
  • Synthetic oils
  • Aliphatic solvents
  • Mild organic acids
  • Water
  • Coolants
  • Refrigerants
  • Vegetable oils
  • Animal oils

Construction

Style NA1088 is a high density, controlled swell sheet gasket material with a proprietary binder & reinforced with a synthetic/inorganic fiber blend. It is designed for demanding applications requiring excellent sealablity, torque retention, recovery, and conformability to uneven flange surfaces. The material provides a controlled swell in the presence of oils, fuels, lubricants, and water/coolant. It is used in heavy duty & industrial oil sealing applications such as diesel engine oil pans and front covers, compressors, generators, pumps, valves, gear boxes & housings, transformer, sight glass, man/hand-hole covers. The following specification values are for 0.8mm (0.031”) gauge material.
