MRG Gaskets

MRG Gaskets consist of a metal core, generally of stainless steel, with a smooth finish on either side.

A sealing layer is usually applied on both sides and depending on the duty the material for this layer can be graphite, PTFE (Teflon), Mica, Novus Therm or soft alloys like aluminium or silver. The sealing material layers protect the flange surfaces from damage as well as providing an excellent seal.

MRG gaskets have a wide seating stress range which makes them:

  • Highly suitable for varying temperatures and pressures.
  • Less sensitive to assembly faults (inaccurate bolt tensioning).
  • Suitable for both light and heavy designed flanges.
  • Temperature resistant up to approx 1 000 °C dependent on layer material. Resistant to media pressures up to 40 bar.
  • When assembled the remaining thickness of the sealing material is extremely low (0.2 - 0.25 mm) thus reducing leaks, fail rates and environmental pollution.
  • Will not damage flange surface and is easily removed.
  • MRG gasket cores are re-usable after cleaning, inspection, profile tracing and relayering with new sealing material. This is of particular interest in the case of costly heat exchanger gaskets when using Monel and other exotic materials.
  • Reduces maintenance costs and leakage.
