Material

Selecting the wrong gasket can be a timely and costly mistake. Let our experienced THS sales team recommend the most durable and cost effective gasket material for your application by providing us with the pressure, temperature and process liquid details.

Buna (NBR/Nitrile), EPDM or Viton materials are the most common plate & frame heat exchanger gaskets depending on the operating application.

Food Grade
Standard Grade
Aggressive Chemical Compounds

Changes in Gaskets:

  • Time – Relaxes
  • Temperature – Deteriorates
  • Oxidizing Agents – Hardens
  • Swelling – Chemical Absorption

Gaskets Material Depends on:

  • Fluids Used
  • Temperature and Pressure

Standard Gasket Styles

Clip - will usually have rubber tabs that are visible from the outside of the heat exchanger

Glue – no tabs and in most cases the brown glue is visible under the gasket; typically used in high pressure or high temperature applications

Ball - used in HVAC or FDA applications to allow for easy removal in the field
