Trelleborg Launches New Flat Gasket Range

The range includes specialist materials for use with harsh chemicals.


Trelleborg Sealing Solutions (Fort Wayne, IN) has launched HMF FlatSeal, a new range of flat gasket materials for effective static sealing in low and high-temperature applications. The range includes specialist materials for use with harsh chemicals and mediums in aerospace, automotive, oil & gas, food & beverage, chemical processing and pharmaceutical industries.  

The HMF FlatSeal range includes 20 materials, from a standard material for low to moderate pressure and temperature applications to engineered solutions for high-pressure, high-temperature environments, and even specialist materials for food contact applications with FDA and other conformities. Specifically:                       

  • HMF FlatSeal flat gaskets are available in four product groups; an innovative mix of high-quality aramid fibers and Nitrile Butadiene Rubber (NBR), expanded graphite, polytetrafluoroethylene (PTFE), or phlogopite mica materials, to provide a wide range of specialist capabilities, outstanding mechanical stability, and compliance with fugitive emissions requirements.   
  • The addition of an innovative in-organic treatment is available for graphite-based flat gaskets, which improves the long-term oxidation properties of the gaskets in high-temperature applications to extend the service life. 
  • The treatment also provides anti-stick properties to facilitate the removal of the gaskets and minimizes the cleaning effort of the flanges.
