About Technetics Group PTFE Gaskets and PTFE Seals

PTFE is chemically resistant to virtually all process chemistries, and is a fantastic gasketing material for cryogenic conditions. Our PTFE gaskets and seals are available in both standard and custom sizes, materials and designs. Choose the best for your application including:

  • TEXOLON® Encapsulated PTFE Gaskets. Suitable for exposure to extremely harsh chemicals, these PTFE encapsulated gaskets deliver enhanced sealing performance including excellent purity, low stress to seal, chemical capability, reduced creep and cold flow characteristics.
  • TEXOLON® PTFE Flange Gaskets. Our steel reinforced pipe flange gaskets are a proprietary molded PTFE gasket featuring a stainless steel grade 304 perforated reinforcement core.
  • CHEMISEAL® PTFE Envelope Gaskets. Our PTFE envelope gaskets offer positive, trouble-free sealing in most applications, including in severely corrosive environments and glass-lined vessels.
