TEF-STEEL Tri-Clamp

PTFE Encapsulated Stainless Steel Gaskets

About Our TEF-STEEL Products

Tef-Steel gaskets are manufactured from a PTFE and SS powder and then sintered (cooked).  There are no layers, the gasket is grey because the powder mixes *white PTFE and Gray SS. 

Tef-Steel Tri-Clamp Gaskets offer superior chemical resistance and a broader temperature range due to their Teflon-encapsulated stainless steel construction. The outer layer is Teflon (PTFE), while the core is stainless steel, providing a durable and chemically resistant construction. These gaskets are manufactured with precision and ensure a high level of sanitation and product purity.

  • The stainless steel enhances the gasket’s resistance to aggressive chemicals and corrosive substances.
  • Can withstand a wider range of temperatures due to the stainless steel core, suitable for both high and low-temperature processes.
  • Offers a smooth surface, which facilitates easy cleaning and minimizes the risk of product adhesion.
  • Preferred for applications where higher chemical resistance and broader temperature ranges are required, such as in pharmaceuticals and certain chemical processes.
  • Preferred for High temperature environments including steam service
