Product illustrationPTFE Gasket
Resists many chemicals; non-stick surface
PTFE gaskets are typically cut from polytetrafluoroethylene sheet or molded to shape. They offer broad chemical compatibility and low surface adhesion for many corrosive services and flange joints with cleanliness requirements. This product category covers conventional PTFE gaskets, excluding the expanded, modified, and envelope constructions described separately in this guide.
- Standard PTFEMade of standard PTFE
- Easy removalNon-stick surface, easy to clean off
- Grade by useMaterial grade for cleanliness and insulation requirements
Features
- Material options for a wide range of chemicals, selected for the specific medium and temperature.
- Low surface adhesion facilitates clean disassembly.
- Available in ring, full-face, and nonstandard profiles.
- Electrical insulation, cleanliness, and food or pharmaceutical requirements are addressed through the appropriate material grade, manufacturing condition, and application specification.

Selection & service notes
Sustained load can cause creep and stress relaxation. Selection focuses on gasket thickness and width, flange rigidity and bolt load. Expanded or modified PTFE can be considered for low assembly loads or dimensional stability using the specific material data.
