Expanded PTFE Gasket - Pliable material with high heat and chemical resistance


PTFE (Teflon®) is expanded to create a fibrous internal structure that makes it soft and pliable. Expanded PTFE will conform easily to uneven or rough surfaces, but it has low creep (aka cold flow) under pressure. PTFE is highly chemical resistant and can withstand temperatures from -240°C up to +270°C (and up to 315°C for short periods).

Used for:
Expanded PTFE gaskets are used as a sealing material in bolted flange joints in pipelines, hydraulic systems, and pneumatic systems. It is often used as a cost-effective alternative to sheet gaskets on flanges with large diameters where the cutting of sheets is impractical. The extruded gasket profile can fit any flange shape, so it’s not necessary to stock different gasket shapes and sizes.

The gasket has an adhesive on one side that allows for easy installation on vertical surfaces.

Use expanded PTFE for an inert teeth protector.
