Expanded PTFE Gasket Material

EPTFE (Expanded PTFE)

Is a Universal sheet gasket material for most services under 600° F. Seals rough and irregular surfaces. Made from biaxial oriented expanded PTFE sheeting that is laminated to the required thickness. Seals of up to 3000+psi can be achieved depending on the flange type & design and type of media being sealed. Chemically resistant over the 0-14 pH range. Specific gravity: 4 to 6. Suitable for temperatures to 600° F.
