Superior performance PTFE sheet with high compressibility

KLINGER®tc-1003 is a high quality, yet cost-effective biaxial oriented modified PTFE gasket material with hollow glass spheres. This material offers superior sealability, excellent torque retention, and reduced creep relaxation.

Uses include most chemicals. It also works well on glass-lined flanges. Gaskets cut from this material are exceptionally effective when lower bolt loads are needed to effect a seal.

This material also meets FDA conformity.

Basis: Modified PTFE material with hollow glass spheres.

The ability of a gasket to make and maintain a seal depends not only on the style and quality of the gasket material, but also on medium being sealed, the flange design, the amount of pressure applied to the gasket by the bolts and how the gasket is assembled onto the flanges and tightened. These factors are beyond the manufacturer's control.
