High performance material with superior sealability

KLINGER®tc-1005 is a high quality, yet cost-effective biaxial oriented modified PTFE gasket material with silica. This material offers superior sealability, excellent torque retention, and reduced creep relaxation. Gaskets from KLINGER®tc-1005 are exceptionally effective when the reliability of a low deforming material is required.

Uses include most chemicals and all concentrations of sulfuric acid.  This material also meets FDA conformity.

Basis: Modified PTFE material with silica.

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.
