High-purity ePTFE Gaskets with Diffusion Barrier

Description and Applications

TEADIT® TEADIT 28LS-LE is a new generation of gaskets produced from 100% pure, multi-directionally expanded PTFE. The biocompatible gaskets are designed for use in the pharmaceutical, chemical and food industry. A diffusion barrier ensures extraordinarily high sealability at very low gasket stress.

TEADIT 28LS-LE gaskets are therefore ideal for - but not limited to - sealing connections where only very low surface pressure can be applied, i.e on plastic or glass flanges.
