Product Overview

Application and service highlights

Introduction

Expanded PTFE adhesive tape is used for on-site gasket preparation and sealing of irregular or large flange faces where conventional cut gaskets are less practical. The adhesive backing helps positioning during assembly and simplifies field installation.

Key Features

  • Convenient for custom gasket formation directly at the installation point.
  • Adhesive backing helps hold the tape in position during assembly.
  • Useful for large, complex or irregular flange sealing surfaces.
