Nichias NAFLON PTFE Envelope Gasket (PTFE Core T1995) Flange Gasket

A PTFE wrapping type gasket in which the core material such as a joint sheet is coated with a PTFE outer skin.
Since the sealing surface is completely covered with a PTFE film and has excellent non-staining and chemical resistance, it is used in a wide range of applications such as fine chemicals, petrochemicals, pharmaceutical and food industries, and general industries.
Various corrosive fluids, fluids that dislike contamination with organic solvents Where electrical insulation is required
* Depending on the type of fluid, the fluid may penetrate inside the gasket through the PTFE coating material. In particular, nitric acid, ethylene oxide, halogens (chlorine, bromine, etc.), molten sulfur, monochloroacetic acid, etc. may permeate during long-term use and attack the central material, causing the gasket to lose its function.
In such cases, we recommend that you replace the gasket as soon as possible or use a PTFE solid gasket.
