PTFE Adhesive Gasket – Teflon & Self-Adhesive PTFE Sealing Elements
PTFE gaskets (Teflon gaskets) and self-adhesive PTFE gaskets are high-performance sealing elements used in industrial pipelines, valve connections, pump bodies, and mechanical assemblies. They provide outstanding chemical resistance, low friction, and excellent sealing — particularly in applications involving aggressive fluids. The self-adhesive variant offers easy positioning and fast installation during assembly.
100% PTFE (Teflon) material: PTFE is resistant to virtually all chemicals including acids, bases, solvents, and oils — making these gaskets the preferred choice for chemically aggressive process environments across chemical, pharmaceutical, and marine industries.

Frequently Asked Questions
A PTFE gasket is a sealing element manufactured from 100% polytetrafluoroethylene (Teflon). It provides exceptional chemical resistance, low friction, and reliable sealing across a wide temperature range. PTFE gaskets are widely used in chemical, pharmaceutical, and industrial applications where aggressive fluids are present.
Self-adhesive PTFE gaskets have a high-performance industrial adhesive backing that holds the gasket in position during assembly — preventing slipping or misalignment on vertical or overhead surfaces. This significantly speeds up installation and reduces the risk of improper seating.
PTFE gaskets are used in industrial pipe and flange connections, chemical and petrochemical plants, corrosive fluid transfer lines, valve bodies, pump covers, marine systems, and any process environment requiring sealing against aggressive chemicals or extreme temperatures.
Flowland PTFE gaskets are rated for continuous use between -200°C and +260°C, making them suitable for both cryogenic and elevated-temperature applications. This wide range makes PTFE one of the most versatile gasket materials available.
PTFE is resistant to virtually all industrial chemicals including strong acids (hydrochloric, sulphuric, nitric), strong bases, solvents, oils, fuels, and water. It is one of the most chemically inert materials available, making it the preferred choice for aggressive fluid applications.
