Chemically Inert PTFE Gaskets and O-Rings for Sterile and Corrosive Media

Teflon (PTFE) Gaskets and O-Rings represent the ultimate solution for applications requiring absolute chemical inertness, wide temperature stability (-200°C to +260°C), and low friction performance. Teflon is immune to almost all industrial acids, organic solvents, and caustic chemical washdowns, making it the material of choice for cryogenic pipelines, chemical process columns, and sterile food or pharmaceutical piping.

Micro Engineering designs and manufactures custom Teflon gaskets, PTFE envelopes, and Teflon O-rings. Because virgin PTFE can experience cold flow (creep) under heavy loads, we supply specialized filled compounds—including glass-filled, carbon-filled, and bronze-filled Teflon. These fillers dramatically improve wear resistance, mechanical strength, and pressure limits while maintaining the outstanding chemical immunity of the fluoropolymer.

Widely utilized in pharmaceutical dosing loops, cryogenic liquid piping, strong acid reactors, and hygienic chemical processes.

Why Choose Our Teflon Gaskets & O-Rings?

Micro Engineering delivers precision-machined Teflon gaskets and PTFE O-rings designed to survive strong acid environments and clean sanitary media loops.

Universal Chemical Inertness

Immune to virtually all aggressive acids, bases, organic solvents, and high-pressure steam over a pH scale of 0 to 14.

Cryogenic to High Heat Range

Maintains mechanical elasticity and structural integrity in temperature extremes from -200°C up to +260°C.

Anti-Cold Flow Fillers

Custom filled options (Glass, Carbon, Bronze) are formulated to eliminate cold flow, creep, and extrusion under heavy loads.

Zero-Contamination PTFE

Physiologically inert, non-stick, and FDA compliant, preventing any media contamination in sanitary pipelines.
