PTFE Flange Gasket
This PTFE (Polytetrafluoroethylene) flange gasket is a high-performance sealing component designed for process pipelines with demanding chemical and temperature requirements. It provides a reliable, leak-tight seal between flanged connections, preventing media leakage and external contamination. Made of pure PTFE, it meets the strict hygiene standards of food, beverage, pharmaceutical and chemical industries, ensuring safe and consistent performance in critical process systems.
PTFE Flange Gasket
Key Features
- Outstanding Chemical Resistance: Resistant to almost all acids, bases, solvents and corrosive media, suitable for aggressive process environments.
- Wide Temperature Range: Withstands temperatures from -200°C to +260°C, ideal for both cryogenic and high-temperature applications.
- Hygienic & Non-Contaminating: Food-grade, non-toxic and physiologically inert, suitable for direct contact with food, beverage and pharmaceutical media.
- Low Friction & Non-Stick Surface: Prevents media buildup and adhesion, ensuring easy cleaning and compatibility with CIP/SIP processes.
- Durable & Dimensionally Stable: Maintains its shape and sealing performance under pressure, with minimal creep or cold flow.
