PTFE Tri-Clamp Gaskets - High-Chemical-Resistance Hygienic Sealing Solution
PTFE Tri-Clamp gaskets are engineered for sanitary pipeline systems that demand superior chemical resistance, exceptional temperature stability, and ultra-clean surfaces. Made from virgin PTFE (Teflon), these gaskets provide a hygienic, inert sealing solution for Tri-Clamp fittings in food, beverage, pharmaceutical, biotech, chemical and laboratory applications.
2. Product Overview
PTFE is a high-performance fluoropolymer with outstanding chemical inertness and thermal stability. PTFE Tri-Clamp gaskets resist aggressive media, do not absorb process fluids, and maintain dimensional stability under thermal cycling - making them ideal where purity and long-term reliability are critical. They are compatible with standard stainless-steel Tri-Clamp/Tri-Clover fittings and suitable for CIP/SIP processes.
