Our custom PTFE gaskets are made from 100% virgin polytetrafluoroethylene (PTFE), known for its outstanding chemical resistance, wide temperature tolerance, and ultra-clean sealing capability. These PTFE sealing gaskets are ideal for static sealing in flange connections, valves, pumps, and reactor vessels, particularly in environments requiring extreme corrosion resistance and purity, such as chemical processing, pharmaceutical manufacturing, food-grade systems, and semiconductor cleanrooms.
Exceptional chemical resistance: Withstands over 98% of aggressive acids, bases, and organic solvents including hydrofluoric acid and sulfuric acid.
Wide temperature performance: Operates reliably from -200°C to +260°C, with short-term peaks up to 300°C.
FDA/EU food-grade compliant: Suitable for CIP systems, biopharmaceutical pipes, and sterilization lines.
Ultra-low friction: Permanent self-lubricating surface with a coefficient of friction ~0.05.
High dimensional stability: Supports ±0.1mm precision customization with multiple thicknesses available (0.5mm–10mm).
Excellent dielectric performance: Perfect for electrical insulation applications.
Non-contaminating: Made from pure resin with no fillers, suitable for ultra-high-purity use.
Chemical Equipment: Flange gaskets and static seals for acid/alkali pipelines, reactors, valves
Food Industry: FDA-compliant PTFE gaskets for sanitary pipe systems, mixing tanks, and filling machines
Pharmaceutical & Medical: Clean seals for GMP-compliant bioprocessing, sterilizers, and freeze dryers
Semiconductor Manufacturing: PTFE insulation gaskets for wafer carriers, ultra-pure gas systems
Green Energy / Hydrogen Electrolysis: Long-life PTFE sealing rings for alkaline medium sealing
Custom Machinery: Ideal for replacing worn-out metal gaskets in legacy or narrow joint assemblies
Customization flexibility: Any shape, thickness, diameter
High sealing integrity under low torque or irregular flange faces
Reduced maintenance downtime with longer gasket lifespan
Cleanroom compatible and non-leaching properties
Ready-to-ship standard sizes or fully customized orders
