Pure PTFE Gasket | High Purity Chemical Resistant Flange Seal

Engineered for perfection in the most demanding environments, Chunhuan’s Pure Virgin PTFE Gaskets are the definitive solution for sealing corrosive chemicals, high-purity fluids, and viscous media. Machined from 100% virgin PTFE without any fillers or additives, these gaskets deliver absolute chemical inertness and guaranteed purity, ensuring a safe, reliable, and contamination-free seal for critical applications across chemical, pharmaceutical, food, and semiconductor industries.

Unrivaled Sealing Performance & Benefits

• Absolute Chemical Inertness: Offers unparalleled resistance to virtually all aggressive media, including concentrated acids, strong caustics, and powerful organic solvents, ensuring long-term integrity and safety in chemical processing.
• Guaranteed High Purity & Compliance: Made from 100% virgin PTFE, our gaskets are inherently FDA compliant and meet USP Class VI requirements. They ensure zero contamination, making them ideal for sensitive applications in food, beverage, pharmaceutical, and biotech industries.
• Exceptional Temperature Versatility: Performs reliably across an extreme temperature spectrum from cryogenic -200°C to continuous +260°C. It remains flexible at low temperatures without becoming brittle and will not melt at high temperatures.
• Superior Non-Stick & Low Friction: The naturally non-stick surface prevents the adhesion of sticky materials and allows for easy clean-up and gasket removal, reducing maintenance downtime.
• Excellent Conformability & Sealability: The material’s inherent softness and flexibility allow it to easily conform to flange surface imperfections, creating a effective seal with lower bolt loads, minimizing flange stress.
