PTFE Gasket – precision-molded sealing solutions engineered from high-purity PTFE resin for unmatched chemical resistance, thermal stability, and non-stick performance. Manufactured in China by Kaxite, these gaskets deliver leak-proof sealing across chemical processing, pharmaceutical, and industrial applications where traditional materials fail.
PTFE gaskets are high-performance sealing components manufactured by compression molding PTFE (polytetrafluoroethylene) granular resin into precise shapes and dimensions. As a leading China PTFE gasket manufacturer, Kaxite produces these gaskets for critical sealing applications in chemical processing, pharmaceutical manufacturing, food processing, and semiconductor industries where chemical compatibility and purity are essential.
Compared to other sealing materials, PTFE offers universal chemical resistance (pH 0–14), an exceptionally wide temperature range (-200°C to +260°C), and the lowest coefficient of friction of any solid material. Our PTFE gaskets are available in raised face (RF) and flat face (FF) configurations, with thickness options from 1mm to 3mm, and can be customized to any size or shape per customer specifications.
Universal Chemical Resistance
pH 0–14 – resistant to virtually all acids, bases, solvents, and aggressive media
Wide Temperature Range
-200°C to +260°C – suitable for cryogenic and high-heat applications
Low Friction & Non-Stick
Coefficient of friction 0.05–0.10 – prevents adhesion and eases installation
Precision Molded
Compression molded for consistent density, dimensional accuracy, and smooth finish
FDA-Compliant Grades
Available in food-grade and pharmaceutical-grade formulations
Custom Configurations
Any size, shape, or thickness – RF, FF, or custom flange designs
