DWK DURAN Silicone Seal GL 45 PTFE Coated

The DWK DURAN Silicone Seal GL 45 PTFE Coated is a premium-quality sealing solution designed for laboratory glassware with GL 45 threaded closures. This seal features a high-purity, platinum-cured silicone core coated with PTFE (Polytetrafluoroethylene), combining the flexibility of silicone with the exceptional chemical resistance of PTFE. The PTFE coating protects the silicone from chemical attack, ensuring durability and compatibility with aggressive chemicals, making it ideal for applications involving corrosive substances, high-purity solutions, and temperature-sensitive processes. The seal is suitable for use with all sizes of DURAN GL 45 laboratory bottles and provides a liquid-tight closure when used in combination with the red PBT GL 45 open-topped screw cap.
