Garlock 5102

The Garlock 5102 is a structured PTFE (polytetrafluoroethylene) gasketing material manufactured by Garlock. PTFE is valued in industrial sealing applications for its exceptional chemical inertness, meaning it resists degradation from a very wide range of corrosive substances.

Garlock 5102 is designed for severe chemical service environments where standard gasket materials would fail, including chemical processing plants, pulp and paper mills, and petrochemical facilities. Its PTFE construction allows it to handle aggressive acids, bases, and solvents that would rapidly degrade compressed non-asbestos or graphite gaskets.

Structured PTFE materials such as Garlock 5102 are engineered with specific fillers and structural modifications to improve creep resistance and compressibility compared to pure expanded PTFE sheet. This allows the gasket to maintain a tighter seal under thermal cycling and bolt-load relaxation, which are common failure modes in flanged chemical piping systems.

As a PTFE-based gasket, Garlock 5102 is rated for a wide operating temperature range that typically spans from cryogenic conditions up to approximately 500°F (260°C), consistent with the thermal limits of PTFE. Specific pressure ratings depend on the flange design and bolt load applied, and should be verified against Garlock's published technical data sheets for the intended service.
