High-Conductivity Graphite Gasket Sheets for Specialized Sealing Applications

Reinforced with Stainless Steel – Designed for Heat Exchangers, Engines, and Electronic Equipment | Anti-Oxidation | Long Service Life

Product Overview

Our high-conductivity graphite gasket sheets are precision-engineered to deliver long-lasting, leak-proof sealing under severe thermal and mechanical conditions. Combining flexible graphite with stainless steel reinforcement, these composite sheets are ideal for demanding applications such as heat exchangers, engine exhaust systems, steam pipelines, and electronic equipment cooling units.

Each sheet is developed for environments requiring extreme temperature resistance, electrical conductivity, and chemical stability, making it a preferred choice for both OEM manufacturing and maintenance operations worldwide.

Distinctive Advantages

✅ Enhanced Conductivity: Graphite layers ensure exceptional heat and electrical transfer, maintaining sealing integrity even under fluctuating temperatures.
✅ Reinforced Structure: A 0.2–0.25 mm perforated stainless steel insert (SS201, SS304, or SS316) strengthens dimensional stability during cutting and operation.
✅ Outstanding Thermal Performance: Withstands continuous service up to 800 °C, suitable for gas turbines, reactors, and pressure vessels.
✅ Superior Corrosion Resistance: Performs reliably with steam, hydrocarbons, and aggressive fluids — ensuring extended gasket lifespan.
✅ Precision Engineering: Available in customized thicknesses (1.0–6.0 mm) and carbon purities (95–99%), offering tailored solutions for diverse industrial needs.
