Product Description

Pure Graphite Braided Ring Discription:
Tenglong's pure graphite gaskets are crafted from high-purity expanded graphite and are free of any binding agents. They are capable of withstanding temperatures as high as 1202°F (650°C). These seals exhibit excellent chemical inertness and high thermal conductivity. They are impregnated with a corrosion inhibitor that ensures the preservation of the material's integrity. This passive inhibitor forms a protective layer between the valve components and the graphite gaskets, acting as a barrier to prevent direct contact and subsequent corrosion between the two electrically conductive materials. This inhibitor provides long-lasting protection for your equipment.
Pure Graphite Braided Ring Features :
Low clamping for an optimum sealing
Easy assembly and disassembly
Use even on damaged or deformed flanges
Improved reliability
Prevents corrosion of equipment
