Gland Packing
High-carbon Corner-yarn Graphite Packing
Braided from high-carbon fiber corner yarn and flexible graphite yarn. The high-carbon fiber is impregnated with lubricant and blocking agent, making the packing both strong and flexible, with corner and core reinforcement for structural stability. Chemically stable, well lubricated, extremely low friction and highly conductive with shaft protection, widely used for pump and valve sealing across industries. Suitable for all media except fuming sulfuric acid, fuming nitric acid and aqua regia.
