Expanded PTFE Round Cord Valve-spindle cord made of pure expanded PTFE, used as valve-spindle and flange seals in the chemical, pharmaceutical and food processing industries. Flanges are sealed quickly and securely by simple insertion of a ring of PTFE round cord (Ends twisted)
The Expanded PTFE Round Cord cord has high residual thickness at time of installation and highest recovery properties. The round expanded PTFE has very good adaptability to shafts and flange surfaces and very low sliding friction. The PTFE cord is avery clean material, harmless in contact with food. It's often used as sealing for valve spindle, for shaft seals, tube flanges, as PTFE cord sealing for tanks, in the apparatus engineering, machine housings, food processing systems, pharmaceutical systems.
The Expanded PTFE cord is compliant to FDA standard
