TvnSeal Engineering Plastics Technology Co., Ltd. is a national high-tech enterprise specializing in the R&D and manufacturing of high-performance sealing materials and special polymer new materials.
O-ring preloaded low-friction PTFE rotary seals. They are primarily applied in operating conditions with alternating pressure on both sides of the seal, such as hose reel rotary joints, slewing bearing raceways and hydraulic systems for machine tools. Excellent chemical resistance and heat resistance can be obtained by selecting appropriate O-ring materials.
