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 mainly used for working conditions with alternating pressure on both sealing sides, such as hose reel rotary joints, slewing bearing raceways and machine tool hydraulic systems. Excellent chemical resistance and heat resistance can be achieved by selecting suitable O-ring materials.
