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.
Hydraulic oscillating rotary seals with integrated back-up rings adopt outer diameter interference fit to guarantee stable installation within housings. The back-up ring design accommodates larger extrusion clearances and higher operating pressures. This product is mainly applied to oscillating rotary joints of equipment such as excavator grabs.
