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.
This compact piston seal features an almost dead-space-free design, complying with requirements for food and pharmaceutical industry applications. It is also a popular alternative to O-rings, as the outer diameter interference fit effectively prevents twisting under dynamic operating conditions.
