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.
The outer diameter of the dust wiper adopts interference fit to achieve technical sealing at the cylinder end face. Its wiping edge can effectively block the ingress of dust and contaminants while permitting the backflow of residual oil film. The rear support area prevents tilting of the dust wiper, and this product is applicable to Type A housings complying with ISO 6195 standard.
