PU BS Rod Seal having shorter inner sealing lip world trust hydraulic IDI seal nutrings are designed especially for rod applications. BS Rod Seal is the most critical seal on any type of fluid power equipment preventing leakage of fluid from within the cylinder to the outside. Besides, Leakage through the BS Rod Seal can reduce equipment performance. And also in extreme cases can cause environmental issues and therefore it is vitally important to choose the correct rod seal type and design to suit a particular application.
