Materials

High-quality fibers, the right impregnation and the perfect braid type are the key components for producing an efficient and effective packing gasket. Several factors can make the difference between a quality product that will last a full production cycle with little material wear, and a low-cost packing that, after initial purchase savings, can incur many additional costs during its operational life.
