Profile XB56 is an internal face U-Cup seal designed to work on SAE flanges. It provides a high degree of deflection over the contact faces due to the U-shaped grove in the seal face and being activated by system pressure.
It is preferred in circumstances where the flange faces may part under system pressure, if this is not a concern, we recommend the use of our XB58 profile for increased leak-free operation.
It is commonly supplied in one of our high-performance polyurethane materials but can be manufactured in rubber materials for increased chemical and temperature resistance where required. We can manufacture this seal to suit non-standard sizes and include anti-extrusion devices if the application pressure requires.
