The 621 type seal is a top-of-the-range twin lip rod seal designed to provide a dry sealing solution in heavy-duty applications. The secondary sealing lip located behind the primary sealing lip improves stability of the seal in the gland. The unique profile of the NBR energiser ensures the precision trimmed primary sealing lips maintain contact under low or no pressure situations while ensuring proper sealing at higher pressures. The seal also incorporates an acetal anti-extrusion ring to withstand side loads and extreme pressure peaks even with the extrusion gaps, which are the result of using remote plastic bearing strips. The seal shell is molded in Hythane 181, Hallite's high-performance polyurethane, for easy installation and excellent low temperature performance.
