DESCRIPTION
The Hallite T513 deep profile, beveled lip, loaded polypack is a U-cup utilizing a polyurethane shell energized by a highly resilient O-ring. At zero or low pressure the O-ring helps to increase the sealing force preventing any bypass. As the system pressure rises the sealing force increases and the O-ring ensures complete lip actuation under most conditions.
This seal provides extra stability needed to resist rolling in the groove. This extra stability together with the precision-trimmed sealing lips provides improved life and sealing. The deep profile, beveled-lip, loaded polypack is best used as a rod seal.
