513 U-Cup
513 (Rod Seals)
The profile 513 is a standard profile loaded U cup utilizing a polyurethane or polyester shell energized by a high specification resilient O ring. At zero or low pressure, the O ring helps to increase the sealing force preventing any bypass. As pressure rises the sealing force increases and the O ring provides complete lip actuation under most conditions. The precision trimmed sealing lips insure optimum sealing action.
