VS-PS19A

Flanged V-Spring-loaded high-pressure rotary seal for spinning bore.

Designed to provide long service life and low friction for extreme service applications over a wide temperature range.

This seal style is able to operate efficiently in environments where the operating parameters vary over a wide range. Cycling of pressure, speed or temperature can all be accommodated, as can mechanical torsion due to changes in movement type or direction. The seal is clamped on the flanged heel, preventing it from rotating and forming a positive static seal area. Also available in small quantities for repairs and seal replacement in 1 to 3 days.
