Abstract
A V-ring seal is disclosed for sealing between relatively rotatable surfaces in which the V-ring seal comprises PTFE and includes a body with an inner side for abutting against a first surface and a lip extending from the body towards a second surface, the lip including a rear side distal from the second surface, a front side proximate to the second surface, a lower portion proximate to the body, an upper portion distal from the body, a sealing surface on the front side of the lip for abutting the second surface to seal the second surface, and a resilient ring for providing a force acting on the lip to urge the sealing surface towards the second surface, the resilient ring being disposed on the front side of the lower portion of the lip whereby the resilient ring is concealed from the rear side of the lip.
