Abstract
A lip-seal for sealing the junction between two parts includes a body for mounting on one part, a sealing lip extending therefrom for application against the other part, and an inflatable chamber defined between the body, the lip and a diaphragm extending between, and connected to, the lip and the body, the arrangement being such that on inflation of the chamber the profile of the lip is modified so that it is moved away from the other part to permit the other part to be assembled with the one part without damage to the lip seal and without premature application of the lip to the other part.
