Abstract

Sealing apparatus seals off between first and second member faces and about registered ports opening at the faces, the members being relatively movable. The apparatus comprises: A. first and second concentric tubular inserts carried by one of the members for relative telescopic movement, the inserts extending about the port in said one member, at least one of the inserts having an end portion projecting endwise outwardly relative to said one member to be forcibly engaged by the other member for inwardly displacing said one insert in response to said member relative movement toward one another, and B. elastomeric means located between said inserts to transfer compressive force from said one insert to the other insert in response to said inward displacement of the one insert, and to be compressively urged in an outward direction into annular sealing engagement with the face of said other member about the port mouth therein.
