Abstract
An engine comprises a pair of members, such as a pair of adjacent cylinder heads, having a common passageway formed therein to communicate a coolant therethrough. An annular seal assembly is disposed between the members to provide a static seal preventing the egress of coolant thereby. The seal assembly comprises an annular ferrule having an annular elastomeric seal disposed circumferentially thereabout. A V-shaped groove is formed circumferentially on the periphery of the seal to seat a like-shaped portion of the ferrule therein. A strap-type clamp circumferentially surrounds the seal to apply a clamping force thereon to wedge the ferrule into the V-shaped groove of the seal to expand sidewalls of the seal into sealing contact with the members.
