ABSTRACT:
A compression coupling for flexible hose, piping or tubing which has an annular sleeve which surrounds the adjacent ends of the tubes or pipes. The sleeve has the form of a circumferentially extensible annular band with an axially extending gap. A jacket member is attached at one end to the sleeve and extends over the gap. An axially extending wrinkle is formed in the jacket member directly over the gap, and a sealant is placed within this wrinkle. Means for clamping the jacket member to the sleeve on the other side of the gap are provided so that as the clamping means is tightened, the sealant is forced into the gap providing a complete circumferential seal. The coupling has an easily-handled unitary construction which uses a minimum of gasket material. It is also light in weight due to the lack of concentric multiple layers.
