Method and apparatus for a sleeve for hose couplings which has an arched wall section which tapers toward its opposing ends so that the sleeve will fit snugly against the hose coupling. Furthermore, the sleeve has peripheral slots for containing a pair of O-rings to help seal the sleeve to each of the hose couplings. Additionally, the sleeve is contoured to match the shape of the inner wall of the hose coupling so that the sleeve forms a seal against an internal gasket contained in each of the hose coupling.
