Abstract:
1. A sleeve for sealing the ends of first and second hose couplings, the hose couplings for conveying fluid, comprising: a) a first and second coupling, each said coupling having a first enlarged end and a second unenlarged end, a hose being attached coaxially to each said unenlarged end of said coupling, wherein said first and second couplings are adapted for having said enlarged end be connected to each other; b) an internal circumferential slot disposed proximate said enlarged end of each said first and second coupling, a gasket disposed in each said first and second slot, an inner flap portion disposed on said gasket, said inner flap portion having a surface extending longitudinally along said coupling a short distance; c) a cylindrically shaped sleeve, said sleeve coaxially disposed in said enlarged ends of said couplings, said sleeve having a convex shaped outer wall, wherein substantially said entire surface of said inner flap portion of each said gasket contacts said outer wall of said sleeve for providing a first seal on said coupling so as to prevent leakage of fluid from said couplings when said couplings are connected to each other; d) a first and second external circumferential slot disposed on said outer surface of said sleeve, wherein said external slots are parallel to each other and spaced apart, an O-ring disposed in each said external slot; and e) wherein one said O-ring contacts said enlarged end of one said coupling so as to provide a second seal on said coupling so as to prevent leakage of fluid from said coupling when said couplings are connected to each other.
