The Sleeve coupling was invented by Kenneth R. Cornwall on 26th August 2014 bearing patent number US8813336B1.

The present invention relates to a waterproof sleeve coupling for use in a partition for preventing liquid from leaking through a penetration in the partition either adjacent to or through the sleeve coupling. The sleeve coupling has a water stop constructed of a resilient material and mounted in sealing contact with a sleeve so that a waterproof seal is formed between the water stop and the sleeve. The sleeve coupling optionally includes an extension coupling and an extension sleeve mounted on the sleeve. When the sleeve coupling is mounted in the partition, the extension sleeve extends beyond the surface of the partition to prevent liquid on the surface of the partition from leaking into the passageway of the sleeve coupling.

The sleeve coupling of claim 1 wherein the water stop has opposed ends with a sidewall extending therebetween and a flange extending outward from the sidewall of the water stop in a direction away from the sleeve. The sleeve coupling of claim 2 wherein the flange is positioned at one end of the water stop.
