  • Plumbing coupling and method of use
    Patent number: 6116262
    Abstract: A plumbing coupling (20) for connecting two lengths of pipe (500) includes a cylindrical body (22) having a circumferential through-slit (32) extending part of the way around its perimeter (28). A closure plate (36) is selectively insertable into the through-slit (32) so as to abut the inner surface (24) of body (22) and block the flow of water through the plumbing coupling (20). A sleeve (42) is selectively wrapable around body (22) to tightly seal the closure plate (36). To conduct a pressure test, closure plate (36) is inserted and sleeve (42) attached. To return the plumbing line to normal use, middle portion (43) of sleeve (42) is peeled back, closure plate (36) is removed, and middle portion (43) of sleeve (42) is reattached. Body (22) is fabricated from a resilient material which conforms to edge (38) of closure plate (36).
