No-Hub 3″Coupling with Stainless Steel Shield
No-Hub couplings have an inner gasket made of a synthetic rubber. The inner gasket is surrounded by an outer stainless steel shield with stainless steel worm clamps riveted to the shield to keep them in place. Stainless steel is used for corrosion resistance.
Easy to install, just slip-on pipe and tighten the two 5/16 hex-head screws. No-Hubs are very helpful when the piping is in a hard to reach place or the pipe is unable to be moved in either direction to allow the repair to be made with a glue-on fitting. For use with DWV non-pressurized connections
Inside Diameter 3 1/4″
Length 2 1/4″
