3 in MS2 Long Test Ball Plug

Engineered for waste stack testing and sealing wye connections during sewer air tests, this plug accommodates pipe diameters ranging from 4 in to 6 in. The design features molded-in sealing ribs to maintain a secure, leak-free barrier within the pipe. Its extended length allows for simultaneous sealing of the wye vertical riser and the sewer run, providing versatility for complex plumbing configurations. The multi-stage deflation process is specifically designed to prevent backsplash during removal. This unit is backed by a 1-year limited warranty.
