Transition between different pipe sizes in a DWV pipe system using the Snap-All® Increaser/Reducer Transition Bushing. Use bushing to connect 8 in. cast iron/steel/PVC pipe to 6 in. pipe or fittings and form an interlocking leak-resistant and gas-tight seal. Transition bushing snaps onto 6 in. pipe end and has outer grooves that nest into 8 in. pipe end to create a hassle-free connection point. Increaser/reducer bushing is compatible with Clamp-All® Hi-Torq 80 or Hi-Torq 125 hubless couplings. Durable Snap-All bushing is a one-piece molded out of neoprene material. Use fittings and other valves to set up a new irrigation system, expand an existing system, or make repairs.
