Join PVC to Transite Pipe

• 
  Use plastic pipe reducer, available at your hardware store.

FERNCO rubber and St. Stl. clamped fittings. Available in reducing couplings, bushings, couplings, elbows, sweep elbows, 90 deg elbows, 45 deg tees, and many others. Easy to use.

Answer to OP question is: 2" x 1-1/2" Fernco bushing and a 4" x 2" reducing coupling. Put the 4" end of the reducing coupling on the transite pipe and tighten clamp. Push 2" x 1-1/2" bushing into the 2" coupling end and tighten clamp. You now have a 4" x 1-1/2" coupling.

One piece units available from factory.

Good Luck, Old Salt
