No solvents or pipe wrenches necessary. Just use a PIPECONX Elbow or Tee to repair or replace your existing ones quickly and easily. Just cut the old fittings out at the joint and replace with our strong yet flexible PIPECONX replacements. Reduce sizes if necessary with separately supplied bushings (see page 17). Connect all common household drain, waste and vent pipes quickly and easily just by tightening the stainless steel bands using a common slotted screw driver or a 5/16” nut driver or socket.
