Is there a PVC fitting that will allow me to put a 2"pvc pipe INSIDE a 4" PVC pipe, like a pipe in a pipe?

I need to plumb a 2" pipe inside a 4" pvc pipe. All the fittings I have seen that are reducer fittings will stop my 2" from sliding inside the 4" line, which makes sense, but I need the 2" to slide inside the 4", I guess you would say it needs to telescope. PLEASE READ.... I know that there are reducers for pipe, but I need one that will allow the 2" PVC pipe to slid eALL of the way INSIDE the 4" pipe, not just into the reducer fitting. All standard reducers have a stop that holds the small pipe from sliding all the way inside the larger. I want one without the stops as I need to pipe to slide inside the larger one.

  1. Of course there is.. Go to any store such as Lowe's/Ace/Home Depot and get the reducers necessary.. EASY !!
  2. a reducer fitting is the way to go,i think you should try other places.
  3. Not exactly sure what you want but I would enlarge the 2 inch bushing by putting it on a lathe so the 2 incher will slide through it instead of binding. Sanding might work but would take a lot of time. A forstner bit on a drill press might work. Not sure of the spelling but it is the drill that makes flat bottomed holes in wood. But go slow speed as you don't want to heat up the PVC. Cut away the stop. I've done this many times for special cases. The bushing will be narrower but will still work.
  4. Remove the stop on the 2" reducer using a rattail or half round file.
  5. use a dremel tool to grind the plastic stop ring away, then the pipe will slide thru the reducer..... To easy !!!!
  6. agree with bob g... but curious of what your actually up to mr unibomber..
  7. all pvc fittings will have a stop not letting the pipe go inside. Use a rubber boot called fernco. This will let you adjust depth. i do not understand why, but good luck
  8. You'll have to modify a bushing to allow the 2" PVC to slide. It's slightly tapered and also has a stop inside. Just grind it out and used a fine sanding drum to smooth it out.
