Inside Couplings


(ISC Series: ISC-4.0, ISC-3.0, ISC-2.0, ISC-1.5, ISC-1.0)



  • Great in tight areas where several pipes are routed tight to each other.
  • Couples schedule 40 PVC pipe inside the pipe.
  • Available for 1", 1 1/2", 2", 3" and 4".


  • The four inch unit doubles as either an inside coupling or a reducing bushing. The four inch fits inside four inch schedule forty pipe on both ends. It can also be used as a three inch outside coupling and therefore as a four inch inside to three inch outside reducing bushing.

  • The three inch performs a similar function with three inch and two inch schedule forty pipe.

  • These fittings are particularly useful in the repair of tight, multi-pipe plumbing areas.
