1 in. Size PVC

11 products

1" PVC fittings are best for making light-load PVC projects such as laundry carts & garden structures.

FORMUFIT 1" PVC fittings and pipe products are an ideal size for indoor and outdoor home projects. They work best to build items such as laundry carts, garden structures, and playhouses.  These include cat hammocks, dog agility equipment, and light shelving.

  • External-fit 1" Size PVC products have a socket diameter of 1-5/16" (1.315 in.), which is equal to the actual outside diameter of a 1" size PVC pipe.
  • Internal-fit products will only fit 1" Schedule 40 size PVC pipe, which has an average inside diameter of 1.049 inches.  Internal-fit products will not work with Schedule 80 or thinwall PVC pipe sizes.
