Internal PVC Coupling
Add length to an existing piece of PVC pipe easily with the FORMUFIT Internal Coupling. This coupling connects two Sch. 40 PVC pipe segments internally, with only a minuscule seam exposed. Internal Couplers are quintessential for breakpoints in larger applications and designs to help reduce transport size, or you can use them to create 10-foot lengths from our 40-inch or 60-inch PVC pipe segments without paying expensive freight.
FORMUFIT PVC External Couplers are available to buy online in the 1/2", 3/4", 1", 1-1/4" PVC Sizes and fit standard Schedule 40 PVC size pipe only. For sizing information, please see our PVC 101 page.
