Internal PVC Coupling
40 productsSeamlessly connect two segments of PVC pipe to add length or breakdown points in PVC structures.
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.
