The 90 degree angled pipe fitting includes an inside and outside piece that clamp together with two nuts and bolts. The clamp design allows you to quickly change a connection while building or remove and reuse the connectors in a future project.Both pieces are designed with a pocket feature that locks the nut into place when tightening, this allows for a one tool assembly no matter which piece the nuts are on. Every connector comes with a pre applied friction band that makes connections even more secure. Order some 90 degree conduit connectors and add strong corner connections to your DIY pipe build!
