Tri-Went can produce 180 degree return bends, crossovers and hairpins in sizes ranging from 3/16" (0.188) OD to 3-1/8" (3.125) OD. These bent parts can be produced with straight legs and off-set legs. The ends of these bent tubes can be expanded, reduced, saddled, chamfered, beaded or flared and some sizes are available with solder rings. Our u-bends can be made out of copper, carbon steel, copper-nickel, stainless steel, aluminum, nickel and brass.
