Sea Tech Union Elbow 1/2 Copper Tube

Turn a corner without tools using the Sea Tech 1/2-inch Union Elbow (ST05UE) from Watts Water Technologies. This 90-degree push-to-connect elbow links two lengths of 1/2-inch CTS tubing around tight bends, eliminating the kinks and stress that result from forcing rigid pipe or tubing through a turn. No solder, no glue, and no special tools are required to make a secure, leak-free joint at the angle your layout demands.

Like all Sea Tech AquaLock fittings, this elbow relies on a corrosion-resistant stainless steel gripper ring that interlocks with multiple tubing materials. That single-fitting compatibility with PEX, copper, and CPVC simplifies both your toolkit and your parts list, since you no longer need separate elbows for each material. The zero-leak O-ring guide protects the seal during insertion, aligning the tubing each time and preventing the O-ring from dislodging, while the locking clip adds an extra measure of connection security.

Sharp directional changes are unavoidable in real-world plumbing, where supply lines must navigate around framing, fixtures, and equipment. Bending tubing too tightly to make those turns risks kinking the line, restricting flow, and creating a weak point that can fail later. A dedicated elbow makes the turn cleanly and predictably every time.

With no flow-restricting stiffeners needed on copper and CPVC, you preserve full flow and avoid added head loss even where the line changes direction. Elbows like this are invaluable when routing supply lines around obstacles in tight mechanical spaces. For plumbers and water-treatment installers, this Sea Tech union elbow makes clean directional changes fast, reliable, and easy to rework whenever the layout demands a different path. Compact and dependable, this union elbow belongs in every installer's kit for the countless directional changes that any real-world plumbing or water-treatment layout inevitably demands. Carry a few in different angles and sizes, and you are equipped to route tubing cleanly through almost any space a job presents.
