Sea Tech Union Ell, 1 CxC

The Sea Tech 1-inch Union Elbow (ST10UE) from Watts Water Technologies brings tool-free push-to-connect convenience to full one-inch CTS tubing, routing the line through a clean 90-degree turn without solder, glue, or tools. At this larger size, used on main service lines and high-demand water-treatment runs, a reliable elbow that maintains full flow while changing direction is a genuine advantage that protects system pressure.

Sea Tech AquaLock fittings are engineered around a corrosion-resistant stainless steel gripper ring that interlocks with multiple tubing materials. That means this one-inch elbow handles PEX, copper, and CPVC with a single fitting and no special tools. The zero-leak O-ring guide protects the seal during insertion, aligning the tubing on every push and preventing the O-ring from being dislodged, while the locking clip adds extra connection security on these higher-flow lines where a failure would have the greatest impact.

• 90-degree union elbow for 1-inch CTS tubing (CxC)
• Push-to-connect installation with no tools required
• Stainless steel gripper ring grips PEX, copper, and CPVC
• Locking clip and patented zero-leak O-ring guide for sealed joints
• No flow-restricting stiffeners needed on copper and CPVC
• Built for larger main and treatment-system supply lines
• One elbow serves multiple tubing materials for simpler stocking

One-inch lines carry serious flow, often serving as the main artery feeding a home or facility's softeners, filters, and downstream plumbing. Making a directional change on a line this size without choking it is critical, and traditional methods like soldering large copper or cementing CPVC are time-consuming and unforgiving of error.

Maintaining full flow matters most on larger pipe, and because no stiffeners are required for copper and CPVC, this elbow turns the line without restricting it or adding head loss. For installers building or servicing whole-house plumbing and commercial-grade water-treatment systems, the Sea Tech 1-inch union elbow delivers a fast, secure, and reworkable directional change that stands up to the demands of a main supply run for years. For main arteries that feed an entire home or facility, this dependable one-inch elbow gives installers a fast, full-flow way to navigate corners without the time, mess, and risk of soldering or solvent cement. Keep one on hand for those larger runs and you can make a clean, full-flow turn in seconds rather than minutes, finishing the job faster.
