Sea Tech 1117-1515 15mm Metric Union Elbow Quick-Connect Fitting

The Sea Tech 1117-1515 is a 15mm x 15mm Metric Union Elbow push-to-connect fitting designed for marine, RV, and residential plumbing systems. Part of the Sea Tech (now Watts AquaLock) quick-connect system, this elbow delivers a reliable 90° direction change in tight spaces — no tools required for installation.

Simply cut tubing to length and push it into the fitting for a secure, leak-free connection. The fitting connects on the outside of the tubing, maximizing flow rates and eliminating the restriction caused by inner barbs. Fittings can also rotate freely under pressure, making them ideal for vibration-prone marine and RV environments.
