Watts Brass Tubular 3520-0808 Swivel Elbow 3/8x1/2 Cts

Product Description

The WATTS BRASS TUBULAR 3520-0808 is a female quick connect swivel elbow fitting designed for copper tube connections in residential and light commercial plumbing systems. It accommodates 3/8-inch by 1/2-inch copper tube sizes and holds up to 250 psi working pressure. The one-piece design eliminates loose components, reducing the chance of missing parts during installation. Licensed plumbers and experienced DIYers install this fitting in water supply lines where a low-profile, reliable elbow connection is needed. It carries NSF-14, NSF-61, and CSA/ASTM certifications and is listed under UPC code approval.

This swivel elbow is suited for residential water supply applications including behind-wall installations without access panels and direct in-ground burial installations, both of which are code-approved uses for this fitting. Its quick-connect mechanism simplifies tight-space work where threading or soldering is impractical. The fitting serves as a direct replacement for Qest and Flare It type fittings, making it a common drop-in solution on retrofit and repair jobs.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC).

For in-ground burial applications, confirm local code acceptance and use appropriate bedding material around the fitting.
