Legend Valve 450-249 Copper Reducing Tee 1-1/2 x 3/4 x 1-1/2

Copper Reducing Tee for Plumbing

This Legend Valve copper reducing tee connects three pipes with a 1-1/2 by 3/4 by 1-1/2 inch inside diameter. It suits residential and light commercial water supply installations that require a branch line reduction. The C x C x C sweat connections accept standard copper tubing for permanent joints. Buyers who need a different reduction ratio or a threaded connection cannot use this fitting.

Sweat Joint Installation

The fitting installs by cleaning the tube ends, applying flux, and sweating each joint with a propane or MAPP torch. Overheating can burn the flux and weaken the bond, while insufficient heat leaves voids that leak. Proper tube support prevents stress on the joints during thermal expansion. Installers without brazing experience should practice on scrap before working on a live system.

Long-Term Service Behaviour

Copper resists corrosion in typical potable water and handles continuous pressure cycles without fatigue. The material tolerates sustained hot water temperatures far above normal domestic use. Scale buildup in hard water areas may gradually reduce the internal diameter at the 3/4 inch branch. The fitting carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm.
