Nibco, Inc. 611RR Copper Reducing Tee 1/4 x 5/16 x 1/4

Copper Reducing Tee 1/4 x 5/16 x 1/4

This sweat fitting tee connects three copper tubes using cup connections on every outlet. It is made from wrot copper and suits potable water systems. The reducing layout steps the middle branch down to 5/16 inch while the two straight branches remain at 1/4 inch. Plumbers use it to join supply lines of different diameters in residential and light commercial work.

Sweat joint reliability under pressure

Once soldered, the cup joints form a permanent metallic bond that does not loosen with vibration or thermal cycling. The wrot copper body resists corrosion and maintains its shape when the system is pressurised for long periods. No mechanical fasteners or gaskets are present to degrade over time. The fitting is rated for standard potable water pressures found in typical installations.

Copper tube sizing constraint

The cup connections accept only the listed outer diameters of 3/8 inch, 7/16 inch and 3/8 inch respectively. Builders who need a different combination of tube sizes cannot use this fitting. It also cannot be adapted to threaded, compression or push-fit pipe without additional components. The reducing tee shape fixes the flow path to one smaller branch between two equal larger branches.
