Copper Bullhead Tee for potable water

This NIBCO 611 copper tee joins two 5/16 in tube ends to a 1/4 in branch using sweat connections. Wrought copper construction makes it suitable for potable water lines. The bullhead layout lets the larger run feed a smaller outlet in a single joint. No threading or mechanical fasteners are required.

Plumbers running 5/16 in copper trunk lines

Installers who need to drop from a 5/16 in main to a 1/4 in fixture supply will find this fitting matches the tube sizes exactly. Systems built on different tube diameters or press-fit joining methods cannot use this sweat tee. Builders needing a straight coupling or a reducing coupling should select a different fitting shape.

Bullhead run 5/16 in to 1/4 in branch

The defining specification is the bullhead sizing: both run ports take 5/16 in copper tube (7/16 in OD) while the branch port takes 1/4 in tube (3/8 in OD). If the branch must be the same size as the run, this tee will not work. Verify the tube outer diameters before brazing.

Questions about this item

Will the copper tee add any noise or heat when water runs through it all day?

The wrot copper tee has no moving parts, so it adds no noise or heat during continuous water flow.

What copper tube sizes must I already have for this 5/16 in by 5/16 in by 1/4 in bullhead tee to work?

You need 5/16 in copper tube for the two run ends and 1/4 in copper tube for the branch end.

Can I sweat this tee onto existing copper pipe that has been in the wall for years?

Yes, the cup connections are designed for standard sweat soldering onto clean copper tube.
