611 Bullhead Tee for Copper Potable Water

This NIBCO 611 sweat fitting joins two 5/8-inch copper tubes to a 3/4-inch branch in potable-water systems. The wrot-copper body provides a reliable cup-to-cup connection for each outlet. All three ends are sized for standard copper tube diameters.

Suits installers joining unequal tube sizes

Plumbers needing a straight coupling or a reducing tee with identical outlets should choose a different fitting. This bullhead tee is not for gas lines or non-potable fluids. It also does not fit press-connect or compression systems.

5/8 x 5/8 x 3/4 copper tube sizing

The run ports accept 5/8-inch nominal tube with a 3/4-inch outer diameter. The branch port accepts 3/4-inch nominal tube with a 7/8-inch outer diameter. Matching these exact dimensions determines whether the tee fits the installation.

Questions about this item

What pressure limit appears first during sustained use of this 611 bullhead tee?

The wrot copper construction handles typical potable water pressures; the joint strength depends on proper soldering technique and tube wall thickness rather than a single published limit.

How much heat does the fitting itself generate when water runs all day?

The copper tee adds no heat of its own; it simply conducts the water temperature, so pipe insulation is the only way to control surface warmth.

What tube sizes and tools must I already have to install this 5/8 x 5/8 x 3/4 tee?

You need 5/8 in and 3/4 in nominal copper tube (3/4 in and 7/8 in OD), a tubing cutter, emery cloth, flux, lead-free solder and a propane or MAPP torch.
