Nibco, Inc. 611 Copper Bullhead Tee

Copper bullhead tee for 1/4 in and 3/8 in tubes

This sweat fitting joins two 1/4 inch copper tubes and one 3/8 inch copper tube in a tee configuration. It is intended for potable water systems where a branch line must step up from a smaller main. The wrot copper body provides the corrosion resistance required for drinking water service. Plumbers and DIY installers use it when a supply line splits to a larger fixture supply.

Check tube sizes and joint method before ordering

Verify that the existing tubing matches the 1/4 inch and 3/8 inch nominal copper tube sizes listed for each port. The fitting uses sweat cup connections, so a torch, flux and lead-free solder are required for installation. Confirm local code permits copper sweat joints for potable water in your area. No threading or compression adapters are included with this fitting.

Fits into copper plumbing assemblies as a branch

The tee connects directly to copper tubing without additional adapters when tube diameters match the specified sizes. It frees the installer from using separate reducers or bushings to step between 1/4 inch and 3/8 inch lines. The compact adapter tee shape keeps the joint profile low inside walls or cabinets. Surrounding pipe supports and straps must be supplied separately to secure the completed assembly.
