NIBCO 906-2 Copper DWV Street Elbow
This NIBCO 906-2 fitting is a 45-degree DWV street elbow made from wrot copper. It connects a 1-1/2 inch cup end to a 1-1/2 inch FTG end using sweat connections. The fitting suits air and potable water lines in drainage, waste and vent systems. It meets ASME B16.29, ASTM B75 and ISO 9001 standards for material and dimensional quality.
Capacity and pressure headroom
The elbow handles a maximum operating pressure of 5 psi and a maximum operating temperature of 400 degrees F. These ratings suit low-pressure DWV installations and hot water distribution within the stated limits. The fitting runs out of headroom in pressurised supply lines or high-temperature steam applications that exceed the 5 psi or 400 degrees F thresholds.
45-degree sweep for DWV flow
The single specification that decides fit is the 45-degree sweep angle combined with the street configuration. This geometry provides a gradual directional change for gravity drainage while the cup-to-FTG ends allow direct insertion into a hub or another fitting. Buyers needing a 90-degree turn or a cup-to-cup joint cannot use this part.

Questions about this item
Will the 45-degree DWV street elbow fit my existing 1-1/2" copper DWV piping?
Yes, both the cup and FTG ends are sized for 1-1/2" copper tube with a 1 5/8" outer diameter, matching standard DWV dimensions.
How can I verify the 906-2 elbow is correctly installed and leak-free?
Pressurise the system up to 5 psi and inspect the sweat joints; a proper solder seal will hold pressure without weeping.
Does the NIBCO 906-2 come with solder or flux, or must I buy them separately?
The box contains only the wrot copper elbow; solder, flux and cleaning tools are sold separately.
