Bronze reducing elbow for potable water

This 90-degree reducing elbow joins a 1-inch copper tube to a 1/2-inch FNPT thread. The bronze body meets NSF/ANSI 61 and NSF/ANSI 372 for drinking-water safety. It is rated for 385 psi at up to 200 degrees F. The fitting suits residential and light-commercial plumbing systems.

Replaces separate reducer and elbow assemblies

Combining the reduction and turn in one piece cuts joint count and solder time. The jump is worth it when space is tight or when fewer potential leak paths matter. The sweat cup on the 1-inch side and FNPT on the 1/2-inch side match common supply transitions. ASME B 16.18 and ISO 9001 compliance back the design.

Verify tube size and thread compatibility

Confirm the 1-inch copper tube outer diameter matches the 1 1/8-inch cup. Ensure the mating 1/2-inch male pipe threads are clean and undamaged. Check that system pressure and temperature stay within the 385 psi and 200 degrees F limits. The C87850 bronze grade is not suited for all chemical environments.

Questions about this item

What tube outer diameter must the copper pipe have to fit the cup end?

The cup end requires a copper tube with a 1 1/8 in outer diameter for a proper sweat joint.

How is the sweat end joined, and what step do installers often skip?

Clean the cup and pipe, apply flux, heat evenly, and feed solder until the joint is full; the step often skipped is removing all flux residue after cooling.

What maintenance or replacement will this bronze elbow need over time?

Bronze resists corrosion in potable water, so the elbow itself rarely needs replacement; inspect joints periodically for leaks and re-sweat if a joint ever weeps.
