Copper 45° Elbow for Drain Lines

This wrot-copper 45-degree elbow connects 3/4-inch nominal tube with C x C solder joints. It is rated for 582 psi at 100 °F and handles continuous temperatures from -20 °F to 400 °F. The fitting meets ASME/ANSI B16.22 and suits residential and light-commercial drainage installations.

Solder-Joint Installation and Common Issues

Clean both tube ends and the fitting sockets, apply flux, then sweat the joints with a propane or MAPP torch. The most frequent problem is insufficient heat, which leaves cold solder and slow leaks. Overheating can anneal the copper and weaken the joint, while excess flux residue causes long-term corrosion if not flushed.

Pressure and Temperature Limits

The 582 psi rating applies only at 100 °F; allowable pressure drops as temperature rises toward the 400 °F maximum. The fitting is not rated for steam service or for pressures above the stated limit at any temperature. Designers must verify that system conditions stay within the ASME/ANSI B16.22 pressure–temperature envelope.
