3-inch 45° copper elbow for sweat-fit plumbing

This wrot-copper elbow joins two 3-inch copper tubes at a 45-degree angle using cup-to-cup sweat connections. It handles potable water, air and gases in residential and commercial piping systems. The fitting is rated for 317 psi at 100 degrees F and up to 400 degrees F. New condition ensures clean, oxidation-free surfaces for reliable solder joints.

Cup-to-cup sweat connection with 3-inch tube size

The single specification that decides fitment is the 3-inch copper tube size on both ends with cup connections. Both ports accept 3 1/8-inch outside-diameter tube for direct soldering without adapters. Verifying the tube size and connection type against your existing piping confirms compatibility before purchase.

No accessories or software bundled

The product ships as a single fitting with no flux, solder, tools or documentation included. Installers must supply their own soldering materials and follow local plumbing codes. The absence of bundled consumables means the buyer sources compatible flux and alloy separately.

Questions about this item

What does the 45-degree angle mean for flow in a real installation?

The 45-degree sweep provides a gentler change of direction than a sharper elbow, helping maintain smoother flow of air, gases or potable water through the copper tube.

What does the 317 psi at 100°F rating cap in practice?

It sets the maximum operating pressure for the fitting when the system temperature is at or below 100 degrees Fahrenheit; higher temperatures lower the allowable pressure.

What tube size and connection type does this elbow need to fit?

It fits 3-inch copper tube with a 3-1/8-inch outside diameter on both ends, using sweat cup connections that are soldered in place.
