A.y. Mcdonald 5426-006 90 Degree Push-on Elbow 3/4 in Cts

Product Description

The A.Y. MCDONALD 5426-006 is a 90-degree push-on elbow fitting designed for copper tube size (CTS) plumbing applications. Constructed from brass, this fitting accepts 3/4-inch CTS pipe with a tool-free push-on connection that is also removable, allowing for adjustments or disassembly during installation. The removable design sets it apart from permanent press-fit fittings, making it a practical choice for installations where future serviceability matters. Licensed plumbers and pipefitters install this type of fitting in residential and light commercial water distribution systems where a directional change is needed without soldering or threading.

This fitting is suited for 3/4-inch CTS copper or compatible plastic tubing in potable water supply lines, hydronic distribution, and general plumbing rough-in work. The push-on, removable connection style speeds up installation in tight spaces where a torch or pipe wrench cannot be easily used. It is appropriate for both new construction and retrofit work where minimal disruption to surrounding materials is required.

Key Features

• 90-degree elbow geometry for directional changes in CTS plumbing runs
• Push-on, removable connection — no solder, no crimping tool required
• 3/4-inch CTS fitting size for standard copper tube compatibility
• Brass construction for corrosion resistance and durability in water service
• Lightweight at 0.35 pounds per fitting, easy to handle in confined spaces

Compatibility

Designed as an OEM-style replacement and general-use fitting for 3/4-inch CTS copper tube plumbing systems in residential and light commercial applications.

Installation Notes

Installation is performed by a licensed plumber. Shut off the water supply and relieve system pressure before making or breaking any connection. Ensure tube ends are cut cleanly and deburred before inserting into the push-on fitting to achieve a proper seal. Follow local plumbing codes, including applicable IPC requirements, for fitting use in potable water systems.
