A.y. Mcdonald 5426-016 Cts Push-on Tee 3/4x1/2x3/4 Brass

Product Description

The A.Y. MCDONALD 5426-016 is a brass CTS push-on removable tee fitting sized 3/4 inch x 1/2 inch x 3/4 inch. It connects copper tube size tubing using a push-on mechanism that requires no soldering, crimping, or special tooling at the joint. The removable design allows the fitting to be disconnected and repositioned during installation or service, making it practical for tight spaces or systems that may need future adjustment. At 0.40 pounds, it is a compact, solid-brass fitting suited for residential and light commercial plumbing applications. Licensed plumbers and pipefitters are the primary installers.

This tee is intended for use in CTS plumbing systems where a reducing branch connection is needed. The 3/4 inch run with a 1/2 inch branch outlet accommodates common domestic water distribution layouts, including main-to-branch transitions in supply lines. Its push-on connection type makes it a time-saving option during rough-in work or repair scenarios where torch-free joints are preferred or required.

Key Features

• Push-on removable connection — no solder, no crimp tool required
• Solid brass construction for durability in potable water service
• 3/4 inch x 1/2 inch x 3/4 inch reducing tee configuration
• CTS type — compatible with standard copper tube size tubing
• Lightweight at 0.40 pounds for easy handling in confined spaces

Compatibility

Designed as an OEM-style replacement or new-installation fitting for CTS plumbing systems requiring a 3/4 inch x 1/2 inch x 3/4 inch reducing tee with push-on connections.

Installation Notes

Installation is performed by a licensed plumber following applicable IPC and local plumbing code requirements. Shut off the water supply and depressurize the line before inserting or removing the fitting. Ensure tubing ends are cut square, deburred, and clean before pushing into the fitting to achieve a proper seal. Because the fitting is removable, verify the connection is fully seated and confirm no leaks under working pressure before closing up the work area.
