Legend Valve 111-M Hydronic Tee 1-1/8 Inch Od Brass

Product Description

The LEGEND VALVE 111-M is a brass compression hydronic tee designed for branching connections in hydronic heating systems using 1 1/8 inch OD tubing. Built from corrosion-resistant brass, it delivers a secure, leak-free seal without soldering, making it well-suited for boiler trim, sensor circuits, and auxiliary flow routing. The compression fitting design allows for faster installation and easier service compared to sweat connections. This tee handles the demands of high-temperature hydronic environments while maintaining long-term joint integrity in both new installs and retrofit applications.

This fitting is used in residential and light commercial hydronic heating systems where 1 1/8 inch OD specialty tubing is routed through boiler trim assemblies, pressure communication circuits, and low-flow hydronic distribution lines. It is particularly useful in applications where soldering is impractical or where quick disconnection may be required during servicing. Plumbers and hydronic heating technicians working on boiler piping layouts will find the compression design a reliable choice for maintaining flow circuit integrity.

Key Features

• Brass construction resists corrosion in high-temperature hydronic service
• Compression sealing eliminates the need for soldering or open flame during installation
• 1 inch nominal size with 1 1/8 inch OD compatibility for specialty boiler piping
• Tee configuration supports branching for sensor circuits, auxiliary lines, and pressure taps
• Serviceable design allows disassembly and reassembly without damaging the fitting or tubing

Compatibility

Designed as an OEM-style compression tee for hydronic heating systems utilizing 1 1/8 inch OD tubing in boiler trim and auxiliary circuit applications.

Installation Notes

Installation should be performed by a licensed plumber or qualified hydronic heating technician. Shut down the boiler and depressurize the system before disconnecting or modifying any hydronic piping. Ensure tubing ends are cut cleanly and deburred before seating in the compression fitting to achieve a proper seal. Follow applicable plumbing codes, including IPC guidelines, for hydronic system piping and fitting installation.
