Legend Valve 302-205nl Mono-flow Tee 1x3/4 in Lead-free

Product Description

The LEGEND VALVE 302-205nl is a lead-free cast brass mono-flow tee designed for hydronic heating systems. It connects 1-inch nominal supply and return lines to a 3/4-inch branch, allowing a controlled diversion of hot water flow to individual zone radiators or convectors without requiring a circulator on every zone. The sweat (solder) end connections suit standard copper tubing installations. Cast brass construction provides durability in closed-loop hydronic circuits operating under typical residential and light commercial pressures and temperatures.

This fitting is used in residential and light commercial hydronic heating systems, specifically in mono-flow or single-pipe baseboard radiator loops. A plumber or hydronics technician installs this tee in-line on the main supply loop where a branch takeoff to a terminal heating unit is required. The fitting body geometry creates a slight pressure differential that induces flow through the branch without interrupting the main loop circulation.

Key Features

• Lead-free cast brass construction meets drinking water safe and hydronic system requirements
• Sweat (solder) end connections compatible with standard copper tubing
• 1-inch x 1-inch main run with 3/4-inch branch outlet for mono-flow hydronic loop applications
• Cast brass body provides resistance to corrosion in closed-loop hydronic systems
• Compact footprint: 1.2 inches long, 1.85 inches wide, 2.7 inches tall

Compatibility

Designed as an OEM-style replacement or new-installation fitting for single-pipe mono-flow hydronic heating systems using copper sweat connections on 1-inch main loop and 3/4-inch branch piping.

Installation Notes

Installation is performed by a licensed plumber or hydronics technician. Drain and depressurize the hydronic system and allow pipes to cool fully before cutting into the loop and soldering this tee in place. Use proper flux, lead-free solder, and follow local plumbing codes, including applicable IPC requirements for hydronic systems. Ensure all sweat joints are fully cleaned, fluxed, and heated evenly before applying solder to achieve a leak-free connection.
