1-1/4 inch Cast Brass Baseboard Reducing Tee – For Hydronic Heating Applications

The 1-1/4 inch Cast Brass Baseboard Reducing Tee is designed for use in closed-loop hydronic heating systems, particularly where transitions are required between primary supply lines and smaller branch lines, such as those found in baseboard radiator circuits. The cast brass body offers strength and thermal resilience suitable for high-temperature applications common in residential and light commercial systems.

Application and Performance

This reducing tee allows for seamless distribution of hot water from a main line to baseboard heating elements while maintaining consistent flow characteristics. The cast brass construction ensures mechanical integrity under thermal expansion and pressure cycling.

• Material: Cast Brass – corrosion-resistant and suitable for hot water circulation systems.
• Size: 1-1/4 inch x 1/8 inch x 1-1/4 inch
• Connection Ends: Sweat (Copper Tube Size) x FIP x Sweat – allows transition from copper tubing to threaded terminal fittings.
• Pressure Rating: Typically tested up to 125 PSI for hydronic system compatibility.

Installation Notes

All sweat connections must be cleaned and properly fluxed before soldering. Use of lead-free solder is required to meet code. The female-threaded branch is designed to accommodate air vents, drain valves, or baseboard components. Verify compatibility with heating system design specifications and expansion requirements.

Typical Use Cases

This fitting is used in hydronic baseboard heating loops to reduce pipe diameter between a main supply line and branch components. It is suitable for systems using Type L or Type M copper tubing and can be integrated into both new installations and replacement scenarios.

Regulatory Compliance

Meets current U.S. plumbing codes requiring the use of lead-free components in potable water and heating systems. Always confirm installation practices meet applicable local and national code requirements.
