1-1/4 inch x 1-1/4 inch x 3/4 inch Cast Brass Reducing Tee – Corrosion-Resistant Fitting for Branch Transitions

The 1-1/4 inch x 1-1/4 inch x 3/4 inch Cast Brass Reducing Tee is a forged brass fitting designed for use in potable water, hydronic heating, and general plumbing systems. This tee allows for the connection of two equal-sized main lines with a reduced outlet, supporting directional flow control and branch integration in mixed-size systems.

Made from lead-free cast brass, this fitting provides high mechanical strength and corrosion resistance in pressurized environments. Threaded connections allow for easy integration with compatible brass, copper, steel, or CPVC components, depending on the application.

Key Features for Professional Installations

• ✅ Cast Brass Body – Delivers excellent thermal stability and structural integrity under operating pressures.
• ✅ Reducing Branch Configuration – Accommodates a 3/4 inch outlet on a 1-1/4 inch main line for systems requiring pressure zoning or flow rate reduction.
• ✅ Lead-Free Compliance – Certified for use in potable water systems in accordance with federal and state regulations.
• ✅ Standard Female NPT Threads – Compatible with widely used threaded piping systems.
• ✅ Code-Conforming – Manufactured to meet requirements of IPC, UPC, NSF/ANSI 61, and NSF/ANSI 372 where applicable.

Technical Specifications

• Material: Lead-Free Cast Brass
• Nominal Sizes: 1-1/4 inch x 1-1/4 inch x 3/4 inch
• End Connections: Female National Pipe Thread (NPT)
• Certification: NSF/ANSI 61 & 372 compliant for potable systems

Installation Guidelines

Apply approved thread sealant or PTFE tape to all male pipe threads before assembly. Ensure threads are clean and undamaged for proper sealing. Hand-tighten followed by wrench torque as specified for brass fittings. Avoid overtightening to prevent stress cracking or thread deformation. Suitable for both vertical and horizontal orientations in water or low-pressure fluid systems.

Typical Use Cases

Commonly installed in commercial and residential water distribution systems, especially where branch lines are reduced in size for fixture groups or pressure management. Often used in retrofits, zone valve manifolds, and mechanical room piping where dimensional transitions are required.

Regulatory Note

This fitting meets Safe Drinking Water Act (SDWA) lead-free requirements and is certified for use in jurisdictions enforcing NSF 61 and 372 standards. Always confirm local code acceptance prior to use in inspected systems.
