1-1/4 inch x 1/2 inch x 1-1/4 inch Copper Reducing Tee – C x C x C

The 1-1/4 inch x 1/2 inch x 1-1/4 inch Copper Reducing Tee is engineered for use in copper water distribution systems, allowing for the intersection of a reduced branch line within larger main runs. Manufactured from high-grade, lead-free wrought copper, this fitting supports soldered joints that meet the demands of both new installations and retrofit work in potable and non-potable systems.

Specification and Material Details

• ✅ Standard: ASME B16.22
• ✅ Material: Wrought copper alloy (ASTM B75 or B88)
• ✅ Compliance: Lead-free under NSF/ANSI 61 & 372 for potable water use
• ✅ Type: Tee with reducing center outlet
• ✅ Connection: Cup x Cup x Cup (Solder connection)

Installation Guidelines

This reducing tee is intended for use in systems operating at or below 400°F and 200 psi when joined using lead-free solder. Proper surface preparation—including cleaning and fluxing—is critical to ensure a strong, corrosion-resistant joint. The center branch features a 1/2 inch outlet, enabling streamlined integration with smaller branch lines for zone feeds, fixture supply drops, or system extensions.

Applications

• ✔ Domestic hot and cold water lines
• ✔ Hydronic heating systems
• ✔ Low-pressure air or vacuum lines (non-industrial)

Advantages in the Field

• ✅ Dimensional Accuracy: Engineered for uniform wall thickness and socket depth for predictable solder fill
• ✅ Corrosion Resistance: Copper is naturally resistant to biofilm growth and chemical degradation
• ✅ Time Savings: Eliminates the need for additional bushings or reducers at branch lines

Code Compliance

This fitting meets requirements for lead-free installation under the Safe Drinking Water Act (SDWA) and is approved for use by IPC and UPC plumbing codes. It is suitable for use in both horizontal and vertical installations, and is compatible with Type L, M, and DWV copper tubing as applicable to the system’s function.

Note:

Ensure compatibility between copper tube size (CTS) dimensions and fitting size before installation. Use only soldering materials that comply with ASTM B813 for potable water systems.

Designed for long service life with minimal maintenance, the 1-1/4 inch x 1/2 inch x 1-1/4 inch Copper Reducing Tee is a dependable solution for contractors managing distribution system transitions in tight or concealed framing spaces. It offers precise fitment, meets all modern code requirements, and contributes to the integrity of both residential and commercial plumbing systems.
