1-1/2 inch x 3/4 inch Brass Reducing Tee Copper x Copper x Female

1-1/2 inch x 3/4 inch Lead-Free Brass Reducing Tee – Commercial Grade for High-Integrity Systems

The 1-1/2 inch x 3/4 inch lead-free brass reducing tee is manufactured for dependable branch line transitions in pressurized systems. Constructed from corrosion-resistant, dezincification-resistant brass alloy, this fitting offers long-term performance in potable water, air, and non-corrosive fluid applications. The female NPT threads provide secure compatibility across a range of system designs.

This tee enables reduction from a 1-1/2 inch main line to a 3/4 inch branch, minimizing turbulence and preserving hydraulic performance. Suitable for both vertical and horizontal installations, it meets NSF/ANSI 61 and 372 standards for lead-free compliance in potable water systems and is tested for conformity with national mechanical and plumbing codes.

Product Performance and Benefits

• ✅ Lead-Free Brass – Conforms to federal and state regulations for potable water systems.
• ✅ Threaded FNPT Connections – Compatible with Schedule 40/80 pipe and most threaded metal piping.
• ✅ Machined to Tight Tolerances – Provides strong, vibration-resistant seals when installed with approved thread sealants.
• ✅ Temperature and Pressure Ratings – Typically rated to 200 PSI and 400°F (check manufacturer data).

Technical Specifications

Installation Notes

Use a certified thread sealant or PTFE tape suitable for potable water. Avoid overtightening, particularly in brass-to-brass joints, to prevent thread damage. Ensure system is depressurized during installation. Install according to IPC or UPC code as applicable to the project jurisdiction.

Typical Use Cases

Ideal for installation in copper or brass-based plumbing systems requiring a transition from a 1-1/2 inch supply line to a 3/4 inch outlet, commonly found in commercial build-outs, utility rooms, mechanical rooms, and branch supply lines in large residential or mixed-use developments.

Note

Verify compatibility with existing system materials and pressure ratings. Always follow job-specific specifications and local code requirements.
