1 inch x 3/4 inch x 3/4 inch Copper Reducing Tee – Lead-Free, Sweat Connection for Potable Water Systems

The 1 inch x 3/4 inch x 3/4 inch Copper Reducing Tee is a sweat-style fitting used to join three copper tube lines of varying diameters in potable water, hydronic heating, or low-pressure air systems. Manufactured from lead-free wrought copper, this tee supports code-compliant transitions between distribution lines and branch supplies, commonly in multi-zone plumbing or HVAC installations.

Its uniform wall thickness and consistent inside diameter help maintain system flow rates and pressure balance, while the reducing configuration allows for efficient downsizing within compact routing paths. This tee meets current requirements for lead-free installations as outlined under the Safe Drinking Water Act (SDWA).

Key Features

• ✅ ASTM B75/B88 Compliant – Produced to industry standards for use with Type L and M copper tubing.
• ✅ Lead-Free Alloy – Suitable for potable water service under NSF/ANSI 61 and 372 certifications.
• ✅ Precision Sizing – Sweat socket design ensures capillary action during soldering for reliable sealing.
• ✅ Pressure Rated – Suitable for residential or commercial hot and cold water systems up to 200 PSI and 180°F continuous service.

Technical Specifications

• Material: Lead-free wrought copper
• End Connections: Sweat (C x C x C)
• Size: 1 inch inlet x 3/4 inch outlet x 3/4 inch outlet
• Certification: NSF/ANSI 61 & 372, ASTM B75, B88, and B16.22

Installation Guidelines

This fitting must be installed using approved soldering methods per ASTM B828. Surfaces should be cleaned and fluxed before insertion and joined using appropriate lead-free solder. Post-solder cooling and flushing are required before pressurization. All joints should be tested in accordance with local plumbing codes and ANSI standards for leak verification.

Common Applications

This copper reducing tee is used primarily in potable water distribution networks and heating systems where reduced pipe diameters are necessary for flow balancing. It is appropriate for use in residential plumbing trunks, branch circuits in hydronic heating loops, and service risers in multi-unit buildings.

Code Compliance Note

Lead-free copper fittings are now a requirement for all potable systems under federal law. This tee is fully compliant with all applicable U.S. code standards for use in lead-free installations and municipal water supply systems.

The 1 inch x 3/4 inch x 3/4 inch Copper Reducing Tee provides a permanent, pressure-capable connection designed for optimal hydraulic efficiency and long-term corrosion resistance. It meets or exceeds performance standards for copper solder fittings in residential and commercial applications.
