1 inch x 3/4 inch Copper Reducing Tee – Wrought Copper Fitting for Soldered Transitions

The 1 inch x 3/4 inch Copper Reducing Tee is a solder joint fitting manufactured from high-grade, lead-free wrought copper (ASTM B75 Alloy C12200). It is designed to branch a 3/4 inch line off a 1 inch main, facilitating efficient changes in line diameter within copper piping systems carrying potable water, hydronic heating fluids, or low-pressure air.

Formed to precise dimensional tolerances in accordance with ASME B16.22, this tee supports uniform heat transfer and consistent capillary action during soldering. Its seamless construction ensures structural integrity under service conditions governed by applicable mechanical and plumbing codes.

Functional Attributes

• ✅ Material Specification: Wrought copper (C12200, DHP grade) for superior thermal conductivity and corrosion resistance.
• ✅ Joint Type: Solder cup connections on all three ends for brazing or soft-solder applications.
• ✅ Dimensional Compliance: Manufactured in accordance with ASME B16.22 for compatibility with standard tube sizing.
• ✅ Pressure and Temperature Ratings: Suitable for continuous operation in water systems up to 200 PSI and 400°F when properly joined and supported.
• ✅ Lead-Free Certification: Meets NSF/ANSI 61 and 372 for use in potable water systems under federal lead content restrictions.

Technical Specifications

• Material: Copper, ASTM B75 Alloy C12200
• Size: 1 inch x 3/4 inch x 1 inch
• Connection: Cup x Cup x Cup (Solder)
• Standards: ASME B16.22, NSF/ANSI 61 & 372 compliant

Installation Considerations

Proper installation requires pipe cleaning and preparation using a reamer, fitting brush, and flux. Heat should be applied evenly to promote solder flow into the joint gap. Adhere to local codes regarding minimum insertion depth, joint spacing, and support. For systems requiring brazing, ensure fittings are rated for elevated joining temperatures and that appropriate filler metal is used.

Typical Applications

Used extensively in potable water systems, hydronic loops, and HVAC branch circuits. Ideal for size reductions in vertical risers, manifold assemblies, and utility distribution piping. Compatible with both new construction and retrofit environments where copper tubing is used.

Regulatory Compliance

Required for use in potable water distribution systems under the Safe Drinking Water Act and compliant with U.S. and Canadian plumbing standards for lead-free components.
