1-1/4 inch x 3/4 inch Copper Reducing Adapter Male x Copper

3/4 inch x 1-1/4 inch Copper Reducing Adapter – Lead-Free, Code-Compliant Fitting

The 3/4 inch x 1-1/4 inch copper reducing adapter is a sweat connection fitting designed to transition between copper tube sizes in pressure or potable water systems. It conforms to modern code requirements by using lead-free copper, ensuring suitability for residential and commercial installations where safe drinking water standards must be met.

Product Characteristics

• Material: C12200 copper (lead-free, ASTM B75)
• Configuration: Reducing male adapter – 3/4 inch nominal male sweat x 1-1/4 inch nominal female sweat
• Pressure Rating: Suitable for use in systems up to 200 psi at 73°F (dependent on pipe schedule and solder type)
• Connection Method: Solder (sweat) connections for both inlet and outlet ends
• Standards: Manufactured in accordance with ANSI/NSF 61, NSF 372 (lead-free), and ASME B16.22

Performance and Advantages

• Precision Fit: Machined and formed to close tolerances for reliable soldering and mechanical integrity
• System Compatibility: Compatible with Type K, L, and M copper tubing for both hot and cold water applications
• Corrosion Resistance: Copper provides excellent resistance to dezincification, pitting, and scaling in potable systems
• Compliance Ready: Certified for use in lead-free installations as mandated by the Safe Drinking Water Act and Uniform Plumbing Code

Installation Considerations

Before soldering, all surfaces must be cleaned and fluxed using an appropriate lead-free soldering compound. Ensure the joint is fully seated and adequately heated for a full capillary seal. Use caution to prevent excessive heat that may compromise nearby fittings. For vertical and overhead joints, secure alignment prior to assembly to maintain flow orientation and support integrity.

Common Applications

This reducing adapter is used in water supply systems, hydronic heating lines, and branch circuits where pipe size transitions are required. It is often installed in retrofit projects, mechanical rooms, or equipment connections such as boilers and tanks.

Note on Compliance

Federal and state plumbing codes now require the use of certified lead-free components in potable water systems. This adapter is fully compliant with current requirements for drinking water system components and is approved for use in all 50 U.S. states.

Engineered for consistent fit and pressure performance, the 3/4 inch x 1-1/4 inch copper reducing adapter offers a dependable solution for copper-to-copper transitions in modern plumbing infrastructure.
