1-1/4 inch x 1 inch Copper Reducing Coupling Copper x Copper

1-1/4” x 1” Copper Reducing Coupling – Designed for Reliable Transitions

This copper reducing coupling is fabricated for transitioning between 1-1/4” and 1” Type L or M copper tubing in pressurized water distribution systems. Its uniform interior surface and close-tolerance design enable optimal flow characteristics and consistent joint integrity when properly installed using soldering techniques.

Formed from high-purity copper, this fitting meets current plumbing code requirements for lead-free systems. It is suitable for both new construction and retrofit installations across potable water, hydronic heating, and chilled water applications.

Performance Highlights

• ✅ Seamless Copper Construction Milled from wrought copper for enhanced pressure resistance and long-term reliability.
• ✅ Dimensional Consistency Machined to ANSI/ASME B16.22 standards for a tight, uniform fit in brazed or soldered joints.
• ✅ Flow Optimization Reducing design supports consistent hydraulic transition with minimal turbulence.
• ✅ Code Compliance Conforms to NSF/ANSI 61 and 372 for use in lead-free potable systems.

Specification Data

• Size: 1-1/4” x 1” nominal copper tubing
• Material: Wrought copper (≥99.9% Cu)
• Connection Type: C x C (sweat/solder)
• Certifications: NSF/ANSI 61 & 372 certified, meets ASTM B75 and B16.22

Installation Notes

Compatible with standard copper tube and fittings for soldered or brazed connections. Surfaces should be cleaned and fluxed prior to joining. Heating must be uniform and controlled to prevent overheating. Professional installation ensures consistent bond strength and minimizes potential for leaks or inspection failure.

Use Cases

Frequently installed in domestic water supply lines, mechanical piping systems, and heating loops where pipe diameter transitions are required. Its use is typical in slab rough-ins, mechanical rooms, and vertical risers in both residential and commercial systems.

Industry Update

All potable water fittings must meet lead-free mandates under the Reduction of Lead in Drinking Water Act. This coupling is manufactured in compliance with those requirements and is accepted for use nationwide in municipal and private water systems.

Professional-grade fittings like this copper reducer support performance consistency and long-term system reliability. Specify it where pressure ratings, inspection readiness, and uniformity of construction are critical to the job.
