1-1/2 inch x 1 inch Copper Reducing Coupling – Seamless Solder Joint Fitting for Water Distribution Systems

The 1-1/2 inch x 1 inch Copper Reducing Coupling is designed to connect copper tubing of different diameters in pressurized potable water, HVAC, and hydronic applications. Manufactured from high-grade, lead-free copper, this coupling supports code-compliant installations requiring reliable performance and corrosion resistance.

Fabricated in accordance with ASME B16.22 and ASTM B75/B88 standards, the coupling provides a seamless connection using sweat/solder joining methods. Its precision-formed socket ends ensure a tight capillary fit, which when properly installed, yields a durable, leak-resistant joint suitable for both residential and commercial systems.

Product Features

• Material: Lead-free wrought copper (≤0.25% lead content)
• Nominal Sizes: 1-1/2 inch x 1 inch
• Connection Type: Female socket (cup) ends for soldering
• Standard Compliance: ASME B16.22, NSF/ANSI 61 & 372, ASTM B75/B88

Advantages for Contractors

• Dimensional Accuracy: Machined to strict tolerances for consistent fit and repeatable installation outcomes.
• Mechanical Strength: Engineered to withstand thermal expansion and internal system pressure in typical hot and cold water applications.
• Corrosion Resistance: Copper alloy resists dezincification and internal scaling, extending service life.
• Code Compatibility: Suitable for use in systems governed by IPC, UPC, and applicable mechanical codes requiring lead-free components.

Installation Guidance

For proper installation, ensure pipe ends are clean and deburred. Use approved lead-free solder and flux. Heat evenly to draw solder into the joint through capillary action. Allow cooling before pressure testing. Always follow applicable codes and manufacturer guidance for flame safety and joint prep. Use in accordance with local authority approvals for potable water or heating lines.

Common Applications

This reducing coupling is used in type L and M copper piping systems for potable water lines, radiant heat circuits, chilled water distribution, and process piping where a reduction in pipe diameter is required.

Code Note

All potable water system components must comply with federal lead-free legislation (Safe Drinking Water Act, Section 1417). This coupling meets those requirements under NSF/ANSI 61 and 372.

The 1-1/2 inch x 1 inch Copper Reducing Coupling delivers high-integrity performance for critical piping transitions. Preferred by mechanical and plumbing professionals for its reliable joint strength and longevity, it's a fitting designed to meet rigorous jobsite demands.
