1-1/2 inch x 1/2 inch Copper Reducing Coupling – Sweat Fitting for Pipe Size Transition

The 1-1/2 inch x 1/2 inch Copper Reducing Coupling is a solder joint fitting used to connect copper tubing of dissimilar diameters. Manufactured from wrought copper in accordance with applicable ASTM standards, this fitting provides a smooth, consistent interior bore to ensure minimal pressure drop and laminar flow at transition points.

Engineered for use in pressurized water supply, hydronic heating, and low-pressure distribution systems, the coupling meets current code requirements for lead-free plumbing components under the Safe Drinking Water Act (SDWA). It is compatible with both Type L and Type M copper tubing.

Performance Characteristics

• ✅ Wrought Copper Construction Delivers dimensional consistency, thermal stability, and corrosion resistance in a wide range of system environments.
• ✅ Precision-Formed Socket Ends Sized to match tubing outside diameters per ASME/ANSI B16.22 specifications for a proper capillary fit.
• ✅ Lead-Free Compliance Meets NSF/ANSI 61 and 372 standards for potable water use nationwide.
• ✅ Application Range Suitable for use in water service lines, HVAC installations, and mechanical retrofit projects requiring a reduction in tube size.
• ✅ Uniform Wall Thickness Supports a reliable solder joint during brazing or sweating procedures.

Technical Specifications

• Nominal Sizes: 1-1/2 inch x 1/2 inch
• Material: Wrought Copper Alloy (lead-free)
• Connection Type: Sweat x Sweat (socket solder joint)
• Standards: ASME B16.22, ASTM B75/B88, NSF/ANSI 61 & 372

Installation Guidelines

Fitting and pipe ends must be cleaned and fluxed prior to assembly. Apply heat evenly to the joint area and introduce solder once the proper temperature is reached. After soldering, flush and pressure-test the system per local code before placing in service. Ensure tubing is properly supported to prevent mechanical stress on the joint.

Application Scope

This reducing coupling is frequently installed in branch supply lines, fixture drops, and pump manifolds where a step-down in pipe size is needed without compromising flow or mechanical integrity. Designed for use in residential, commercial, and light industrial piping systems.

Code and Safety Note

Copper reducing fittings must be third-party certified for potable systems. Verify all system components comply with relevant jurisdictional codes and application pressure ratings before installation.
