1-1/4 inch x 1/2 inch Copper Reducing Coupling with Stop Copper x Copper

1-1/4 inch x 1/2 inch Copper Reducing Coupling – Engineered for Secure Transitions

The 1-1/4 inch x 1/2 inch Copper Reducing Coupling is a precision-formed fitting used to join copper tubing of dissimilar diameters in pressure and drainage systems. Manufactured from lead-free copper, this coupling offers a durable solution for reliable performance in code-compliant potable water and mechanical piping applications.

Its smooth internal diameter and uniform wall thickness promote consistent flow, while its dimensional accuracy supports secure soldered connections that meet inspection requirements. The coupling is suited for both new construction and retrofit installations where space and alignment tolerances are critical.

Performance Features

• ✅ High-Precision Machining – Ensures a uniform fit with copper tubing for leak-resistant joints.
• ✅ Corrosion-Resistant Copper Alloy – Withstands exposure to typical water chemistry and environmental conditions.
• ✅ Full-Length Socket Engagement – Provides maximum surface contact to enhance solder bond integrity.

Key Attributes

• ✅ Compact Footprint – Ideal for installations in confined spaces, wall cavities, and mechanical chases.
• ✅ Versatile Application – Used in domestic water distribution, HVAC piping, and pressure-rated service lines.
• ✅ Lead-Free Compliance – Meets all national requirements for use in potable water systems.

Installation Guidance

This coupling is designed for sweat installation. Prepare pipe ends by cleaning and reaming, apply approved flux, and use even torch heat for full capillary action. Threaded sealing materials are not applicable for solder joints. For optimal results, pressure-test the system after installation in accordance with local code.

Common Use Cases

Typically used in water supply transitions from larger to smaller diameter copper lines. The 1-1/4 inch x 1/2 inch configuration is particularly useful in remodels, branch reductions, and retrofit scenarios where adapting existing pipe runs is required. Also applicable in DWV configurations where space and alignment demand a flush, compact reduction fitting.

Compliance Note

Lead-free copper fittings are mandated by plumbing codes nationwide for use in potable water systems. This product complies with ANSI/NSF 61-G and other applicable certifications.

The 1-1/4 inch x 1/2 inch Copper Reducing Coupling delivers a dependable, code-compliant solution for high-integrity copper piping systems. Built to perform under pressure and engineered for precision, it remains a standard choice for professionals seeking quality and long-term reliability in pipe size transitions.
