2 inch Copper Reducing Adapter Copper x Female

2 inch x 1-1/2 inch Copper Reducing Adapter – Solder Joint Transition Fitting

The 2 inch x 1-1/2 inch Copper Reducing Adapter is designed to facilitate a direct reduction between two copper tube sizes in potable water, hydronic heating, or similar piping systems. Fabricated from lead-free wrought copper alloy, this fitting offers a secure solder-joint connection between a 2-inch nominal pipe and a 1-1/2 inch female-end termination.

Its construction complies with ANSI/ASME B16.22 and ASTM B75 standards, ensuring dimensional consistency and corrosion resistance in code-compliant plumbing systems. This adapter is suitable for use in Type L and Type M copper tubing applications where compact, permanent reductions are required.

Product Performance Attributes

• ✅ Material Composition: Lead-free copper alloy for potable water system compatibility.
• ✅ Connection Type: 2 inch copper tube x 1-1/2 inch female fitting – solder connection at both ends.
• ✅ Operating Temperature: Suitable for use in systems with sustained temperatures up to 400°F (204°C) when installed with lead-free solder alloys.
• ✅ Pressure Rating: Up to 200 PSI in water distribution systems, dependent on solder alloy and installation quality.
• ✅ Compliance: Conforms to NSF/ANSI 61 and NSF/ANSI 372 for lead-free plumbing components.

Installation Guidance

Installers must follow accepted soldering practices, including thorough cleaning of mating surfaces, application of lead-free flux, and appropriate heating to ensure full capillary action within the joint. Proper support of the piping system is required during and after installation to maintain alignment and joint integrity. This component is intended for use by trained personnel familiar with copper joining methods.

Application Scope

Commonly used in municipal water distribution systems, hydronic heating circuits, and recirculating domestic hot water applications, the 2 inch x 1-1/2 inch copper reducing adapter enables precise pipe size transitions without additional couplings. It is particularly valuable in retrofit scenarios where legacy piping diameters must be reduced for system modifications.

Technical Insight

Copper's non-reactive nature and antimicrobial properties make it the material of choice for pressurized domestic water systems. This reducing adapter preserves system flow rates while allowing for downstream piping reconfiguration in confined or existing installations.
