1-1/4 inch x 1 inch Copper Reducing Adapter Male x Copper

1-1/4 inch Copper Reducing Adapter Male – For Transitioning Copper to Male Thread Connections

The 1-1/4 inch Copper Reducing Adapter Male is a precision fitting designed for joining copper tubing to male-threaded components in plumbing systems. Manufactured from lead-free copper, this adapter supports reliable transitions in pressure-rated and potable water applications. Its reduction profile is engineered to accommodate dimensional shifts without compromising hydraulic performance.

Field-Ready Features

Contractors rely on reducing adapters to simplify transitions between dissimilar fitting types and pipe sizes. This fitting is engineered to meet those requirements with consistent performance:

• ✅ Machined Male Threads NPT threads conform to ANSI B1.20.1 for uniform engagement and sealing compatibility.
• ✅ Lead-Free Copper Alloy C12200 meets NSF/ANSI 61 and 372 standards for potable water system use.
• ✅ Pressure-Capable Design Suitable for applications requiring high-pressure tolerance and joint integrity.
• ✅ Reduced Joint Count Provides a single-solution reduction and transition without added couplings or bushings.
• ✅ Consistent Sweat End Dimensions Fabricated to ASTM B75 and ASME B16.22 standards for reliable soldered joints.

Installation Considerations

Use of approved thread sealants or PTFE tape is recommended on the male thread for watertight sealing. Clean and flux the copper end thoroughly prior to soldering. Ensure the assembly is properly supported during installation to avoid thread damage or joint stress.

Applications

This fitting is commonly used in plumbing systems where a copper pipe must transition to a threaded valve, fixture, or mechanical connection point. Frequently applied in service entrance areas, distribution headers, and transitions between pipe systems of varying material or diameter.

Code Compliance Note

Lead-free copper fittings are mandated for all potable water applications per the Reduction of Lead in Drinking Water Act. This adapter conforms to applicable code requirements for safe use in drinking water and domestic systems.

The 1-1/4 inch Copper Reducing Adapter Male offers a field-tested solution for pipe-to-thread transitions, delivering secure, code-compliant performance in both new construction and retrofit environments. Its durable construction and dimensional consistency make it a reliable choice for professional-grade plumbing assemblies.
