1-1/4 Inch x 1 Inch Copper Press Reducing Coupling – Lead-Free

The 1-1/4" x 1" Copper Press Reducing Coupling provides a reliable transition between dissimilar copper pipe sizes in potable water and hydronic systems. Designed for flame-free installation, this press coupling offers a secure mechanical joint using approved pressing tools, improving safety and reducing labor time on site.

Application-Driven Design

This coupling is precision-formed to ensure proper engagement with standard ASTM B88 copper tubing (Types L and M) and maintains consistent pressure ratings across typical water distribution systems. It is commonly used in piping layouts requiring size reductions while maintaining flow efficiency and minimizing turbulence.

• ✅ Mechanical Press Connection Compatible with most V-profile press systems for efficient, solder-free installation.
• ✅ Lead-Free Copper Conforms to NSF/ANSI 61 and 372 for use in potable water systems across all U.S. jurisdictions.
• ✅ Clean Fit & Flow Internal diameter transitions are optimized to maintain laminar flow through reduced pipe diameters.

Installation Considerations

Installation requires pipe cleaning, depth marking, and pressing with manufacturer-approved tools. No flux, solder, or open flame is necessary. Proper alignment and visual verification of press markings are recommended to ensure leak-free operation. This coupling is not designed for underground burial without protective provisions and should not be used in gas or fuel systems.

Technical Specifications

• Material: Lead-Free Copper (Dezincification-Resistant)
• Size: 1-1/4" x 1"
• Connection Type: Press x Press
• Pressure Rating: Up to 200 PSI (verify with system requirements)
• Certifications: NSF/ANSI 61 & 372, ASME B16.51, suitable for potable water and hydronic applications

Typical Use Cases

This reducing press coupling is commonly installed in residential, commercial, and institutional piping systems where copper size transitions are required. It is especially useful in mechanical rooms, risers, or branch lines where space constraints or prefabrication needs dictate mechanical joints over soldered connections.

Regulatory Insight

All press fittings for use in potable water must be manufactured from materials that meet federal lead-free mandates under the Safe Drinking Water Act. This coupling meets those requirements and is approved for use in all 50 states.

The 1-1/4" x 1" Copper Press Reducing Coupling delivers consistent performance and reliability for size transition joints in high-demand plumbing systems. Designed for speed, compliance, and long-term durability in modern mechanical installations.
