1-1/2 inch x 1-1/4 inch Copper Press Reducing Coupling Press Fitting x Copper

1-1/2" x 1-1/4" Copper Press Reducing Coupling – Built for Secure Transitions

The 1-1/2" x 1-1/4" Copper Press Reducing Coupling is engineered for high-performance press-fit connections in copper piping systems. Manufactured to meet ASTM and ANSI standards, this fitting enables precise diameter reduction while maintaining a secure, leak-resistant seal for potable water and hydronic applications.

Product Advantages

• ✅ Press Connection Integrity – Designed for use with approved pressing tools, providing uniform force distribution and reliable sealing.
• ✅ Lead-Free Copper Alloy – Compliant with NSF/ANSI 61 and 372 for use in potable water systems nationwide.
• ✅ Dimensional Accuracy – Manufactured to tight tolerances to ensure proper engagement and system pressure retention.

Specifications

• Material: Lead-free wrought copper
• Size: 1-1/2" x 1-1/4" nominal
• Connection: Press x Press
• Compliance: Conforms to ASME B16.51 and MSS SP-104
• Applications: Suitable for Type K, L, and M hard copper tubing

Installation Guidance

This press coupling is installed using an industry-standard hydraulic or battery-operated press tool fitted with compatible jaws. Proper pipe preparation, including deburring and cleaning, is essential for ensuring a leak-free seal. No soldering or adhesives are required, making the coupling ideal for environments where open flame is prohibited.

Use Cases

Commonly used in hot and cold potable water distribution, chilled water systems, and low-pressure steam, this reducing coupling supports efficient pipe transitions in tight or constrained areas. It is frequently applied in both commercial and residential installations, particularly in system upgrades or layout adjustments.

Code Compliance Note

All copper press fittings for potable systems must meet the lead content limits set by the Reduction of Lead in Drinking Water Act, which this coupling satisfies through the use of lead-free alloy composition.

The 1-1/2" x 1-1/4" Copper Press Reducing Coupling offers a reliable, flame-free alternative to soldering, delivering consistent performance under pressure. Its rugged construction and compliance with plumbing standards make it a preferred choice for professional-grade installations.
