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

1-1/2 Inch x 1 Inch Copper Press Reducing Coupling – Lead-Free, NSF 61 Certified

The 1-1/2 inch x 1 inch copper press reducing coupling is designed for use in potable water and hydronic systems requiring a transition between two different pipe sizes. It features press-fit ends for permanent, mechanical connections to copper tube, eliminating the need for soldering or open flame. This fitting supports system design flexibility and meets applicable plumbing and mechanical codes.

Standards and Material Compliance

This press reducing coupling is manufactured from lead-free wrought copper and meets the dimensional and material specifications of ASME B16.51. The press ends are compatible with standard press tools and V-profile jaws. Sealing is achieved through an EPDM elastomeric sealing element rated for potable water and heating applications. Certified for use in domestic water systems under NSF/ANSI 61 and NSF/ANSI 372.

• ✅ Material: Lead-free copper (typically UNS C12200)
• ✅ Connection Type: Press x Press (reduced outlet)
• ✅ Sealing Element: EPDM O-ring, factory-installed
• ✅ Compliance: NSF/ANSI 61 & 372, ASME B16.51, IAPMO listed

Technical Specifications

• Size: 1-1/2 inch x 1 inch nominal
• Pressure Rating: Up to 200 psi (water, air, or inert gas)
• Temperature Rating: 0°F to 250°F (EPDM-dependent)
• Applications: Potable water, chilled water, hydronic heating, and HVAC systems

Installation Requirements

Install using manufacturer-approved press tools and jaws. Pipe must be cut square, reamed, deburred, and marked for insertion depth. Fitting must be fully seated before pressing. Press connections should be leak-tested according to local codes and system specifications. Do not use for steam or fuel gas applications unless rated accordingly by the manufacturer.

Typical Use Cases

Commonly used in multi-size copper distribution systems in residential, commercial, and institutional plumbing layouts. Ideal for pressure-rated installations where a reduction in line size is required and soldering is not practical due to jobsite constraints or fire-safety requirements.

Code Compliance Note

Lead-free fittings are required in potable water systems in accordance with the Safe Drinking Water Act. This press coupling meets federal and state requirements and is suitable for use in IPC and UPC jurisdictions.
