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

1-1/2 inch x 1-1/4 inch Copper Reducing Coupling – Wrot Copper, C x C

The 1-1/2 inch x 1-1/4 inch copper reducing coupling is a solder joint (C x C) fitting used for joining copper tubing of different diameters in a straight-run configuration. Manufactured from lead-free wrot copper, this fitting meets ASTM and ANSI standards for use in potable water, hydronic, and mechanical piping systems.

Engineered to provide a consistent solder connection, this coupling is commonly specified for size transitions in pressurized copper piping networks. The fitting is compatible with Type K, L, or M copper tubing and is suitable for horizontal or vertical installations in commercial and residential systems.

Product Features

• ✅ Nominal Sizes: 1-1/2 inch run x 1-1/4 inch run
• ✅ Connection Type: Copper x Copper – sweat (solder) joint for brazed or soft-soldered applications
• ✅ Material: Wrot copper alloy (typically UNS C12200), lead-free formulation
• ✅ Compliance: NSF/ANSI 61 and NSF/ANSI 372 certified for potable water systems
• ✅ Standard: Conforms to ASME B16.22 and ASTM B75/B88 specifications

Installation Notes

Install by preparing tubing ends with appropriate cleaning, flux, and heat. Insert tubing to the full socket depth and heat the joint evenly before applying solder. Proper cooling and inspection are required. The fitting is compatible with copper tubing systems operating under standard pressure and temperature ranges per IPC/UPC code requirements.

Typical Applications

Used in potable water supply lines, hydronic heating circuits, and mechanical piping systems where a size reduction is needed without offsetting the pipeline. Suitable for both new construction and retrofit work in residential, commercial, or institutional buildings.

Regulatory Compliance

Lead-free copper fittings are required for potable water applications in accordance with the U.S. Safe Drinking Water Act (SDWA). This fitting is listed for code-compliant use in all 50 states and is third-party certified for safety and material integrity.
