1 inch x 3/4 inch Copper Reducing Adapter – Solder Joint Fitting for Potable Water and Hydronic Applications

The 1 inch x 3/4 inch Copper Reducing Adapter is a sweat (solder) fitting used to transition between two different nominal pipe sizes in copper piping systems. Manufactured from lead-free wrought copper, this adapter is suitable for potable water distribution, chilled water, and hydronic heating systems requiring dimensional reduction with code-compliant materials.

Designed for permanent connections using lead-free solder, the adapter provides a clean, secure joint between copper tube sections, helping maintain flow integrity while accommodating space constraints and fixture transition points in the system layout.

Product Features

• ✅ Material: Lead-free wrought copper conforming to ASTM B75/B88 (typically alloy C12200).
• ✅ Connection Type: Female solder cup (1 inch) x male copper tube size (3/4 inch).
• ✅ Manufacturing Standards: Fabricated in compliance with ASME B16.22 for solder-joint copper fittings.
• ✅ Lead-Free Certified: Meets NSF/ANSI 61 and 372 standards for use in potable water systems.
• ✅ Durability: Suitable for pressure and non-pressure applications with typical service temperatures up to 400°F (depending on solder alloy).

Installation Guidelines

Install using approved lead-free solder and flux. Surfaces must be cleaned and properly prepped with emery cloth and fitting brush. Ensure proper fit-up and uniform heat distribution during soldering to achieve capillary flow. Use appropriate safety precautions when working with open flame in occupied or concealed spaces. Adhere to local plumbing codes and manufacturer instructions for installation torque and spacing.

System Applications

Used in potable water supply systems, hydronic heating circuits, and mechanical room piping layouts. Common in new construction, remodels, and repair scenarios where downsizing a run is required to accommodate fixture branches, valve connections, or appliance tie-ins.

Regulatory Compliance

This copper fitting complies with lead-free plumbing legislation under the Safe Drinking Water Act (SDWA) and is suitable for installations requiring certified materials for health and safety. Verification of local code alignment is recommended during specification.
