1/2 inch x 1/8 inch Copper Flush Bushing Fitting x Female

1/2 inch x 1/8 inch Lead-Free Copper Reducing Bushing – Sweat x Sweat Fitting for Potable Water Systems

The 1/2 inch x 1/8 inch Lead-Free Copper Bushing is a solder-type reducing fitting designed to join copper tubing of different diameters in water distribution systems. Manufactured from lead-free wrought copper, it is engineered for use in non-pressurized and pressurized potable water lines and hydronic heating systems.

Compliant with NSF/ANSI 61 and 372 standards, this bushing enables a transition from 1/2 inch nominal copper tubing down to 1/8 inch, maintaining system integrity while meeting all applicable local and national plumbing codes regarding lead content in drinking water applications.

Product Specifications

• Nominal Sizes: 1/2 inch x 1/8 inch
• Material: Lead-free wrought copper (C12200 or equivalent)
• Connection Type: Sweat x Sweat (cup ends for soldering)
• Application: Potable water, chilled water, and hydronic heating systems
• Certifications: NSF/ANSI 61 & 372 compliant; ASTM B75/B88

Installation Guidelines

Surface preparation and proper soldering techniques are critical for leak-free performance. Clean both tubing and fitting surfaces using a certified cleaning brush or abrasive cloth. Apply approved flux and heat evenly before introducing lead-free solder to achieve full circumferential bonding. Follow manufacturer guidelines and applicable code requirements for installation spacing, support, and testing.

Common Applications

This reducing bushing is used in copper piping systems to downsize tubing diameters while maintaining continuous flow. It is typically found in water supply branches, valve connections, equipment tie-ins, and pressure regulation assemblies where reduced pipe sizing is required.

Material Insight

Lead-free copper fittings are mandated for use in potable systems throughout the United States. These fittings maintain long-term durability and corrosion resistance, making them a reliable choice in environments subject to fluctuating temperature and pressure conditions.
