1/2 inch x 3/8 inch Copper Flush Bushing Fitting x Copper

1/2 inch x 3/8 inch Copper Flush Bushing – For Reliable Size Reduction in Copper Systems

The 1/2 inch x 3/8 inch Copper Flush Bushing is designed for precise dimensional transitions in copper piping layouts. This fitting enables accurate reductions within water supply and hydronic systems while maintaining structural integrity and flow control. Its compact flush-mount profile is ideal for installations where space constraints or visual uniformity are required.

Constructed from high-quality, lead-free copper alloy, this bushing complies with national plumbing codes and is suited for use in potable water systems. It offers dependable performance in pressure and thermal applications, minimizing the potential for connection failure over time.

Performance Features

• ✅ Machined Accuracy – Tight tolerances promote clean seating and secure joints within fittings or valve assemblies.
• ✅ High-Strength Copper Alloy – Offers superior corrosion resistance and long service life in typical operating conditions.
• ✅ Thread Stability – Reduces the risk of seepage when installed with approved sealants in mixed metal systems.

Technical Specifications

• Nominal Size: 1/2 inch x 3/8 inch
• Material: Lead-Free Copper
• End Connection: Copper Sweat (Flush Insert)
• Certifications: Compliant with ANSI/NSF 61-G for potable water use
• Typical Applications: Plumbing and heating system transitions, valve inlet fittings, and fixture branches

Installation Notes

Installation requires proper pipe preparation and a clean seating surface. For soldered joints, ensure both the fitting and pipe end are cleaned, fluxed, and evenly heated to achieve full capillary penetration. Where threaded components are involved, apply compatible sealants such as PTFE tape or thread compound to achieve a pressure-tight seal. Always test completed systems per local code before commissioning.

Common Use Cases

This flush bushing is frequently specified in residential and light commercial projects where a 1/2 inch line must be reduced to 3/8 inch, particularly at valves, risers, and branch takeoffs. Its compact profile makes it suitable for use within confined enclosures or finished wall cavities.

Code Compliance

Lead-free copper fittings are required in potable water systems by federal mandate and adopted plumbing codes nationwide. This bushing meets those requirements for safe system integration.

The 1/2 inch x 3/8 inch Copper Flush Bushing is a professional-grade component engineered for reliability and precision. It supports long-term performance in pressure-rated systems and provides a clean, compact transition point between pipe diameters without compromising code compliance or flow integrity.
