1/2 inch Copper Street 45 Degree Elbow Copper x Fitting

1/2 inch Copper Street 45° Elbow – Sweat x Cup Fitting for Directional Transitions

The 1/2 inch Copper Street 45-Degree Elbow is a forged copper fitting used to change the direction of copper tubing runs in potable water and hydronic heating systems. Featuring a street (male) sweat end on one side and a female socket (cup) on the other, this elbow allows for direct insertion into another fitting without the need for an additional coupling.

Fabricated from lead-free wrought copper alloy, this fitting meets national plumbing code requirements for use in potable water systems. Its 45° bend angle provides a smooth directional transition with reduced flow resistance compared to more acute fittings, making it suitable for confined spaces or system layout optimization.

Performance Characteristics

• ✅ Material: Lead-free wrought copper (typically alloy C12200)
• ✅ Angle: 45-degree bend for gradual direction change in copper piping
• ✅ End Connections: Male sweat x Female socket – fits directly into standard copper fittings
• ✅ Compatibility: Designed for use with ASTM B88 Type L and M copper tube
• ✅ Pressure Rating: Suitable for systems rated up to 200 PSI and 400°F, depending on soldering method and pipe type

Technical Specifications

• Nominal Size: 1/2 inch
• Type: Street Elbow – 45°
• Connection Method: Solder (sweat) joint
• Applicable Standards: ASME B16.22, NSF/ANSI 61 & 372 (lead-free compliance), and UPC listing for potable water systems

Common Applications

Used in both residential and commercial copper tube installations for water supply lines, radiant heating loops, and cooling systems. The street-end configuration reduces fitting count and simplifies connections where space or alignment is a concern, such as at wall penetrations or equipment hookups.

Installation Notes

Install using industry-standard soldering techniques. Ensure pipe and fitting are cleaned and properly fluxed before soldering. Heat evenly and apply lead-free solder to joint per manufacturer and code instructions. Allow proper cooling before pressure testing.

The 1/2 inch Copper Street 45° Elbow offers code-compliant directional adjustment in copper systems while minimizing joint complexity. Its street-end design improves efficiency in space-limited assemblies and contributes to long-term system integrity when installed correctly.
