3/8 inch ID Copper Refrig 90 Degree Long Radius Street Elbow Copper x Fitting

3/8 inch x 1/2 inch Copper Refrigeration Elbow – Precision-Formed for HVAC and Mechanical Piping Systems

The 3/8 inch x 1/2 inch Copper Refrigeration Elbow is a precision-formed wrought copper fitting engineered to transition tubing direction in refrigeration and HVAC line sets. Featuring sweat connections on both ends, this elbow provides a compact 90-degree bend for tight installations while maintaining flow characteristics and minimizing turbulence.

Manufactured from high-purity, lead-free copper, this fitting meets ASME B16.22 specifications and is NSF/ANSI 61 certified for potable water applications. It is suitable for use in low- and medium-pressure refrigeration systems, particularly those using R-22, R-410A, or similar refrigerants in accordance with industry standards.

Advantages for System Designers and Installers

• ✅ Accurate Dimensional Tolerance Ensures precise alignment and clean brazed joints
• ✅ Thermal and Pressure Efficiency Made from Type L copper for optimal conductivity and strength
• ✅ Reduced Field Labor Street-compatible profile simplifies layout and reduces extra coupling requirements
• ✅ Corrosion-Resistant Offers extended service life in refrigeration environments exposed to moisture and pressure cycles
• ✅ Code-Compliant Listed for use under major U.S. mechanical and plumbing codes

Technical Specifications

• Material: Lead-free wrought copper (ASTM B75/B88)
• Size: 3/8 inch x 1/2 inch nominal tubing
• Connection Type: Copper x Copper (sweat/solder joint)
• Bend Angle: 90 degrees
• Certification: NSF/ANSI 61, ASME B16.22

Application Scope

This elbow is commonly used in refrigerant line sets, chiller systems, evaporator coil routing, and other HVACR applications requiring directional changes in copper tubing. It is also applicable in hydronic systems and general mechanical installations where compact geometry is required for routing efficiency.

Industry Note

Copper elbows in refrigeration applications must be brazed using an appropriate alloy (typically AWS BCuP-5 or BAg brazing alloys) and purged with inert gas to prevent internal oxidation and scale formation. This ensures long-term integrity and system cleanliness.

Installation Guidance

This component is intended for use by trained personnel experienced in copper tube installation. For optimal results, clean all mating surfaces, apply flux where necessary, and follow standard brazing practices. Always pressure-test the assembly per project specifications and applicable codes after installation.

Conclusion

The 3/8 inch x 1/2 inch Copper Refrigeration Elbow offers a dependable solution for HVAC contractors requiring a compact, high-integrity fitting for directional transitions in pressurized copper systems. Built to meet the stringent demands of mechanical applications, it ensures a professional result with every install.
