3/8 inch Copper 90° Elbow – Wrought Fitting for Sweat Applications

The 3/8 inch Copper 90 Degree Elbow is a precision-formed wrought copper fitting used to create right-angle changes in direction within Type K, L, or M copper tubing systems. Commonly installed in water supply, hydronic heating, and refrigeration lines, this elbow supports clean, efficient directional transitions in compact piping layouts.

Manufacturing and Material Properties

Fabricated from lead-free alloy C12200 (deoxidized high-phosphorus copper), this elbow exhibits excellent thermal conductivity, corrosion resistance, and brazing characteristics. Its seamless construction ensures long-term mechanical integrity under varying pressure and temperature loads.

Technical Specifications

• Material: Wrought Copper (Alloy C12200, lead-free)
• Size: 3/8 inch nominal
• Connection Type: Copper tube (sweat/solder connection, socket x socket)
• Fitting Angle: 90 degrees
• Pressure Rating: Suitable for up to 200 psi at 250°F (varies by system)
• Standard Compliance: ASME B16.22, NSF/ANSI 61 & 372, ASTM B75/B88

Installation Considerations

This elbow is designed for soldered or brazed joints. Proper cleaning, fluxing, and heat application are essential to create a uniform, leak-free seal. Ensure compatibility with pipe size and type per system specifications. Use with potable water systems, chilled water, compressed air, or low-pressure steam, depending on design intent and code requirements.

Common Applications

Widely used in residential and light commercial projects, this 90° elbow facilitates compact turning in copper tubing within wall cavities, ceiling voids, or equipment enclosures. It is often installed in bathroom risers, water heater branches, and distribution manifolds requiring directional transitions with minimal turbulence.

Industry Note

All copper fittings intended for potable water must now meet lead-free requirements per the Safe Drinking Water Act. This fitting complies with these regulations, offering full compatibility in regulated domestic water systems.
