3/4 inch Copper 90 Degree Elbow Copper x Copper (Pack of 25)

3/4 inch Copper 90-Degree Elbow – Wrot Copper Fitting for Soldered Water Supply Systems

The 3/4 inch Copper 90-Degree Elbow is engineered for directional changes in copper tube systems carrying potable water, hydronic heating, and other pressurized fluids. Constructed from lead-free wrot copper, this fitting allows for clean 90-degree turns while maintaining system flow integrity and minimizing turbulence at directional transitions.

Designed in compliance with ASME B16.22 and manufactured under ASTM B75 or B88 standards, this elbow provides a precise socket fit for copper tube types L and M. It is suitable for soldered joint assemblies and meets federal lead-free requirements under NSF/ANSI 61 and 372, making it acceptable for use in all jurisdictions requiring low-lead components in potable systems.

Key Features

• Nominal Size: 3/4 inch
• Connection Type: Female socket x female socket (sweat)
• Material: Lead-free wrot copper (≤0.25% lead content)
• Angle: 90 degrees
• Applicable Tube Types: Copper tube types L, M, and DWV
• Certifications: NSF/ANSI 61 & 372, ASME B16.22 compliant

Application Areas

This elbow is commonly installed in hot and cold domestic water systems, chilled water loops, and HVAC hydronic lines. It is also suitable for use in drainage, waste, and vent (DWV) piping where soldered copper is required. The compact design and high corrosion resistance make it ideal for both new construction and retrofit scenarios, especially where space constraints require a tight radius turn.

Installation Guidelines

Ensure pipe ends are properly cleaned and deburred prior to assembly. Use approved flux and lead-free solder to achieve a reliable capillary joint. Heat should be applied evenly to the fitting and tube to draw solder fully into the joint. Follow applicable local codes and safety practices when working with open flame and pressurized systems.

Industry Insight

Wrot copper fittings are widely preferred in professional plumbing applications due to their durability, consistent tolerances, and ability to form reliable joints under variable thermal and mechanical stresses. The use of lead-free copper is now mandated for all potable water applications across the United States under the Safe Drinking Water Act.

The 3/4 inch Copper 90-Degree Elbow offers long-term performance in demanding environments, making it a staple component in code-compliant, high-integrity plumbing systems. Its strength, reliability, and compatibility with standard installation practices make it a dependable choice for professionals.
