3 inch Copper Street 90 Degree Elbow Copper x Fitting

3 inch Copper Street 90° Elbow – Solder Joint Fitting for Pressure and Drainage Systems

The 3 inch Copper Street 90° Elbow is a wrought copper fitting designed to provide a 90-degree directional change between copper tube and fitting hub connections. One end is a male (street) sweat connection that fits directly into another copper fitting, while the other is a female sweat end for copper tube insertion. This configuration allows for space-efficient turns in piping layouts while maintaining flow alignment and system integrity.

Manufactured from lead-free copper and conforming to ASME B16.22 standards, the elbow is suitable for use in potable water distribution systems, hydronic heating applications, and drainage installations that require soldered joints. The fitting meets NSF/ANSI 61 and 372 certifications for lead content compliance in drinking water systems.

Technical Specifications

• Nominal Size: 3 inches
• Material: Wrought Copper, Alloy C12200
• Fitting Type: 90° Street Elbow
• Connection Type: Male Sweat x Female Sweat (Cup x Street)
• Standards: ASME B16.22, ASTM B75/B88, NSF/ANSI 61 & 372 (Lead-Free)
• Application: Pressure and drainage copper piping systems

Installation Guidelines

Prepare both tube and fitting surfaces using abrasive cloth or a wire brush. Apply lead-free soldering flux, then heat the joint evenly with an appropriate torch. Introduce lead-free solder once the flux reaches activation temperature to create a full circumferential bond. Follow all local and national codes for pressure testing, support spacing, and allowable joint configurations.

Typical Applications

Used in horizontal and vertical transitions within water supply lines, mechanical equipment hookups, hydronic loops, and sanitary drainage systems. Ideal for compact installations where one end of the fitting must be inserted directly into another copper fitting to reduce joint count and save space.

Material Insight

Wrought copper offers high corrosion resistance, excellent thermal performance, and long-term structural reliability. Street elbows reduce the need for additional couplings and are commonly specified in high-density mechanical systems or confined service chases.
