1-1/4 inch Copper 90 Degree Elbow Copper x Copper

1-1/4” Copper 90° Elbow – Wrought Copper Solder Fitting for Directional Change

The 1-1/4” copper 90-degree elbow is a solder-joint fitting used to make a right-angle change in direction within copper piping systems. Designed for use with hard-drawn or annealed copper tubing, this fitting is commonly used in potable water distribution, hydronic heating systems, and mechanical piping applications requiring precise directional control.

Manufactured from lead-free wrought copper (ASTM B75 Alloy C12200), this elbow meets applicable standards for solder joint pressure fittings and complies with national plumbing codes for potable water systems. The fitting is compatible with Type L and Type M copper tubing and is suitable for above-ground applications.

Technical Specifications

• Nominal Size: 1-1/4 inch
• Connection Type: Solder Cup x Solder Cup
• Material: Lead-Free Wrought Copper, Alloy C12200
• Compliance: ASME B16.22, NSF/ANSI 61 & 372 (lead-free), ASTM B75
• Pressure Rating: Up to 200 PSI (non-shock, when properly installed)
• Maximum Service Temperature: 400°F (dependent on solder alloy)

Key Features

• ✅ 90° Flow Transition – Creates a right-angle directional shift for water or hydronic flow with minimal head loss
• ✅ Lead-Free Certification – Conforms to Safe Drinking Water Act standards for potable systems in all U.S. jurisdictions
• ✅ Corrosion-Resistant Copper – Compatible with a wide range of water chemistry and system types
• ✅ Seamless Integration – Engineered to fit standard copper tube dimensions for Type L and M systems

Installation Guidance

To install, clean and flux the pipe and fitting ends, then join using a lead-free solder alloy and a heat source compliant with code. Avoid overheating, and allow sufficient cooling time prior to pressurizing the system. This elbow is not designed for press-fit or threaded connections and should only be used in soldered assemblies.

Typical Applications

Commonly used in residential and commercial hot and cold water supply systems, heating loops, and HVAC piping where 90-degree directional changes are required in horizontal or vertical layouts. It is also suitable for DWV transitions where soldered copper assemblies are permitted by code.

Material Note

Copper remains the preferred material for soldered potable water systems due to its strength, temperature tolerance, and proven long-term performance. All fittings conforming to ASME B16.22 provide uniformity in joint integrity and dimensional compatibility across systems.

The 1-1/4” copper 90-degree elbow is a critical component in soldered piping assemblies, offering mechanical strength, corrosion resistance, and compliance with modern lead-free requirements for safe potable water delivery.
