1-1/4 inch x 1 inch Copper Reducing 90° Elbow – For Directional Transitions in Piping Systems

The 1-1/4 inch x 1 inch copper reducing 90-degree elbow is designed to create a change in direction while transitioning between two different pipe sizes within copper tubing systems. This fitting is frequently used in potable water lines, hydronic heating loops, and HVAC installations where space constraints or layout requirements demand a smooth, corrosion-resistant directional change.

Product Applications and Benefits

• ✅ Reduces Line Diameter – Allows connection of 1-1/4 inch tubing to 1 inch tubing while maintaining consistent directional flow.
• ✅ 90-Degree Bend – Facilitates clean right-angle transitions in tight or confined areas without the need for additional fittings.
• ✅ Suitable for Soldered Joints – Sweat connections allow for a permanent, pressure-rated seal when properly installed.
• ✅ Code-Compliant – Meets ASTM B75/B88 standards and is lead-free per NSF/ANSI 61-G requirements for use in potable systems.

Material and Specification Details

• Material: Wrought copper (typically C12200 DHP) for enhanced thermal conductivity and corrosion resistance
• Size: 1-1/4 inch nominal inlet x 1 inch nominal outlet
• Bend Radius: 90-degree angle per ASME B16.22
• Connection Type: Sweat/solder (socket ends)
• Pressure Rating: Suitable for up to 200 psi with appropriate solder and installation technique

Installation Considerations

This reducing elbow requires proper preparation and soldering techniques. Tubing ends must be cleaned and reamed, and flux should be applied before heating the joint and introducing lead-free solder. All installations must be pressure tested in accordance with local codes. Use of the fitting in gas systems is not recommended unless specifically rated for such service.

Typical Use Cases

Commonly used in potable water distribution, chilled water systems, and low-pressure steam or condensate return piping. It is also suitable for use in closed-loop hydronic heating and snow-melt systems where directional changes and size reductions are required.

Additional Technical Information

Copper has inherent antimicrobial and corrosion-resistant properties, making it ideal for long-term use in plumbing systems where water quality and material longevity are critical. The reduced outlet allows downsizing from a main line to a branch without the use of multiple fittings.

Use the 1-1/4 inch x 1 inch copper reducing 90-degree elbow to ensure space-efficient, structurally sound directional transitions while maintaining compliance with mechanical and plumbing standards.
