1-1/2 inch x 1 inch Copper Long Radius Reducing 90° Elbow – For Directional Transitions in Potable Water and Hydronic Systems

The 1-1/2 inch x 1 inch Copper Long Radius Reducing 90 Degree Elbow is a wrot copper fitting designed for use in systems requiring a directional change between dissimilar pipe sizes. The long radius configuration provides a gradual change in flow direction, minimizing pressure loss and turbulence, making it ideal for potable water, chilled water, and low-pressure steam applications.

This fitting complies with the dimensional and performance standards of ASME B16.22 and is manufactured from lead-free copper (Alloy C12200) per ASTM B75, meeting the requirements of the Safe Drinking Water Act (SDWA) and NSF/ANSI 61 & 372 for potable systems. The elbow features solder (cup) ends on both outlets, facilitating reliable capillary joining with copper tubing using standard brazing or soldering methods.

Key Performance Features

• ✅ Material: Wrought copper (C12200) – lead-free and corrosion-resistant
• ✅ Configuration: 90° long radius reducing elbow for improved flow characteristics
• ✅ Connection Type: Female solder cup x solder cup
• ✅ Nominal Sizes: 1-1/2 inch x 1 inch (inside diameter)
• ✅ Standard Compliance: ASME B16.22, ASTM B75, NSF/ANSI 61 & 372

Applications

Used in commercial and residential potable water systems, closed-loop hydronic heating, HVAC piping, and other mechanical applications requiring a smooth, low-restriction change in direction and pipe diameter. Long radius elbows are especially beneficial where flow efficiency and reduced noise/vibration are important, such as in recirculating systems and main distribution lines.

Installation Guidelines

Clean and ream tubing ends before inserting into the fitting socket. Apply flux and use lead-free solder for potable systems, following ASTM B828 procedures for soldered copper joints. Ensure compliance with local code requirements for joint spacing, pipe support, and brazing if higher pressure or temperature conditions exist. Avoid excessive heat to prevent annealing of the fitting during soldering.
