Mueller Streamline ELL00903 Wrot Copper 45 Deg Street Elbow

Product Description

The MUELLER STREAMLINE ELL00903 is a wrot copper street elbow designed for sweat-solder copper piping systems. It provides a 45-degree change of direction in tight spaces where a standard elbow will not fit, thanks to its street (FTG x C) end configuration. One end accepts a copper fitting socket, while the other accepts copper tube directly, eliminating the need for an extra coupling in confined runs. Measuring 1.55 inches in length and 0.43 inches in width, this compact fitting weighs just 0.01 pounds. It is intended for use by licensed plumbers and pipefitters working on residential and light commercial copper water, refrigeration, or HVAC piping installations.

This fitting is suited for 1/4-inch copper tube applications, including refrigeration line sets, ACR piping, and potable water distribution where a 45-degree offset is required. The street end slides directly into an adjacent copper fitting cup, making it especially useful in back-to-back fitting configurations and retrofit repairs where working clearance is limited. Plumbing and HVAC contractors commonly use this size in small-bore refrigerant and water lines.

Key Features

• Wrot copper construction provides high strength and reliable solderability for pressure piping systems
• Street (FTG x C) end configuration allows direct fitting-to-fitting connection without an additional coupling
• 45-degree angle delivers gradual directional change, reducing flow turbulence compared to 90-degree fittings
• 1/4 x 1/4 inch connection size covers small-bore refrigeration and water line applications
• Compact dimensions at 1.55 inches length and 0.43 inches width suit tight installation spaces

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/4-inch wrot copper sweat-solder piping systems in plumbing and HVAC applications.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician in accordance with applicable local plumbing codes and ASTM B88 or B280 copper tube standards. Shut off and depressurize the line and allow it to cool completely before cutting or soldering. Clean both the fitting socket and tube end with emery cloth or a fitting brush, apply lead-free flux, and heat evenly before introducing solder. Do not overheat the fitting, as excessive heat can cause oxidation that prevents a sound solder joint.
