Mueller Streamline ELL00921 90 Degree Copper Street Elbow

Product Description

The MUELLER STREAMLINE ELL00921 is a 90-degree wrot copper street elbow designed for close-rough plumbing applications. It features a short-radius, street-style configuration with a fitting-by-sweat (FTG x C) connection type in a 1/4 x 1/4 inch size. At 0.01 pounds, this compact fitting measures 0.97 inches in length and 0.88 inches in width, making it suited for tight-clearance installations where standard-radius fittings will not fit. Plumbers and pipefitters use this elbow to make directional changes in small-diameter copper tubing runs without adding unnecessary length to the assembly.

This elbow is commonly used in residential and light commercial plumbing systems wherever 1/4 inch copper tubing requires a 90-degree turn in a confined space. The FTG x C connection allows one end to slip directly into another fitting socket, eliminating the need for an additional coupling. Typical install scenarios include refrigeration lines, ice maker supply lines, and small-diameter domestic water lines. This part corresponds to the WE-503 pattern designation used across the Streamline product line.

Key Features

• 90-degree short-radius street elbow for directional changes in tight spaces
• Wrot copper construction for durability and reliable solder joints
• FTG x C connection allows direct in-line fitting insertion without an extra coupling
• 1/4 x 1/4 inch size suits small-diameter copper tubing applications
• Close-rough profile minimizes installed length in confined areas

Compatibility

Designed as an OEM-style replacement and standard-use fitting for 1/4 inch copper tubing systems using sweat-solder connections per the WE-503 close-rough street elbow pattern.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and depressurize the line before cutting or soldering. Clean all mating surfaces with emery cloth and apply flux before sweating the joint. Avoid overheating the fitting during soldering, as excessive heat can damage the wrot copper and result in a failed joint.
