Mueller Streamline ELL00018 Copper 90 Deg Elbow 1-1/4

Product Description

The MUELLER STREAMLINE ELL00018 is a wrot copper 90-degree long radius elbow used to change flow direction in copper piping systems. With a 1-1/4 x 1-1/4 inch connection size and a C x C (copper-to-copper) sweat configuration, this fitting is designed for high-integrity soldered joints in plumbing, HVAC hydronic, and mechanical piping applications. The long radius design reduces turbulence and pressure drop through the fitting compared to standard radius elbows. Licensed plumbers and pipefitters are the primary installers of this type of fitting in both residential and light commercial systems.

This elbow is suited for use in domestic water distribution, hydronic heating and cooling loops, and general mechanical piping where a 90-degree directional change is required. The C x C sweat end connections accept standard copper tube in the 1-1/4 inch nominal size. Its wrot copper construction meets the strength and corrosion-resistance demands of potable water and closed-loop systems alike. The long radius adapter type makes it a preferred choice in applications where flow efficiency through the elbow is a factor.

Key Features

• 90-degree long radius elbow for smooth directional changes with reduced flow restriction
• Wrot copper construction for superior strength and corrosion resistance over cast fittings
• C x C sweat connections for reliable soldered joints on standard copper tube
• 1-1/4 x 1-1/4 inch connection size for common residential and light commercial piping runs
• Compact form factor at 3.6 inches height and 3.6 inches length

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 1-1/4 inch nominal copper tube systems using sweat (solder) end connections in plumbing and mechanical piping applications.

Installation Notes

Installation is performed by a licensed plumber or pipefitter following applicable IPC and local plumbing code requirements. Shut off and drain the water supply or system before cutting into any existing line. Clean and flux all mating surfaces thoroughly before soldering to ensure a leak-free joint. Do not apply heat to the fitting while it contains standing water, as steam pressure can compromise the solder joint.
