Mueller Streamline W 02747 90 Elbow Long Radius C X C 1 Inch

Product Description

The MUELLER STREAMLINE w 02747 is a 1-inch, 90-degree long-radius elbow designed for copper solder-joint (sweat) connections in pressurized supply systems. It features a C x C (copper-to-copper) socket configuration, accepting standard copper tubing on both ends. The long-radius sweep reduces turbulence and pressure drop compared to a short-radius elbow, making it well suited for high-flow or pressure-sensitive lines. Licensed plumbers and pipefitters install this fitting using standard soldering or brazing procedures in compliance with applicable plumbing codes.

This fitting is intended for residential and light commercial plumbing supply and distribution systems, including domestic hot and cold water lines and hydronic heating runs. It is compatible with Type K, L, and M copper tubing in the 1-inch nominal size. The long-radius geometry is commonly selected in applications where minimizing friction loss through directional changes is a priority, such as main distribution headers and riser transitions.

Key Features

• Long-radius 90-degree sweep reduces pressure drop and flow restriction at direction changes
• C x C socket ends accept standard 1-inch copper tubing for sweat-solder or braze joining
• Wrot copper construction provides strength and resistance to corrosion in pressurized water systems
• Compatible with standard lead-free solder per NSF and applicable local codes
• Manufactured to ASME B16.22 dimensional standards for solder-joint pressure fittings

Compatibility

Designed as an OEM-style solder-joint fitting for use with 1-inch nominal copper tubing in residential and commercial pressurized plumbing supply systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local amendments. Shut off the water supply and depressurize the line before cutting and fitting. Clean all mating surfaces with emery cloth and apply flux before sweating the joint with lead-free solder or an appropriate brazing alloy. Do not apply heat to the fitting while it contains water or is under pressure.
