Mueller Streamline W-6051 Copper Return Bend 5/8 in

Product Description

The MUELLER STREAMLINE W-6051 is a full-size copper return bend fitting designed to reverse flow direction in copper tubing systems. With a 5/8 inch tube size and a center-to-center dimension of 1 9/16 inches, this fitting provides a clean, pressure-tight U-turn connection in refrigeration, HVAC, and plumbing applications. It is manufactured from copper for reliable corrosion resistance and long service life. Plumbers, HVAC technicians, and refrigeration mechanics install this type of fitting when routing tubing through tight spaces or constructing coil assemblies.

This return bend is suited for residential and light commercial applications where copper tubing must reverse direction within a confined run. It is commonly used in evaporator and condenser coil assemblies, refrigerant line sets, and hydronic tubing systems. The full-size (FS) designation indicates the fitting matches the full nominal tube outer diameter, allowing standard sweat soldering without reducers or adapters. It is sold individually and is compatible with standard 5/8 inch copper tubing used across HVAC and plumbing trades.

Key Features

• Full-size 5/8 inch copper construction for direct sweat connection to matching tube stock
• 1 9/16 inch center-to-center spacing for compact routing in coil and tubing assemblies
• Copper material provides inherent corrosion resistance and compatibility with refrigerant and water systems
• U-bend geometry reverses flow direction without additional fittings or offsets
• Sold as a single unit for precise quantity ordering on service and fabrication jobs

Compatibility

Designed as an OEM-style sweat fitting for use with standard 5/8 inch copper tubing in refrigeration, HVAC coil, and plumbing applications.

Installation Notes

Installation of copper return bends is typically performed by licensed HVAC technicians, refrigeration mechanics, or journeyman plumbers. Shut off and recover any refrigerant charge or depressurize water lines fully before cutting into an existing system. Clean and flux all mating surfaces before soldering, and use the appropriate filler alloy for the application per applicable mechanical codes. Avoid overheating the fitting during torch work, as excessive heat can weaken the joint or distort the bend geometry.
