Mueller Streamline CO90STLFTGC112 Copper 90 Elbow 1-1/2 in

Product Description

The MUELLER STREAMLINE CO90STLFTGC112 is a 1-1/2 inch copper 90-degree elbow fitting configured in a Ftg x C (fitting-to-copper) end connection. It redirects copper tubing runs at a right angle and is designed for sweat-soldered installation in residential and light commercial plumbing, hydronic heating, and HVAC refrigerant or condensate piping systems. The Ftg x C configuration allows one end to accept a copper tube O.D. insertion while the other end slips over a standard copper tube, making it suitable for in-line splicing and directional changes within an existing copper pipe system. Licensed plumbers and HVAC technicians are the typical installers.

This elbow is sized for 1-1/2 inch nominal copper tubing and fits standard Type K, Type L, and Type M copper pipe of that diameter. It is commonly used in drain, waste, and vent (DWV) reroutes, domestic hot and cold water distribution, hydronic radiant or baseboard heating loops, and HVAC condensate lines where a 90-degree change of direction is required. The Ftg x C end configuration is particularly useful when connecting to the outlet of another fitting without an intervening pipe stub.

Key Features

• 90-degree turn for right-angle directional changes in copper pipe runs
• Ftg x C end configuration allows direct fitting-to-tube connections without additional couplings
• 1-1/2 inch nominal size fits standard Type K, L, and M copper tubing
• Designed for sweat-solder (brazed or soldered) installation per standard plumbing practice
• Suitable for plumbing, hydronic heating, and HVAC piping applications

Compatibility

Designed as an OEM-style sweat fitting replacement or new-installation component for 1-1/2 inch nominal copper tubing systems following ASTM B88 or equivalent copper tube standards.

Installation Notes

Installation is performed by a licensed plumber or qualified HVAC technician using standard sweat-soldering or brazing techniques. Shut off and drain the water or fluid system completely before cutting into any existing line. Clean pipe ends and fitting cups thoroughly with emery cloth and apply flux before soldering, following applicable IPC or IFGC code requirements for the jurisdiction. Do not use open-flame soldering near combustible materials without proper shielding.
