Mueller Streamline FTG00843 Copper Reducer Bushing

Product Description

The MUELLER STREAMLINE FTG00843 is a wrot copper reducer bushing designed for extended solder applications in residential and commercial plumbing and HVAC refrigerant piping systems. This fitting transitions from a 0.62-inch fitting (FTG) connection to a 0.38-inch copper (C) connection using a female solder inlet and male solder outlet. At 1.13 inches in length, the extended profile provides adequate engagement depth for a reliable sweat joint. Licensed plumbers and HVAC technicians rely on wrot copper fittings for their consistent wall thickness, pressure integrity, and compatibility with standard soldering practices.

This reducer bushing is suited for copper tubing installations where a step-down in pipe diameter is required without adding a full coupling or union. Common applications include domestic water supply lines, hydronic heating distribution, and refrigerant line sets where space-efficient fittings are preferred. The extended solder design allows for deeper cup engagement, which supports stronger joints in tight or vibration-prone installations.

Key Features

• Wrot copper construction for consistent wall thickness and reliable pressure performance
• Extended solder profile provides deeper cup engagement for stronger sweat joints
• Reduces from 0.62-inch FTG to 0.38-inch C in a single compact fitting
• Female solder inlet x male solder outlet connection type
• 1.13-inch length keeps the transition compact in confined spaces

Compatibility

Designed as an OEM-style replacement and standard fitment for copper tubing systems using 0.62-inch FTG and 0.38-inch C sweat connections in plumbing and HVAC applications.

Installation Notes

Installation is performed by a licensed plumber or HVAC technician using standard sweat-soldering tools including a torch, flux, and lead-free solder per local plumbing codes. Shut off and depressurize the water or refrigerant system and allow all piping to cool completely before cutting or fitting. Clean all mating surfaces with emery cloth and apply flux evenly before heating. Follow applicable IPC or local code requirements for solder alloy type, especially on potable water systems.
