Mueller Streamline FTG00842 Copper Reducer 0.50C X 0.25C

Product Description

The MUELLER STREAMLINE FTG00842 is a wrot copper reducer fitting designed for straight-run copper tubing systems where a 1/2-inch line transitions down to a 1/4-inch line. It uses a female solder inlet by male solder outlet connection, making it suitable for sweated copper piping assemblies. At 0.88 inches in length, this compact fitting maintains a clean inline profile and is well-suited for tight mechanical spaces. Plumbers and HVAC techs use this style of reducer when resizing copper supply lines during new installation or retrofit work.

This fitting is used in residential and light commercial plumbing and refrigeration piping where copper tubing size reductions are required. Common applications include domestic water supply systems, HVAC refrigerant line sets where copper is specified, and hydronic systems requiring a concentric straight reducer. The solder-joint construction follows conventional sweat-fitting practice and is compatible with standard copper tubing and solder materials used in the trade.

Key Features

• Wrot copper construction for reliable, durable solder joints
• Female solder x male solder connection for inline installation
• Straight reducer profile keeps fittings compact in confined spaces
• 0.88 inch actual length for minimal footprint in the run
• Reduces from 0.50 inch to 0.25 inch in a single fitting

Compatibility

Designed as an OEM-style replacement or new-installation fitting for copper tubing systems requiring a straight 0.50C x 0.25C solder-joint reducer connection.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician following applicable local plumbing codes and ASTM or ASME solder-joint standards. Shut off and drain the water or refrigerant system and allow all components to cool before cutting and fitting. Clean tubing ends and fitting sockets thoroughly and apply appropriate flux before sweating. Avoid overheating the fitting during soldering, as excessive heat can damage the joint and distort the copper.
