Mueller Streamline 10055088 1/2 in Solder High-ear Hanger Coupling

Product Description

The MUELLER STREAMLINE 10055088 is a solder high-ear hanger coupling designed to support and join copper tubing in residential and commercial plumbing installations. Cast from brass, this 1/2 inch nominal fitting features a high-ear design that allows it to be fastened directly to a structural surface while simultaneously making a solder connection at both ends. This dual function eliminates the need for a separate pipe strap in many applications. Licensed plumbers and pipefitters install this type of fitting where copper lines need to be secured at a transition point or along a run of tubing.

This hanger coupling is suited for water supply lines, hydronic heating systems, and general plumbing rough-in work where 1/2 inch copper tubing must be anchored and coupled in a single fitting. The solder end style is compatible with standard sweat-soldering practices using lead-free solder as required by current plumbing codes. Its cast brass construction offers corrosion resistance and durability in wet or damp environments typical of mechanical rooms, crawl spaces, and wall cavities.

Key Features

• High-ear design combines pipe hanger and coupling into one fitting, reducing parts count
• Solder end style for standard sweat connections using lead-free solder
• Cast brass construction for corrosion resistance in plumbing environments
• 1/2 inch nominal size fits standard 1/2 inch copper tubing
• Suitable for both residential and commercial plumbing rough-in applications

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/2 inch nominal copper tubing systems using solder end connections.

Installation Notes

Installation should be performed by a licensed plumber following applicable local plumbing codes and ASTM or ANSI standards for soldered copper joints. Shut off and depressurize the water supply before cutting into any existing line. Clean and flux all mating surfaces before applying lead-free solder as required by the Safe Drinking Water Act for potable water systems. The ear must be fastened to a solid structural surface using an appropriate fastener before making the solder connection.
