Mueller Streamline a11206nl Union C X C 1-1/2 Inches Lead-free Cast Brass

Product Description

The Mueller Streamline A11206NL is a 1-1/2 inch copper union fitting designed for use in above-ground potable water supply and pressurized plumbing systems. It features a C x C (cup by cup) end configuration, meaning both ends accept standard copper tubing joined by sweat soldering. This fitting is manufactured from lead-free cast brass alloy, making it a compliant choice for drinking water applications where low-lead materials are required by code. Plumbers and pipefitters rely on this style of union to create a breakable connection in a copper line, allowing sections of pipe to be disconnected and reconnected without cutting. This is especially useful for maintenance access points, equipment connections, and service shutoffs. The A11206NL weighs 1.04 pounds and is built to the dimensional and performance standards that copper solder-joint fittings are known for across commercial and residential plumbing. Mueller Streamline has manufactured copper and brass solder-joint fittings for over 80 years and is recognized as a leading supplier in the trade. Their fittings are specified by engineers and used by plumbing contractors worldwide because of their consistent quality and long service life. This union meets multiple ASME standards including B16.18 and B16.22, ensuring it conforms to accepted industry dimensions and pressure ratings for copper fittings. The cup ends are sized at 1-1/2 inches on both sides, compatible with standard Type K, L, and M copper tubing. Whether used in new construction or a retrofit application, this fitting delivers a reliable, leak-free solder joint when properly installed.
