Mueller Streamline a11555nl 90 Degree Elbow with Drain Cup X Cup 1/2 Inch Lead-free Cast Brass

Product Description

The Mueller Streamline A11555NL is a 90 degree elbow with drain fitting designed for use in above-ground potable water supply and pressurized plumbing systems. This fitting is manufactured from lead-free cast brass alloy, making it a code-compliant choice for drinking water applications where lead-free materials are required by code. The fitting uses a cup by cup (C x C) solder-joint connection on both ends, each sized at 1/2 inch, allowing plumbers and pipefitters to sweat-solder the fitting directly onto standard 1/2 inch copper tubing. The integrated drain port is a practical feature that allows technicians to drain a section of pipe without removing the fitting or cutting into the line, saving time during maintenance, winterization, and system repairs. Mueller Streamline has been a trusted name in copper and brass solder-joint fittings for over 80 years, and the A11555NL reflects that legacy of precision manufacturing and consistent quality. This fitting is produced to meet multiple ASME standards including B16.15, B16.18, B16.22, B16.24, B16.50, and B1.20.1, ensuring it meets the dimensional and performance requirements that engineers and inspectors expect on commercial and residential plumbing projects. The lead-free cast brass construction provides strong corrosion resistance and durability in pressurized water systems. At approximately 0.10 pounds, this compact fitting is lightweight and easy to handle during installation. Whether you are a plumber, pipefitter, or mechanical contractor working on new construction or a service call, this elbow with drain delivers reliable performance in copper plumbing systems.

• Lead-free cast brass alloy construction meets drinking water compliance requirements
