Mueller Streamline a11556nl 90 Degree Elbow with Drain Cup X Cup 3/4 Inches Lead-free Forged Brass

Product Description

The Mueller Streamline A11556NL is a 90 degree elbow fitting with an integrated drain, designed for 3/4 inch copper solder-joint connections. It features a Cup x Cup (C x C) end configuration, meaning both ends accept standard copper tubing for sweat soldering. This fitting is manufactured from lead-free forged brass alloy, making it fully compliant with current potable water regulations and safe for use in above-ground drinking water supply systems. Plumbers, pipefitters, and mechanical contractors rely on Mueller Streamline fittings for their precision tolerances and consistent quality across every job, whether residential, commercial, or light industrial. The 90 degree turn with a built-in drain port adds practical utility to standard directional changes in a pipe run. The drain port allows technicians to easily drain a section of pipe for maintenance, repair, or winterization without cutting into the line. This eliminates the need for a separate drain valve in many applications, saving both time and materials. Mueller Streamline has been a leading name in copper solder-joint fittings for over 80 years. Their fittings are engineered to meet the most demanding ASME standards, including B16.15, B16.18, B16.22, B16.24, B16.50, and B1.20.1. These standards govern dimensions, pressure ratings, and materials for copper and bronze pressure fittings. The lead-free forged brass construction delivers excellent corrosion resistance and long service life in pressurized water systems. At 0.20 pounds, this fitting is compact and easy to handle during installation. HVAC technicians and plumbers who work on hydronic heating systems, domestic water supply lines, or chilled water piping will find this fitting a dependable choice for making clean, code-compliant 90 degree directional changes with integrated drain capability.

• Lead-free forged brass alloy construction meets potable water safety requirements
• Integrated drain port allows easy system draining without additional valves
• Cup x Cup solder-joint ends sized at 3/4 inches for standard copper tubing connections
