Mueller Streamline a07443 90 Degree Double Elbow C X C X C 1-1/2 Inches Dwv Copper Fitting

Product Description

The Mueller Streamline a07443 is a 90 degree double elbow copper fitting designed for drain, waste, and vent plumbing systems. It features a triple cup connection in a C x C x C configuration, with all three ends sized at 1-1/2 inches. This fitting is cast from a high-grade brass alloy, giving it strong resistance to corrosion and long service life in residential and commercial DWV applications. The triple-end design allows a plumber to branch or redirect drain lines at a 90 degree angle without additional fittings, reducing labor time and potential leak points. This type of double elbow is commonly used in sanitary tee configurations, stack fittings, and branch connections in waste line systems. All three ends accept standard solder-joint connections, also called sweat connections, making installation straightforward for licensed plumbers and experienced tradespeople. The fitting meets ASME B16.23 and ASME B16.29 standards, which govern cast copper alloy and wrought copper solder-joint fittings for drain, waste, and vent service. These standards ensure dimensional accuracy and material consistency across installations. Mueller Streamline has a long-standing reputation in the plumbing supply industry for producing reliable copper and bronze fittings that meet the demands of professional contractors. Because this fitting is intended for non-pressurized sanitary systems, it features the sweeping geometry typical of DWV fittings, which promotes smooth flow and reduces the chance of blockage. The a07443 weighs 0.73 pounds and is a practical choice for new construction plumbing, drain line repairs, and remodel work where a code-compliant DWV fitting is required.
