Southwark Metal 901826 90 Degree Adjustable Elbow 18 Inches 26 Gauge

Product Description

The Southwark Metal 901826 is an 18-inch, 90-degree adjustable elbow fabricated from 26-gauge hot-dipped galvanized steel meeting ASTM A653 CS Type B standards. This fitting is designed for use in low-pressure sheet metal ductwork systems where directional changes are required. HVAC installers and sheet metal contractors rely on adjustable elbows like this one to make precise 90-degree turns in supply and return air distribution systems. The adjustable design allows the installer to fine-tune the angle during installation, reducing the need for custom fabrication on the job site and speeding up the overall duct installation process. The 26-gauge galvanized steel construction provides a solid balance of rigidity and workability, making it easy to cut, fasten, and seal. The hot-dipped galvanized finish protects the steel from corrosion in both residential and commercial HVAC applications, including attics, crawl spaces, and mechanical rooms where moisture can be a factor. This elbow features a crimped male connection on one end and a straight female connection on the other, allowing it to connect directly to round ductwork without additional adapters in most configurations. The 1-inch crimp length is sized to accept standard duct connections, and the 1/2-inch overlap is designed for riveting using 1/8-inch rivets, ensuring a secure, airtight joint when properly fastened and sealed. At 18 inches in diameter, this fitting is suited for larger trunk lines and main distribution runs in commercial or large residential HVAC systems. Southwark Metal is a well-established manufacturer of HVAC sheet metal products, and this elbow is part of a broader line that includes sizes from 3 inches through 24 inches, with select sizes also available in aluminum and Type 304 stainless steel for specialized applications.
