Aluminum Bent Elbow 4.000 45-Degree

The WOOLF AIRCRAFT PRODUCTS Aluminum Bent Elbow 4.000 45-Degree is a precision-engineered aluminum tubing bend designed for marine plumbing, cooling systems, and fuel line applications where reliability and corrosion resistance are critical. Built from 6061-T6 aluminum alloy with a 0.065-inch wall thickness, this 45-degree elbow accommodates 4-inch diameter tubing and features a 4-inch bend radius, making it suitable for both compact installations and systems requiring smooth flow characteristics without turbulence.

The 6061 aluminum alloy selected for this component offers excellent seawater and salt-spray corrosion resistance—essential for offshore and coastal vessels where steel alternatives would degrade rapidly. The natural finish allows for easy welding, brazing, or mechanical fastening, depending on your system configuration. At 1.15 pounds per elbow, it minimizes added weight while maintaining structural integrity under typical marine system pressures. The 4-inch bend radius reduces flow loss compared to sharper elbows, improving system efficiency in high-capacity cooling and fuel transfer applications.

This component is commonly specified for custom cooling loops, through-hull water systems, and fuel distribution networks on fishing vessels, recreational cruisers, and commercial marine equipment. Whether you're rebuilding a vintage engine cooling system, upgrading fuel lines for improved flow, or fabricating a custom hydraulic or water circulation setup, this aluminum elbow delivers the durability and performance expected in demanding saltwater environments. The 45-degree angle provides versatility in tight engine compartments and below-deck installations where 90-degree bends would create installation challenges.
