Aluminum Bent Elbow 4.000 90-Degree

The Aluminum Bent Elbow 4.000 90-Degree is an essential fitting for marine plumbing, cooling systems, and fuel lines aboard fishing boats and larger recreational vessels. Built to withstand the harsh salt-water environment and constant vibration of engine rooms, this 90-degree elbow connector redirects flow with zero compromise to pressure integrity or flow rate. Anglers and boat owners rely on this type of fitting to maintain reliable system performance during extended trips offshore or inland, where equipment failures mean lost fishing time and safety risks.

Manufactured from aerospace-grade 6061-T6 aluminum alloy, the Aluminum Bent Elbow 4.000 90-Degree delivers superior corrosion resistance and lightweight durability compared to steel or brass alternatives. The 4.000-inch nominal bore accommodates high-volume coolant circulation and fuel transfer in mid-sized to large marine engines, while the precision 90-degree bend ensures proper clearance in tight engine compartment layouts without kinks or flow restriction. Woolf Aircraft Products engineers this fitting to exact tolerances, guaranteeing thread engagement security and leak-free performance under operating pressures typical of marine propulsion and cooling circuits.

This fitting is ideal for boat builders, marine mechanics, and serious anglers performing engine maintenance or upgrades on vessels ranging from 25 to 60+ feet. Installation requires standard pipe wrench technique and compatible male or female threaded adapters; always confirm thread pitch and material compatibility with existing hose barbs or bulkhead fittings. The lightweight aluminum construction reduces overall engine weight without sacrificing strength, making it a preferred choice for performance-oriented builds and professional marine service operations.
