Mild Steel Bent Elbow 4.500 90-Degree

The WOOLF AIRCRAFT PRODUCTS Mild Steel Bent Elbow 4.500 90-Degree is a precision-engineered exhaust bend designed for marine engine systems and custom exhaust applications. This 4.5-inch diameter bend features a 4.5-inch radius with a 90-degree angle, delivering smooth flow characteristics essential for efficient exhaust routing on boats, inboard engines, and industrial marine equipment. Constructed from mild steel in natural finish, it provides reliable performance in high-temperature exhaust environments where durability and proper gas flow management are critical.

The 16-gauge steel construction balances structural integrity with weight efficiency—important considerations for marine applications where corrosion resistance and longevity depend on proper material selection and maintenance. The 4.5-inch radius bend is engineered to minimize turbulence and backpressure in the exhaust system, which directly impacts engine performance and fuel efficiency. The bend's 90-degree angle allows for flexible routing around engine compartments and through hull spaces, accommodating tight installations common in retrofit work and custom marine builds. Each unit weighs 5.5 pounds and measures 15.5 x 4.55 x 16.1 inches, fitting standard marine exhaust systems that use 4.5-inch diameter piping.

This exhaust bend serves weekend boaters performing engine maintenance and serious marine mechanics building or restoring marine propulsion systems. It's ideal for inboard gasoline or diesel engines requiring custom exhaust re-routing, replacement of corroded bends, or installation in new engine installations. The natural steel finish requires proper sealing or coating in saltwater environments to prevent rust; freshwater and protected-water applications may see extended service life with standard maintenance. WOOLF AIRCRAFT PRODUCTS is recognized for precision metal fabrication in aviation and marine sectors, bringing that manufacturing standard to aftermarket exhaust components.

When sourcing exhaust components for marine engines, the radius and angle of the bend directly affect gas velocity and scavenging efficiency. A properly matched radius prevents excessive turbulence while allowing adequate clearance in confined engine spaces. This 4.5-inch elbow is compatible with standard marine piping systems and integrates with exhaust manifolds, risers, and muffler assemblies common to recreational and commercial marine powerplants.
