304 Stainless Bent Elbow 4.500 180-Degree

The WOOLF AIRCRAFT PRODUCTS 304 Stainless Bent Elbow 4.500 180-Degree is a marine-grade exhaust bend designed for inboard and outboard engine systems requiring corrosion-resistant, precision-engineered exhaust routing. Built from 304 stainless steel—the industry standard for saltwater applications—this 180-degree elbow delivers the durability and reliability that serious boaters depend on when operating in harsh marine environments.

This exhaust bend features a 4.5-inch diameter with a 6.75-inch centerline radius and 16-gauge wall thickness, engineered to handle continuous high-temperature exhaust flow while resisting salt-air corrosion. The 180-degree configuration allows for tight, efficient bends in confined engine compartments typical of center-console fishing boats, cabin cruisers, and commercial marine vessels. The smooth interior radius minimizes backpressure and turbulence, supporting optimal engine scavenging and fuel efficiency. At 8.05 pounds, the component integrates seamlessly into existing exhaust systems without adding excessive weight topside.

Anglers and boat owners maintaining gasoline or diesel inboards recognize that exhaust system integrity directly impacts engine longevity and resale value. This stainless elbow replaces corroded or damaged bends that weaken under repeated heating cycles and saltwater exposure. Whether you're rebuilding an aging cooling system, upgrading exhaust plumbing, or repairing battle-tested equipment, this WOOLF component delivers verified marine-grade construction backed by decades of OEM and aftermarket use in the boating industry.

The natural (uncoated) 304 stainless finish resists rust without additional painting or powder coating, simplifying maintenance in salt spray conditions. For weekend fishermen and offshore operators alike, this exhaust bend represents a straightforward, proven solution for keeping marine propulsion systems running clean and efficient season after season.
