Review UNIVERSAL MARINE Westerbeke Exhaust Flange

Introducing the Westerbeke Marine Exhaust Flange A11B3 (Part Number: 260458), a crucial component designed for efficient and effective exhaust gas expulsion in marine applications. This flange, manufactured by the renowned Westerbeke Engine Company, is engineered to meet the specific demands of marine environments.

The Westerbeke Exhaust Flange A11B3 is a high-performance, corrosion-resistant component, constructed primarily from 316L stainless steel.

The flange features a size of 4.5 inches (114.3mm) in diameter and a thickness of 0.312 inches (8mm). Its angled design facilitates proper exhaust gas flow and minimizes the risk of water intrusion, which is common in marine applications.

This exhaust flange comes with a gasket, which is essential for creating a tight seal between the flange and the engine or exhaust system. The gasket is made from an elastomeric material, allowing it to expand and contract with temperature changes and reduce the risk of leaks.

In summary, the Westerbeke Marine Exhaust Flange A11B3 (Part Number: 260458) is a high-quality, durable, and reliable component designed for marine exhaust applications. Its corrosion-resistant, stainless steel construction ensures longevity, while its angled design facilitates proper exhaust gas flow and minimizes the risk of water intrusion. The included gasket ensures a tight seal, reducing the risk of leaks and maximizing system performance.
