The oval flange, code 170901, is a precision-engineered connection component developed for the MAN L21/31 engine to establish strong and pressure-resistant joints between piping systems, hoses, and mechanical interfaces. Its oval geometry allows efficient installation in confined engine spaces while ensuring balanced load distribution and dependable sealing performance. Manufactured from robust and corrosion-resistant materials, the flange is designed to withstand vibration, thermal expansion, and demanding marine and industrial operating conditions. By providing stable and leak-tight connections, the oval flange supports safe fluid transfer, minimizes operational risks, and contributes to the overall reliability and long-term durability of the engine systems.
