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