It is commonly used on commercial truck or trailer tanks for engine oil, fuel, or hydraulic systems to provide a secure, leak-resistant connection for a drain valve, sight glass, or suction line. The flange is made from corrosion-resistant aluminum and is typically welded or bolted to the bottom of a sump. Replacement is needed when the flange becomes damaged, corroded, or develops leaks at the gasket.
