70mm Alu-Verbinder 300mm Ladeluftsystem Alu-Verbinder 70mm Aluminum Connector - Length: 300mm Beaded aluminum pipe For the connection of silicone hoses Diameter = outer diameter. Picture for reference only Wall thickness: 1,5mm Material designation: AlMgSi0,5 We manufacture our aluminum pipe connectors in house, thus being able to supply any length and shape! The aluminum connectors are perfectly suited for the connection of silicone hoses. In combination with our HD clamps the perfect symbiosis. Please keep in mind that our silicone hoses have tolerances making them fit to slightly (1-2mm) larger or smaller connectors. As a rule of thumb: inner diameter silicone hose = outer diameter aluminum connector!
