9 mm Wide Band Worm Gear Clamps are an ideal choice for uniform hose sealing when connecting automotive fuel lines, as well as fuel lines for the white goods industry, sanitary facilities, machine construction, and the like. Their asymmetrical design provides even distribution of force and safe assembly. Hoses are protected by the curved band edges, and by the interior of the band, which is either smooth or stamped. They have a wide clamping range, and are available in several different materials and accessory options to suit your application needs.
