This flexible hose clamp set includes three clamps: 155mm, 185mm and 255mm. Each one is operated using a simple one-handed locking mechanism. All are made from a lightweight but strong composite material, carefully crafted from nylon and fibreglass. They are non-conductive and have rounded jaw edges to prevent damage to the hose. The set includes the following maximum jaw capacities: 18, 34, 67mm. Each clamp is a high visibility colour to help ensure the tool gets noticed and is not left attached to the vehicle. The set is suitable for use on most flexible rubber hoses including coolant, brakes, fuel, and vacuum hoses.
