When you purchase a Rubberworx Premade Dock Hose from our ecommerce site, it comes fully assembled with all necessary components including couplings on both ends of the hose. Each coupling is secured using band clamps that provide reliable attachment points between the hose and any other equipment it's connected to within your industrial setting. Our premade hoses are also pre-tested before they leave our facility so you can trust that they'll perform effectively upon arrival.
