How It's Made – Hose Assemblies
A hose assembly consists of a hose, a fitting, and a clamp or collar to attach the parts together. Although they are separate components, they must be joined correctly and precisely in order to perform well as a unit. Mismatched sizes or clamps and collars that are incorrectly installed can lead to leaks, hose failures, lost time and added costs.
Hose assemblies can be simple to construct, depending on the materials involved. If an assembly made from a flexible tubing material is needed – polyurethane, for example – the process is as easy as selecting the proper-size and style of barbed fitting, inserting it into the end of the tubing, and securing the two together with a properly-tightened hose clamp. This type of assembly can be done with simple tools like a screwdriver or pliers.
When multi-layer hoses are involved, the process is quite different. Collars must be crimped or swaged onto the hose by machine in order to attach a fitting. The first step is to cut the hose to the desired length. A collar and fitting are then placed on the hose, and the juncture is inserted into a crimping or swaging machine. These devices uniformly apply pressure around the circumference of the collar, permanently sealing it and the fitting to the hose. The use of modern crimping machines makes the crimp method of attaching collars to a hose the recommended technique for hose assembly fabrication.
Depending on a customer's needs, other steps in the hose assembly process can involve interior and exterior cleaning, identification such as wired-on tags, pressure testing for leaks, and special packaging to ensure cleanliness.
