onto the hose), clamp fittings (where two blocks are tightened onto the sides of the hose, often found on garden hoses), crimp banding (similar to worm gear banding but a crimp is used instead of a screw/thread), and a multitude of others. However, these devices are not typically referred to as hose clamps. Uses and applications Hose clamps are typically limited to moderate pressures, such as those found in automotive and home applications. At high pressures, especially with large hose sizes, the clamp would have to be unwieldy to be able to withstand the forces expanding it without allowing the hose to slide off the barb or a leak to form. For these high pressure applications, compression fittings, thick crimp fittings, or other designs are normally used. Hose clamps are frequently used for things other than their intended use, and are often used as a more permanent version of duct tape wherever a tightening band around something would be useful. The screw band type in particular is very strong, and is used for non-plumbing purposes far more than the other types. These clamps can be found doing everything from mounting signs to holding together emergency (or otherwise) home repairs. Another handy attribute: worm-drive hose clamps can be daisy-chained or "siamesed" to make a long clamp, if you have several, shorter than the job requires. Some things seen assembled with hose clamps include the tail boom on a GMP Cricket model helicopter, a homemade gas scooter, makeshift pipe hangers, mounts for rooftop TV and shortwave antennas, and virtually every imaginable automobile body component. Hose clamps are commonly used in the agriculture industry as well. They are used on Anhydrous Ammonia hoses and are made from a combination of steel and iron. Anhydrous ammonia hose clamps are often cadmium plated to prevent rust and corrosion. Sealing and mechanical strength One of the fundamental goals of most hose clamps is to ensure a tight seal between the hose and the barb, preventing the working fluid from escaping. To this goal, they are designed to provide even pressure on all sides, with no gaps. An example of this would be wire clamps. An obvious design would seem to be simply having a wire around the hose, one end attached to a nut, and the other end to the screw, and when tightened, pulling the ends of the wire towards each other. However, this will
