The first practical hose was invented in the 17th century in Holland. The hose was made of leather that was 50-foot of length. It had brass screws attached at the ends enabling the sections to be connected thus allowing a proper flow of water at higher pressure. The hoses were made in such a way that they could withstand more pressure of up to 200 square foot.
- Pressure rating
- Straight hose
- Chemical compatibility
Hose connectors fittings are used in various applications that include scuba diving in underwater diving, to aid in supplying air from the surface or diving pumps to the diver under water. Air hoses can also be used on locomotives and railroad cars for their breaks. Tractors and semi-trailers that use that use air break also have air hoses in between them.
The air hoses can be made from a combination of various materials or a single material. The materials used mostly include nylon, polyurethane, polyethylene, polyvinylchloride, together with synthetic or natural rubber.
Types of air hoses
Air hoses that are in use include the following types:
- Air hose employed in supplying air to the diver on the surface.
- Low-pressure air hoses. These are used to connect demand valve and also in the inflation of dry suits and buoyancy compensators. The pressure employed in this air hose goes up to 290 psi.
- High-pressure gauges, these are utilized in connecting to a pressure gauge. The pressure applied in this goes up to 4,400psi.
