Three Basic Elements of a Hose
Its purpose is to handle specific fluids or solids. It is the innermost rubber or plastic component of the hose that must be resistant to the material being conveyed because it is in contact with the material. A variety of compounds can be used depending on the application.
Its purpose is to withstand a specific amount of working pressure measured in pounds per square inch (psi) or Pascal (Pa) or vacuum (In Hg, inches of mercury). The reinforcement may consist of multiple layers of fabric, yarn or wire placed on top of the tube and referred to as “plies.”
Its primary purpose is to protect the tube and reinforcement from external factors such as ozone, weather, abrasion and heat. A variety of compounds can be used depending on the application
