In order to obtain the best service from any particular hose application, two important conditions must be fulfilled: You must select the correct hose for the job. And, you must make sure, that after having obtained the right hose, it is fitted correctly and used in a proper manner.
When considering a particular hose application, the following basic factors should be considered:
-

Inside diameter (ID)
-
Outside diameter (OD)
-
Materials being conveyed (e.g., air, water, acids, oils, steam, etc.)
-
Precise composition of substance (important in the case of oils, solvents, spraying media, foods, beverages, petroleum products, gases, etc.)
-
Concentration (in the case of chemicals)
-
Maximum temperature of substance
-
Maximum pressure (including any possible surge or back pressure)
-
Degree of vacuum (in the case of suction hose)
-
External conditions. The scope of this factor is possibly the widest of all and covers such things as: Abrasion; Climactic conditions; Direct heat; Radiated heat; Contamination from oil, grease, solvents, acids, etc.; End loads; Flexings — degree and cycle; Crushing conditions; Kinking conditions

Air, steam, and water hoses are the three types of hose most used in industrial plants.

Steam Hose
Generally, steam service is usually the most severe in the average plant. In selecting a hose for a steam at elevated temperatures, consider that steam severely affects rubber hose of all types. It is therefore important that temperature be considered in the choice of a steam hose.
High steam temperature and pressure can cause deterioration in certain reinforcing members used in hose. A relatively small increase in temperature can greatly affect hose performance. The steam pressure is important in that it determines the minimum temperature condition under which the hose will be used. If the steam is saturated, its temperature is directly related to its pressure.
However, if steam is superheated, the degree of superheating must be known to determine the actual temperature which the hose must withstand. The flex factor takes into consideration the magnitude of the flexing and its time cycle. The degree of flexing is an important factor in the ultimate life of the hose. A flexing that is rapid and continuous, even though of small magnitude, would be considered as severe as flexing that is large in magnitude but with an extremely long time cycle.

Air Hose
Many fine types of air hose, equipped with tough, abrasion resisting covers and are offered with tube stocks which will successfully resist oil mist, if present.
Where tools are lubricated through hose, only the very best quality air hose with highest grade oil-resisting tube should be used. The recommended working pressure should be sufficient to withstand the maximum pressures encountered.

Water Hose
In the selection of the correct water hose for any service, the same principles apply as for air and steam hose.
Suction Hose
Most Goodyear Engineered Products vacuum or suction hose are designed to withstand full vacuum. However, in some of the lighter styles, less than full vacuum is recommended. To assist your efforts to collect the data necessary to make a proper hose recommendation, use this form from the Hose catalog or use Goodyear EP HoseSelect™ online.
