How to select the proper hose for your application

April 9, 2013

Use the information on our site to help determine the proper hose for your application. This will help you obtain the data necessary to make a proper hose selection. A simple way is to remember the stamped theory. "S.T.A.M.P.E.D."

S.T.A.M.P.E.D.

• S stands for SIZE; I.D., O.D. and length
• T stands for TEMPERATURE of the material conveyed and environmental both internal and external
• A stands for the APPLICATION, the conditions of use
• M stands for the MATERIAL being conveyed internally type, and concentration
• P stands for the PRESSURE the hose will need to meet or exceed for its application
• E stands for ENDS; style, type, orientation, attachment methods, etc.
• D stands for DELIVERY; testing, quality, packaging, and delivery requirements

General Selection Information

In order to obtain the best service from any particular hose application, two important conditions must be fulfilled:

1. To select the proper hose for the job.
2. To make sure, that after having obtained the proper hose, it is fitted correctly and used in a proper manner.

When considering a particular hose application, the following basic factors should be considered:

1. Inside diameter
2. Outside diameter
3. Materials being conveyed internally (e.g. air, water, acids, oils, steam, etc.)
4. Precise composition of substance (important in the case of oils, solvents, spraying media, foods, beverages, petroleum products, gases, etc.)
5. Concentration (in the case of chemicals).??
6. Maximum temperature of substance.
7. Maximum pressure (including any possible surge or back pressure).
8. Degree of vacuum (in the case of suction hose).??
9. 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
   • Flexing - degree and cycle
   • Crushing conditions
   • Kinking conditions
   • Degree of bending
10. Details of couplings (particularly in specialized applications).
