GATES INDUSTRIAL HOSE PRODUCTSSELECTION Selection OF of HOSES Hoses AND and Couplings COUPLINGS (continued) (continued)Rubber hoses are used basically to convey material. They areused for a variety of reasons, but principally for:• Flexibility; allows for changes in alignment, hookupor outlet.• Absorbing vibration.• Resistance to corrosive fluids.• Resistance to abrasion.• Providing a closed system.In applying any product, the more you know about theapplication, the better the product you choose to meet the needsof the application. This is particularly true with hose becauseof the many variables involved.Each type of hose and coupling is designed to give satisfactory,safe service life for a particular application. To obtain thisservice life, the user should:• Select the proper hose and couplings for theapplication.• Take reasonable care of the hose assembly while it isin service.• Maintain the hose assembly in good workingcondition.• Observe all applicable safety regulations.If a hose assembly was incorrectly selected to solve anapplication problem, there is very little that care andmaintenance can do to prolong its service life. It’s very simple:hoses will fail soon regardless of the care and maintenanceprovided if they are misapplied.When designing a system with rubber hose, engineeringprinciples regarding materials always apply. Take advantageof the outstanding characteristics of rubber materials listed onthe Characteristics and Resistance Information for Hose Tubeand Cover Compounds page and avoid those conditions thatshorten hose life. Some of these conditions are:• Exposure to higher-than-rated temperatures.• Exposure to severe external abuse such as kinking,pulling, excessive bending.• Exposure to corrosive fluids to which hose has littleresistance.• Subjecting hose to higher than rated workingpressure/high surge pressure.The process of selecting hoses from Industrial Hose Products#39496-000 or the following Data Pages usually is resolved inone of two ways:• Making the optimum choice from several possibleselections for an application.• Making the only choice, which satisfies all therequirements of a somewhat special application; i.e.,transfer of LP Gas.Hoses are versatile, and it’s often possible to use one type ofhose for several different applications. However, certainspecific applications are critical and/or hazardous, and the onlytype of hose used should be the one Gates recommends for thatapplication. Some of the critical or hazardous applicationsinvolving hoses are:• Steam.• Liquid Petroleum Gas (LPG).• Corrosive chemicals.• Air Drill operation.Refer to the product description pages in this catalog fordetails of hoses used in these applications.The hoses listed in this Hose Finder may be found in oneor more additional Gates catalogs or Market Specificationspublications.The Hose Finder section of this catalog is intended to give youa reference for quickly locating standard line hoses for a givenapplication. Hoses are listed by size (I.D.) and rated workingpressure. Pertinent specification information is also providedfor each hosePrecautionary NotesNot all of the sizes shown are stock items and may requireminimum order quantities. In addition, many of the largerdiameter hoses (water, material handling, etc.) are made toorder.
