ENGINE HOSE DESIGN GUIDE INTRODUCTION Gates Engine Hose Design Guide provides detailed information to help you select the right hoses for your engine applications. Included in this section is a molded hose design guide that helps you determine those made-to-order products for applications where standard engine products cannot be used. Use this manual to select the right engine hose for your application and economical in terms of design and availability. Contact your local Gates Account Manager for complete stocking and pricing information on any standard hose you select. He or she can also...

GENERAL DESIGN STEPS FOR HOSE Step 1: Determine the STAMP requirements Prior to designing the part, you'll need to know the Size, Temperature, Application, Material construction, and Pressure (STAMP). Step 2: Determine the design Use the STAMP information to select the best hose solution. The desired hose Material construction (see the Material Construction table) is based on Pressure and bend radius requirements. Use a straight hose if possible, as they generally are the least expensive solution. Formed hoses are used to achieve the tightest bend radii (see the Minimum Bend Radius...

ENGINE HOSE DESIGN GUIDE The best way to dimension a hose is by using X, Y, and Z coordinates of each theoretical bend intersection point (not tangency points] as in the following example. An XYZ chart is also a very good way to specify the hose. The chart follows the "right hand rule” (i.e. if X is positive to the right, and Y is positive up, then Z is positive toward you]. Another method of specifying a formed hose is by dimensions of arms (or straights], angles, and twists. This can be more difficult because each arm (or straight] length and each angle must be dimensioned in a true...

ENGINE HOSE DESIGN GUIDE Most formed hose types are only available in one wall thickness as per their specification. However, formed hose with no reinforcing layer are available in various thicknesses. The table below is a guide for estimating the vacuum performance of a formed hose based on wall thickness. These values assume a straight length of hose at a temperature of 82C (180F) degrees. Complex shapes or long I.D. expansions may reduce the vacuum resistance by half, whereas short elbow hoses can double the vacuum. If a vacuum requirement can not be met with a thicker wall, then add a...
