Selection, Installation & Maintenance 5.14 Hose Fittings � Selection of the proper hose fittings for the hose and application is essential for proper operation and safe use of hose and related assembly equipment. Hose fittings are qualified with the hose. Therefore, select only hose fittings compatible with the hose for the applications. Improper selection of hose fittings or related assembly equipment for the application can result in injury or damage from leaks, or from hose assemblies blowing apart (see 4.2, 6.2, 6.3 and 6.4). Incorrect Correct 5.15 Vibration � Vibration can reduce hose service life. If required, conduct tests to evaluate the frequency and amplitude of system vibration. Clamps or other means may be used to reduce the effects of vibration. Consider the FIGURE 2 -- ELBOWS AND ADAPTERS vibration requirements when selecting hose and predicting service life. 5.23 Lengths � Unnecessarily long hose can increase pres- sure drop and affect system performance. When pressurized, 5.16 Hose Cover Protection � Protect the hose cover from hose that is too short may pull loose from its fittings, or stress abrasion, erosion, snagging and cutting. Special abrasion- the fitting connections, causing premature metallic or seal resistant hoses and hose guards are available for additional failures. When establishing hose length, refer to Figures 3, 4, protection. Route hose to reduce abrasion from hose rubbing and 5; and use the following practices: other hose or objects that may abrade it. 5.23.1 Motion Absorption � Provide adequate hose length 5.17 External Physical Abuse � Route hose to avoid: to distribute movement and prevent bends smaller than the A.

Twisting 5.18 Swivel-Type Adapters � Swivel-type fittings or adapt- ers do not transfer torque to hose while being tightened. Use these as needed to prevent twisting during installation.

These connectors reduce the torque transmitted to tolerances. the hose. 5.20 Slings and Clamps � Use slings and clamps to support heavy or long hose and to keep it away from moving parts. Use clamps that prevent hose movement that will cause abrasion. Correct Incorrect 5.21 Minimum Bend Radius � The minimum bend radius is defined in SAE J343 and is specified in other SAE standards and hose manufacturer's product literature. Routing at less than minimum bend radius may reduce hose life.
