Fuel hose Aeroquip®

Eaton’s 601/701 series of flexible hose assemblies are designed to operate at nominal pressure below 1,500 psi (depending on size) for fuel, hydraulic, coolant and other aircraft fluids. Hoses provide motion and flexibility for systems with expected movement/vibration and allow for easier service and connect/disconnect. Base hose made from synthetic rubber supports fluid compatibility and weight reduction. Eaton’s Aeroquip part number 900780 Internal Support Coil is used to help prevent damage to hoses which are subject to mishandling, vacuum application, or tight installation. Part number 900800A Internal Sleeve is to be used in conjunction with the Internal Support Coil. It acts as an anchor point for the coil and prevents fluids of high viscosity or extreme flow rates from forcing the Internal Support Coil out through the end fittings. The Internal Support Coil is a flat, helically wound, stainless steel reinforcing coil of 302 type- AMS-5516. Installation Instructions Step 1. Determine the proper size and style of hose and fittings for the application. Step 2. Cut the hose to the proper length (“J” factor). Step 3. Select the proper size internal support coil and internal sleeve (2 required) from Table 1. Step 4. Determine the correct length of coil to be cut using the applicable formula from Table 1. Step 5. Cut by any convenient method and remove all sharp edges and corners. Step 6. Both ends of the internal support coil should then be bent into tabs as shown below. Step 7. To install the internal support coil in the hose, use a rod or a piece of tubing slightly longer than the cut length of the hose.
