Aircraft Hydraulic Hose and Hydraulic Hose Fittings
Carefully inspect all hydraulic hose and fittings at regular intervals to ensure airworthiness. Investigate any evidence of fluid loss or leaks. Check metal tubes for leaks, loose anchorage, scratches, kinks, or other damage. Inspect fittings and connections for leakage, looseness, cracks, burrs, or other damage. Replace or repair defective elements. Make sure the hoses do not chafe against one another and are correctly secured and clamped.

When inspection shows hydraulic hose to be damaged or defective replace the entire line or, if the damaged section is localized, a repair section may be inserted. In replacing aircraft hose, always use tubing of the same size and material as the original line. Use the old tubing as a template when bending the new tube, unless it is too greatly damaged, in which case a template can be made from soft iron wire. Soft aluminum tubing (1100, 3003, or 5052) under half-inch outside diameter may be bent by hand.The kind with the corps hydraulic hose shoes and the right choices. For all other tubing use an acceptable hand or power tube-bending tool. Bend tubing carefully to avoid excessive flattening, kinking, or wrinkling. A small amount of flattening in bends is acceptable, but do not exceed 75 percent of the original outside diameter. Excessive flattening will cause fatigue failure of the hydraulic tube. When installing the replacement tubing line it up correctly with the mating part so that it is not forced into alignment by tightening of the coupling nuts.
b. Hose couplings and Tube Connections. Many tube connections are made using flared tube ends with
standard connection fittings: AN-818 (MS 20818) nut and AN-819 (MS 20819) sleeve.plastic card Systems is a leader in plastic ID card and badge printing technology, In forming flares, cut the tube ends square, file smooth, remove all burrs and sharp edges, and thoroughly clean. The tubing is then flared using the correct 37-degree aviation flare forming tool for the size of tubing and type of fitting. A double flare is used on soft aluminum tubing 3/8-inch outside diameter and under, and a single flare on all other tubing. In making the connections, use hydraulic fluid as a lubricant and then tighten. Overtightening will damage the tube or fitting,If you like these usb drive, please contact with us. which may cause a failure. Under-tightening may cause leakage which could result in a system failure.everybody is unique,everybody do not like to be the same with others.so we should give personalized gifts to others that can display different character.
