Within aircraft, there are a multitude of systems that utilize hoses. Hoses can be installed for fuel lines, hydraulic systems, brakes, oil coolers, and more. Flexible aircraft hoses in particular are important in situations where parts may be subjected to vibration or the hose system needs a lot of flexibility. In this blog, we will discuss some of the important considerations and steps that should be taken into account when purchasing and installing a flexible aircraft hose.
When considering purchasing flexible hoses for your aircraft, it is important to decide whether you should purchase new, used, or surplus. When getting either used or surplus, buyers may find that they are much cheaper than new hoses. While this may make a great difference in their decision, some may be more wary of the shelf life of the hose. Shelf life, however, is often decided by the manufacturer based on their best guess, and commonly does not account for the actual life of the hose once it is installed and utilized in the aircraft. Nevertheless, ensuring that the hose is still flexible is important.
Before purchasing your hose, it is paramount that it is engineered to be capable for the application that you intend to use it for. Aircraft fuel and oil hoses need to be able to withstand the temperatures that they may be subjected to during use, and hoses for a hydraulic system need to meet needed operating pressures.
Ensuring the correct size of the hose is also always crucial for any system. Hoses are measured by their internal diameter, while a tube on the other hand may be measured from its external diameter. Sizes are also measured in 16ths of an inch, which is important to remember when finding the right fit. If you are cutting your own hose for installation, be sure that the cuts are clean so that they can be fitted properly. Also keeping extra length than what may be needed can allow for the tube to bend and flex.
