- Description
Air system hoses for Mi-8 and Mi-17 helicopters are used in pneumatic, air supply, control-air and ventilation circuits where stable air pressure and reliable sealing are required. These are not general-purpose rubber hoses; in aviation maintenance they are selected by aircraft part number, hose type, installation point, pressure class, fitting arrangement and the specific onboard system where the line is installed.
On Mi-8 / Mi-17 family helicopters, pneumatic hoses may be used in air distribution lines, ventilation ducts, control-air circuits, pressure indication lines, brake-related pneumatic sections and auxiliary air systems. Some assemblies work close to structural elements, landing gear areas, instrument pressure lines or equipment compartments where vibration, temperature changes and mechanical movement can affect service life. Because of this, even visually similar hose assemblies may not be interchangeable.
This category includes OST-standard pneumatic hoses, U-series flexible hoses, 8A-series hose types and complete air system hose assemblies used on Mi-8, Mi-17 and related Mi-171 helicopter versions. Depending on the application, the hose may be supplied as a simple flexible line, a reinforced pneumatic hose, a pressure line with fittings or a ready-to-install assembly manufactured according to the required part number, drawing, sample or technical specification.
All air system hoses in this category are supplied only in factory new condition. Used, repaired, overhauled or serviceable hoses are not offered. For pneumatic and ventilation lines, material age, airtightness, reinforcement condition, fitting quality and compatibility with the operating environment are important for safe installation and further maintenance planning.
For MRO companies, repair plants and fleet operators working with Mi-8 / Mi-17 helicopters, replacement of air system hoses is often required during scheduled maintenance, overhaul, troubleshooting of pneumatic circuits, cockpit or equipment ventilation work and long-term fleet support programs. In many cases, the correct selection depends on the exact hose routing and the aircraft modification, not only on the general system name.
Aviamisto supplies Mi-8 and Mi-17 air system hoses, pneumatic hose assemblies and related helicopter spare parts for aviation operators, MRO organizations and aircraft parts suppliers. Some standard positions may be available from UAE or EU stock locations, while less common hose assemblies are produced or sourced upon request after confirmation of the part number, configuration and required documentation. Technical passports, certificates of conformity, batch traceability or origin documents may be provided for selected items when available.
