- Description
Pneumatic system hoses for Mi-8 and Mi-17 helicopters are flexible high-pressure air lines used in pressurized air distribution, control-air circuits and pneumatic actuation systems. In maintenance work, these hose assemblies are normally selected by aircraft part number, hose type, pressure class, length, fitting configuration and the exact pneumatic system section where the line is installed.
On Mi-8 / Mi-17 family helicopters, pneumatic hoses may be used in main air supply lines, control command transmission circuits, auxiliary pneumatic networks, pressure indication lines and separate air-powered onboard mechanisms. Some assemblies operate in areas exposed to constant vibration, air pressure pulsation, temperature changes and mechanical movement, so a visually similar hose is not always suitable for replacement.
This category includes OST-standard pneumatic hoses, U-series hose types, reinforced high-pressure air lines and complete pneumatic hose assemblies for Mi-8, Mi-17 and related Mi-171 helicopter versions. Depending on the application, the hose may be supplied as a pressure line, control-air hose, auxiliary pneumatic line or ready-to-install assembly manufactured according to the required part number, drawing, sample or technical specification.
All pneumatic system hoses in this category are supplied only in factory new condition. Used, repaired, overhauled or serviceable hoses are not offered. For helicopter pneumatic systems, airtightness, reinforcement condition, pressure resistance, fitting quality and material stability are critical for safe operation and future maintenance planning.
For MRO companies, repair plants and fleet operators, replacement of Mi-8 / Mi-17 pneumatic hoses is usually required during scheduled maintenance, overhaul, troubleshooting of pressure loss, pneumatic system repair, control-air circuit servicing or long-term fleet support programs. Correct selection often depends not only on the helicopter model, but also on modification, installed equipment, routing and exact connection points within the pneumatic system.
Aviamisto supplies Mi-8 and Mi-17 pneumatic system hoses, high-pressure air hose assemblies and related helicopter spare parts for operators, MRO organizations, repair facilities and aviation 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.
