- Description
Hydraulic system hoses for Mi-8 and Mi-17 helicopters are flexible pressure and return lines used in the main and auxiliary hydraulic circuits of the aircraft. These hose assemblies work with hydraulic fluid under load and are normally selected by aircraft part number, pressure class, hose length, fitting configuration, installation point and the exact hydraulic system where the line is installed.
On Mi-8 / Mi-17 family helicopters, hydraulic hoses may be used in pressure supply lines, return flow circuits, flight control hydraulics, actuator connections, braking sections, landing gear-related hydraulic lines and auxiliary hydraulic equipment. Some assemblies operate in areas with constant vibration, pressure pulsation, temperature changes and mechanical movement, so a visually similar hose is not always a correct replacement.
This category includes OST-standard hydraulic hoses, U-series, MT-series and 8A-series hose types, high-pressure aviation hoses, return lines and complete hydraulic hose assemblies for Mi-8, Mi-17 and related Mi-171 helicopter versions. Depending on the application, the hose may be supplied as a reinforced pressure line, a low-pressure return hose, an actuator connection line or a ready-to-install assembly manufactured according to the required part number, drawing, sample or technical specification.
All hydraulic hoses in this category are supplied only in factory new condition. Used, repaired, overhauled or serviceable hoses are not offered. For helicopter hydraulic systems, storage life, reinforcement condition, sealing quality, pressure resistance and compatibility with hydraulic fluid are critical for safe operation and future maintenance records.
For MRO companies, repair plants and fleet operators, replacement of Mi-8 / Mi-17 hydraulic hoses is usually required during scheduled maintenance, overhaul, hydraulic system repair, troubleshooting of pressure losses, actuator servicing, braking system work or long-term fleet support programs. In many cases, correct selection depends not only on the helicopter model, but also on modification, installed equipment, routing and the exact connection points within the hydraulic system.
Aviamisto supplies Mi-8 and Mi-17 hydraulic system hoses, high-pressure aviation hose assemblies, return lines 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.
