4568A-U4-440

4568A-U4-440 hose for the Mi-2 helicopter

4568A-U4-440 is a Type U rubber hose assembly with cotton braids and fittings recorded in the supplied hose lists for the Mil Mi-2 helicopter. The designation matches in both supplied source lists. The card keeps the documented cipher, normal and standard without merging the item with visually similar executions.

The assembly provides a flexible connection in an onboard pipeline and can accommodate routing, vibration and limited relative movement between connected elements. Exact connected units and installation points are not added when the supplied documentation does not identify them.

4568A-U4-440 application within the Mi-2 system

Recorded system assignment: Main rotor system. This classification links the product to the relevant section of the technical list, but it does not independently establish a particular helicopter modification, circuit branch or physical installation point.

Hoses used on one aircraft type may differ in length, internal diameter, reinforcement, thread, fitting geometry and end orientation. Related catalogue positions therefore support navigation and are not presented as replacements, equivalents or interchangeable assemblies.

Cipher, normal and OST identification

No separate normal is recorded in the source. No separate OST is recorded for this position. The source list records 3 pc for this designation. This is a reference-list quantity and not an Aviamisto stock balance.

Every digit, hyphen and letter suffix should be retained in an inquiry. Different lengths, prefixes and suffixes are catalogued separately. A convenient search form does not replace the source designation or prove interchangeability.

Hose construction and technical verification

Available product type: Type U rubber hose assembly with cotton braids and fittings. Technical reference or construction type: TU 38.0051515-92. Working medium: Oils AMG-10, MK-8 and transformer oil; fuels T-1, T-2 and TS-1; gasoline, water and air. These details are carried over only from a source row or group matched to the exact designation.

Reliable dimensions, mass, minimum bend radius, operating pressure, temperature range and connection sizes for this exact position were not found in the supplied sources. Confirm them through the product passport, drawing and applicable Mi-2 documentation.

Before installation, inspect the marking, flexible body, ferrules and fittings for cracking, kinking, corrosion, contamination, damaged threads or storage defects. Compare the removed and supplied assemblies by length, diameter, connections and relative orientation of the ends.

Incoming inspection should also verify YOM, protective caps, internal cleanliness and accompanying documents. The representative photograph shows a group of aviation hoses and does not confirm the individual marking of a particular supplied unit.

Installation suitability is checked by more than overall length. Compare the flexible-section length, ferrule positions, thread type and size, fitting angles and end orientation. An installed hose must not be twisted, sharply bent, routed against an edge or hot surface, or interfere with moving equipment. Use the helicopter installation documentation to confirm bend radius, clearances and clamp locations.

Keep the connection ends capped before installation so dust, moisture and foreign material cannot enter the assembly. At receipt, inspect packaging, marking and visible storage condition. Storage life, assigned service life and calendar limits cannot be judged from appearance; use the passport, certificate and current documentation for the exact position.
