6-20-1300 OST1 10852-72 hose for the Mi-26

6-20-1300 OST1 10852-72 is a Type RMB rubber hose assembly with thread braid and fittings recorded in the supplied hose list for the Mil Mi-26 heavy transport helicopter and the Mi-26T modification. The exact source designation is retained, while 6-20-1300 OST1 10852-72 is provided as a Latin search form.

The assembly provides a flexible connection within an onboard pipeline and can accommodate routing and operational vibration. The source does not identify the exact connected units, installation zone or flow direction, so those details are not reconstructed from other Mi-26 hoses.

Hose construction and confirmed working media

The source defines the construction as: Type RMB rubber hose assembly with thread braid and fittings. Technical reference: TU 38 105419-90. Listed working media: B-3V oil. These values belong to the documented group containing this exact row and are reproduced without adding unverified characteristics.

Not specified in the supplied list. Exact dimensions, mass, minimum bend radius, operating temperature, connection thread and fitting orientation are not provided for this designation. They must be checked in the product passport, drawing or applicable helicopter documentation.

Identification and standard for 6-20-1300 OST1 10852-72

The supplied list records OST 1 10852-72 for this position. In the Product Name, the normal and standard are separated by a space and are not joined with an additional hyphen. The Mi-26T list records 1 pc for this designation. This is a source-list quantity and is not an Aviamisto stock balance.

All dots, hyphens, digits and letter indices should be preserved in an inquiry. Hoses that look similar may differ in diameter, length, reinforcement and fitting configuration. A common construction type or working-medium list does not establish interchangeability.

Verification before Mi-26 installation

Before installation, check the marking, flexible body, ferrules and fittings for cracking, kinking, corrosion, contamination, damaged threads or storage defects. Compare the removed sample and supplied assembly by length, diameter, connection dimensions and relative orientation of the ends.

Routing, permitted bend, tightening requirements and cleanliness limits are governed by current documentation for the applicable Mi-26 modification. This product card supports identification, but it does not replace the product passport, illustrated parts catalogue or maintenance manual.

Incoming inspection should also compare the manufacturing date, protective caps, internal cleanliness and accompanying documents with the physical marking. Storage history and eligibility for installation must be assessed under the operator or repair facility procedure. A representative catalogue photograph does not confirm the condition of a particular supplied unit.

If the original marking is incomplete, record the removal location, fitting orientation and neighboring pipeline elements before disassembly. That evidence can help distinguish closely related executions, although the final selection still depends on controlling documentation. Dimensions, pressure limits or service life from another product in this category must not be transferred to this designation.
