Description
6-4-300 OST1 13820-81 hose identification and aircraft applicability
6-4-300 OST1 13820-81 is a Type M rubber hose assembly with textile braid and fittings recorded in the supplied lists for the An-32. Confirmed applicability on this page: An-32. The controlling Type M hose standard is recorded as OST1 13820-81; conflicting source spellings are retained only as alternative references.
The item is treated as a flexible connection within an onboard pipeline. It can accommodate routing, vibration and limited relative movement between connected elements, but exact connected units, installation points and flow direction are not added when the source materials do not identify them.

Function in the documented onboard system
Recorded system assignment: Oil system. This classification identifies the applicable system section but does not independently establish a circuit branch, physical installation point or interchangeability with a neighbouring position. One aircraft type can use visually similar assemblies that differ in length, fittings, reinforcement and operating limits.
The technical role of the hose is to maintain a sealed flexible path for the approved working medium between connected parts of the system. Allowable pressure, temperature, bend radius and service limits for the exact execution must come from its passport, drawing and current documentation for the applicable aircraft.

Recorded designations and technical references: 6-4-300 OST1 13820-81. Alternative search forms: 6-4-300 OST1 10820-85; 6-4-300 OST1 13820-85; 6 4 300. Technical specification or construction type: TU 38.0051515-92. Working medium for the confirmed group: MK-22, MS-20, MK-8 and transformer oils; approved mixtures recorded in the supplied technical list.
Retain every digit, point, hyphen and letter suffix in an inquiry. Different lengths and base normals are catalogued as separate products. A matching dimension, appearance or partial designation does not demonstrate that another hose is an approved replacement.
Inspection, installation and documentation
Incoming inspection should verify the Part Number, normal, OST reference, YOM, flexible body, ferrules, fittings, protective caps and internal cleanliness. Check for cracking, kinking, swelling, corrosion, contamination, damaged threads and evidence of unsuitable storage. The representative image shows a group of aviation hoses and does not confirm the individual marking of a particular supplied unit.
Compare the removed and supplied assemblies by controlled length, internal diameter, connection hardware, fitting angles and relative orientation. An installed hose must not be twisted, sharply bent, routed against an edge or hot surface, or interfere with adjacent equipment. Use the aircraft installation documentation to establish bend radius, clearances, supports and clamp positions.
Reliable dimensions, mass, exact operating pressure, temperature range, assigned life and storage limit for this execution were not found in the available sources. These values must not be copied from a neighbouring position or inferred from the photograph; confirm them through the product passport, certificate, drawing and aircraft documentation.
