1667-2U6-15-450 hose identification and aircraft applicability

1667-2U6-15-450 is a Type U rubber hose assembly with cotton braids and fittings recorded in the supplied lists for the An-24, An-30. Confirmed applicability on this page: An-24 / An-30. The designation and aircraft applicability were cross-checked between the supplied aircraft lists where corresponding rows were available.

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: Static pressure / altitude 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: 1667-2U6-15-450; 3-6-1-480 OST1 10843-85. Alternative search forms: 3-6-1-480 OST1 10843-85; 1667 2U6 15 450. Technical specification or construction type: TU 38.0051515-92. Working medium for the confirmed group: Oils AMG-10, MK-8 and transformer oil; fuels T-1, T-2 and TS-1; gasoline, water and air.

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.
