4580А-У18-405 hose for the Il-76 Fire-Protection System

4580А-У18-405 is catalogued as a Fire system hose for the Ilyushin Il-76 aircraft family. The Latin search form is 4580A-U18-405. The supplied source confirms the exact normal designation, Il-76 association and placement in the fire-protection system. These verified identifiers form the basis of this product card; technical values not present in the source have not been reconstructed from similar hoses.

A hose assembly provides a flexible connection where a rigid pipeline cannot conveniently accommodate routing, vibration or limited relative movement between installed components. That general function explains the use of flexible assemblies on an aircraft, but it does not establish the exact connection points, fitting orientation, pressure class or working medium for this individual designation.

Function within the Fire-Protection System

The system classification comes directly from the supplied Il-76 hose list. It is useful for maintenance planning and catalogue navigation because it narrows the search to the fire-protection system. The list does not identify the precise circuit branch, adjacent units or installation zone, so those details must be confirmed against documentation for the relevant aircraft modification and production series.

Hoses that appear similar can differ in length, internal diameter, reinforcement, ferrule construction, thread, fitting geometry and end orientation. A common aircraft type or system does not make two positions interchangeable. Selection should be based on the full normal designation and the applicable drawing or parts catalogue entry, not on external appearance alone.

Drawing and identification of 4580А-У18-405

The supplied list records aircraft drawing 6610.510.000 for this exact position. The exact Cyrillic normal is retained in the Product Name. A Latin-character search form is included in Technical Details so that procurement teams can compare different document systems without replacing the original designation.

When preparing an inquiry, compare the complete marking with the aircraft records and any readable information on the removed assembly. Photographs of the flexible body, both end fittings and their orientation are especially useful. If the markings are incomplete, the aircraft modification, installation area and available drawing reference should be provided for additional identification.

Technical verification before installation

Before installation, the hose should be inspected for cracking, deformation, contamination, corrosion, damaged threads, loose ferrules or storage damage. Routing, minimum bend radius, fitting orientation, tightening requirements and clearances must follow the current Il-76 maintenance instructions. The card does not replace approved maintenance documentation or an incoming inspection.

Reliable public values for dimensions, mass, working pressure, proof pressure, temperature range, material, storage life and service life were not found for this exact normal. These values should be taken from the product passport, the applicable drawing and approved aircraft documentation. Parameters from another Il-76 hose are intentionally not copied into this position.

Ordering 4580А-У18-405 and related Il-76 hoses

4580А-У18-405 is listed in the Aviamisto Hoses for Il-76 category and is offered on a pre-order basis. An inquiry should include the full designation, required quantity, aircraft modification and documentation requirements. Where a drawing is available, include it in the request to reduce the risk of selecting a visually similar but different assembly.

For purchasing traceability, keep the original designation, drawing reference and aircraft application together in the inquiry and subsequent records. This makes it easier to compare a supplier quotation with the maintenance request and prevents a Latin search form from being mistaken for a newly approved Part Number.

Related catalogue positions include 4568А-У4-170, 4568А-У4-190, 4568А-У4-260, 4568А-У4-270. These links connect products recorded for the same aircraft family and help users navigate the Il-76 hose catalogue. They are not replacements, equivalents or interchangeable assemblies unless the controlling technical documentation explicitly confirms that relationship.
