Hoses for An-72 / An-74 / An-124

An-72 aviation hoses share this catalogue section with positions recorded for the An-74 and An-124. The source lists use several identification formats: aircraft drawing numbers, ciphers, normals and OST references, with both rubber and fluoroplastic configurations represented where that construction is documented. Grouping the three aircraft families makes a shared exact number easier to find; it does not make different products interchangeable.

Drawing number, normal and OST

Use the identifier that appears in the applicable aircraft record and compare every character on the product page. When an exact Part Number occurs in more than one confirmed list, the card can preserve the relevant aircraft relationships. Similar numbers, alternative lengths or different standards remain separate unless the underlying source establishes the connection.

Shared applicability is not a substitution rule

A category label describes how the catalogue is organised. It does not approve one assembly for another aircraft, define a common installation point or override the illustrated parts catalogue. Material and construction wording is retained only for the exact positions for which it was recorded.

• specify An-72, An-74 or An-124 and the modification;
• copy the complete drawing, cipher or Part Number;
• include the normal and OST notation when shown;
• state quantity, destination and required paperwork;
• attach the source-list extract or removed-hose images for comparison.

Preparing a quotation request

Submit the exact product card together with the available aircraft context. The request is then reviewed for identification, condition, documentation, commercial terms and lead time. Use the main aircraft hose catalogue to switch to another airframe family, or the parts catalogue for requirements beyond hoses.
