- Description
This category contains aviation hose assemblies recorded in the supplied lists for the Antonov An-12 aircraft and its modifications. The spreadsheet contains 116 unique positions. Of these, 115 exact ciphers and corresponding newer normal/OST references were cross-checked against the supplied technical document; one additional cipher appears only in the spreadsheet and is therefore catalogued without an inferred hose type or working medium.
The documented older cipher or drawing reference is used as the primary Product Name because it identifies the requested assembly precisely. When a newer normal is provided, it is retained with its spaced OST1 reference as an alternative designation. Confirmed Type M, Type U or Type P construction and approved working media are added only for positions matched to the technical document.
Products share an An-12 source-list application but are not presented as interchangeable. Different lengths, suffixes, prefixes, fittings and drawing references remain separate products. Four ciphers also occur in existing Aviamisto lists for Mi-8/Mi-17 or Il-76; those products are linked to the An-12 category instead of being duplicated. Before ordering or installation, verify the complete designation, dimensions, fittings and installation position against the applicable aircraft documentation, product passport and removed sample.
