Hoses for An-2

An-2 aviation hoses are indexed here for fuel, oil and air-system enquiries. The category provides two practical identification routes: normal-based designations that retain an OST1 reference and aircraft hose numbers from the 4575A or related families. It helps match a known record to an individual product card without treating all flexible assemblies on the aircraft as one specification.

Search by normal, OST or aircraft hose number

A complete normal may contain groups that describe the recorded execution and length, followed by the applicable OST reference. Other positions use an aircraft designation with letter and dimension groups. Keep the original separators and every suffix when searching. A near match can refer to a different assembly even when the visible hose and fittings appear similar.

System assignment is a starting point

Fuel, oil and air labels narrow the catalogue but do not define pressure, material, fitting orientation, dimensions or installation location for every product. Those details must remain tied to the exact Part Number and the applicable An-2 documentation. The category therefore avoids a blanket claim that every listed hose is certified, in stock or approved for every aircraft modification.

• provide the full Part Number, normal and OST notation;
• state fuel, oil or air system when it is known;
• identify the An-2 modification and installation position;
• add quantity, destination and required supporting documents;
• send a label photograph, removed sample image or catalogue extract.

Request an An-2 hose position

Use the exact product page to request confirmation of identification, available condition, delivery set, documentation, price and lead time. Similar products and category links support navigation only and do not establish substitution. Browse the parent Aviation Hoses section for other aircraft types, or use the main components catalogue when the requirement includes non-hose items.
