6-20-250 ОСТ1 13815-81 hose for Ka-27 and Ka-32

6-20-250 ОСТ1 13815-81 is a hose position included in the supplied component list for the Kamov Ka-27 and Kamov Ka-32 helicopter families. The list confirms the designation and its association with these aircraft, but it does not identify the exact onboard system or working medium. For that reason, the product is described simply as a hose and should be matched to the helicopter documentation before installation.

A hose provides a flexible connection between installed components where a rigid line may not accommodate routing, vibration or limited relative movement. This general function does not establish whether this exact item belongs to a hydraulic, fuel, oil, pneumatic or another circuit. The approved illustrated parts catalogue, drawing and maintenance documentation remain the controlling sources for the installation position.

Identification and drawing reference for 6-20-250

The full ordering reference combines normal 6-20-250 with ОСТ1 13815-81. The drawing reference recorded in the source list is: 192. When more than one drawing reference is shown, the entries have been consolidated on one product page because the normal and OST designation are identical. This avoids creating duplicate catalogue pages while preserving the source identifiers that may be useful during a technical inquiry.

For ordering, use the complete designation exactly as shown in the product title. Similar-looking hoses from the same helicopter can differ in length, fittings, end orientation, construction or approved installation. A match by appearance alone is not sufficient, and a related hose must not be treated as an interchangeable replacement without documentary confirmation.

Installation checks and documentation

Before installation, compare the designation, drawing reference, end fittings and physical configuration with the removed item and the applicable aircraft records. Inspect the flexible body, ferrules and connections for storage damage, contamination, corrosion, cracking, deformation or other visible defects. Routing, bend radius, fitting orientation, tightening and clearances must follow the current Ka-27 or Ka-32 maintenance instructions.

The exact working pressure, test pressure, temperature limits, material, dimensions, mass, storage life and service life are not stated for this position in the supplied list. These parameters should be taken from the product passport, applicable OST, drawing or approved helicopter documentation when available. They are intentionally not inferred from neighbouring hose designations.
