Flexible Hoses and Hose Fittings
Maintenance or overhaul work of the flexible hoses should be performed in accordance with the hose
manufacturer’s service inf ormation and service bulletins.
Hoses and hose assemblies should be visually checked during each inspection.
Pay attention to:
- Leakage
- Separation of cover or braid of the inner hose
- Hardening or lack of flexibility
- Cracks
- Surface damage from hose clamps or supports
If any damage is found, replace the entire hose assembly.
Obtain a new hose assembly of the correct type, size and length.
Flexible hoses must not be twisted on installation; this could result in lower life times.
When replacing flexible hoses do not reroute the hoses, as this could result in different bend radius.
Bends that are too sharp will reduce the life time of the hose.
Fire-wall bulkhead fittings are steel, all hose fittings in the oil, fuel, brake and smoke systems are made of
aluminum alloy.
Unless otherwise stated, fittings are AN-types.
The dash number following the AN number indicates the suitable hose size in 16th of an inch.
This size measures the inner diameter of the hose.
The material code letter (D) follows the dash number, for example: AN823-10D.
