Rejection and replacement of hose or hose assemblies after inspections are based on the standards normally specified in the applicable maintenance instruction manual, maintenance requirement cards, and depot-level specifications. Where rejection standards are not specifically outlined or if doubt exists as to the acceptability of a hose or hose assembly, replace the hose or hose assembly.

NOTE: Teflon (PTFE) hose assemblies are replaced only on a conditional basis.

Hose and hose assemblies fabricated from age-sensitive materials are subject to deterioration by oxygen, ozone, sunlight, heat, moisture, or other environmental factors. These types of hoses and hose assemblies should be stored in a dark, cool, dry place protected from circulating air, sunlight, fuel, oil, water, dust, and ozone (ozone may be generated in an atmosphere where electricity is discharged through oxygen or ambient air). Store hose or hose assemblies by sealing both ends of bulk hose. Cap or plug each hose or hose assembly. Store hose or hose assemblies on racks that support and protect them. Store hose or hose assemblies so that the oldest items are issued first.

Do not store hose or hose assemblies in piles. Improper storage will cause accelerated deterioration due to both heat and moisture factors.
