Some Manufacturers have specific change out requirements for specific hoses. The FAA has issued AD’s (Airworthiness Directive) for hoses relating to specific aircraft. All of these requirements must be taken into consideration when evaluating when hoses need to be changes. When Is An Old Hose OLD? All Hoses/Hose Assemblies have three (3) Phases of Life: Acceptance, Shelf And Service. PTFE (Teflon®, Dupont Trademark) is non-aging RUBBER (except AQP) Acceptance: Shelf: Service: = Notes: 1. Total above can be 20+ years (8+5+7) 2. All hose, including PTFE, takes a “set”, that is, it becomes formed to the installed configuration (bends, etc.). Moving a “set” hose, in order to remove some other unit for example, may cause damage, thus terminating the life of an otherwise properly functioning “live” hose. 3. AQP (AE701) should be considered “essentially non-aging”; silicone exceeds 20 years shelf life and lasts 3 to 5 times longer than Buna-N (hot oil circulation).
