• Eaton Aeroquip AE701

  Eaton/Aeroquip’s 701 hose is widely used for aircraft fuel and oil lines where flexibility and light weight are prime considerations. The hose is made with a synthetic rubber inner tube with two layers of stainless steel wire braid reinforcement. Because of its lighter weight and lower operating pressure than type 303 hose, it is not recommended for hydraulic lines. AE701 hose has no shelf life and is the upgraded version of 601 hose. Operating temperature range of -65F to +300F. Used with Aeroquip 816 hose fittings. View AE701 Data Sheet

  Questions	Answers
  My hose has orange firesleeve, can I replace it with the brown silicone integral firesleeve?	Yes, select AE466 for the hose type and proceed with other specifications from the dropdowns.
  My hose is 10 years old, do I really need to replace it?	Though your hose may continue to be serviceable at the moment, it is recommended to replace hoses after 8 years or at overhaul of the engine.
  My mechanic told me that Teflon hoses are lifetime, is that true?	No, regardless of hose type, it is recommended to replace the hose after 8 years or at overhaul of the engine.
  My aircraft's engine is being overhauled and hoses were replaced 5 years ago, do I need to replace them?	We recommend sending your hoses to our hose shop for inspection, pressure testing and possible recertification. If the hoses pass, a second tag will be added to the hoses with the date of recertification and the hoses should be serviceable until they are 8 years old or next engine overhaul. This can be done at a fraction of the cost of new hoses. Any hoses that fail will be quoted and offered to be built new.
  Do you offer hose kits for specific airframe or engine models?	Though there is certainly some convenience in this, we have found the majority of engines are modified in ways that change the lengths and angles on hoses. Due to this, we do not offer hose kits. Please contact the hose shop to help identify your necessary hoses or send them in for duplication.
  Are there minimum lengths for hose types?	Yes, AE466 has a 6" minimum length. Rubber hoses tend to have a 4"� minimum length.
  My hose goes between the engine baffling and the firewall, does it need firesleeve?	All hoses within the engine compartment are recommended to have firesleeve.
  How can my hose be identified for replacement?	The surest way is to send your hose to our hose shop for duplication. If this is not an option, we recommend looking up the part number in your engine / airframe illustrated parts catalog. Providing our hose shop with the P/N on id band is an option however it is only successful if the proper P/N was put on the ID band. The original hose P/N may not be applicable if any modifications have been done to the engine. Lastly, hoses can be broken down by hose type, size, firesleeve or no firesleeve, length and angle of fittings.
  I want to install a transducer for fuel flow metering, what hoses will I need to install with it?	The length of the currently installed hose will need to be provided to our hose shop. Generally, it is recommended to install the transducer in the middle of the length of hose. The transducer length would need to be provided as that length will be deducted from the two hoses that will be installed to the transducer. If you want the transducer in a specific position within the engine compartment, the lengths of the two replacement hoses will be determined.
  Why do I need an angled fitting, can't the hose bend however I want it to?	Each hose type has its own maximum bend radius. If bent beyond that, the hose would be expected to crack rendering it no longer serviceable. Due to this, hoses use either a straight, 45 degree or 90 degree fitting.
  I have a drain / vent line that only has a fitting on one end. Do all hoses have to have a fitting on both ends?	We can build a hose with a fitting on only one end if that meets your application. Please contact the hose shop.
  Can you recertify my hose that isn't Eaton / Aeroquip brand?	No, the hose shop is certified by Eaton to only work with Eaton hoses. We would be happy to build you an Eaton equivalent of your hose.
  I selected the wrong hose on my order, what should I do?	Contact our hose shop immediately. If your hose hasn't been cut, we can try and accommodate the change. Otherwise, hose orders are non-cancellable and non-returnable as each one is custom made.
  I received my hose and my mechanic said I should have had firesleeve on it, do I need to order another hose?	Not necessarily. The orange firesleeve can be added over a straight fitting after a hose has been built. The firesleeve can be added and the proper P/N for the firesleeved hose will be on the hose tag. Please contact our hose shop and send us the hose.
  If I send you my hoses for duplication can I have them back?	Yes, we would be happy to send back your old hoses along with your new hoses. Many customers add tape to their old hoses identifying where they go on the aircraft. It makes sense for you to match that old hose with the new to know exactly where it goes.
