Had to replace the braided, stainless steel hoses on my 4905 with 871 that run from the air govenor up to the firewall. One is 1/4" pipe fitting and the other is 3/8" with swivel connections on all
ends. One is 30" long and the other is 28".
I think they saw me coming, as they two cost me
$82.00. Does anyone know if they stuck it to me or is this stuff really that expensive. There are
other hoses of this type on the engine and some of them are 1-1/4" and some 1". It would take me a year of social security to replace a couple of those. Anyone else had to make this repair? |

Sounds about right to me. Try Wicks Aircraft or Aircraft Spruce to get the goodies to make your own, you could probably save $15.00 and you have to have the tool at $69.50 to do it. DO NOT attempt to make them without it, or the end either gets clogged with folded over rubber, or(horrors!) comes off!!! Cheers...JJ |

you didn't say did they rupture or did they melt???? bought a bunch of transits one time and one of them melted the small air lines when we put in batteries and tried to start the bus bad ground wire melted the hoses...just asking gg04 |

GGO4.One of them ruptured so I replaced both of them.Thanks for the tip JayJay. Guess I'll let
them make any I may need in the future. Just seemed like robbery to me, when a new air govenor only cost $14.00.
This is a great site. I have learned a lot, so many times, by absorbing the information posted here. |

Be careful if you use aircraft hoses with flair fittings. Aircraft use 37.5 degree flair, not 45 degree. |

Braided stainless steel hoses are used for abrasion. They contain rubber hose and are no more resistant to heat than common rubber. With the stainless steel braid covering the hoses you can’t tell if the hose is old and ready to go.
In aircraft use all hoses are replaced on a very conservative time schedule. We need to see and maintain our hoses.
I hate them. I prefer to carefully route and support common rubber hoses. I can replace them at the first sign of age with hose readily available at most any auto supply or hardware source.
Yes, I always have a contrary opinion!

On the other hand, some braided stainless steel hoses, like the one typically running from the compressor's output to the first air tank, will be made of teflon inside and the stainless braid on the outside so it can handle the pressure, having nothing to do with abrasion. This type of hose can handle much higher temperatures than stainless-covered rubber hose which in this application would probably fail from the heat generated from the act of compressing air. So not all stainless braided hoses are created equal.... as far as brakes are concerned though, it's best to get OEM factory replacements for any hose in the system, or go to a professional hose company that deals in truck parts, because inncoently replacing a brake system hose with a nice new one of the wrong type could get you killed....

Peter... I agree with you about the more mundane use of hoses. The service we put then to obviates the need for some of the the more esoteric types of equipment that the manufacturers installed when new. Cheers...JJ |

The aircraft supply houses stock SAE and Aircraft standard fittings in Aeroquipt hose and adapters.Stainless and brass covered and the plain vanilla braided rubber. Fittings come in aluminum, steel , stainless steel and brass. 'Ya just 'gotta be smarter than the equipment mate! ...JJ |

Bill I know you are talked out on this subject but on trucks it was the law that they had copper from the compressor because of the high heat involved with the compressed air , think they finally went to the SS for the flex and still handle the heat. Jim |
