Hoses and Hose-kits

Postby criffus » Wed Apr 01, 2009 3:31 pm

Hey all...
I'm looking for hoses during my FW-Fwd refurb.
I searched the forum and didn't see much. ('doesn't mean it's not there! :roll: )
Anyway, I need fuel hoses, and the whole mess. Oh, I have new oil cooler hoses.
Anyway, can anyone point me in the direction of a good "kit" for O-540 in a 61-250?
I do NOT want anything with that black cotton on it. I don't know what advantages that stuff might have, but I just don't like it. I'm thinking more like stainless braided (aeroquip 666) and/or that nifty blue silicone. (teflon inner)

Any words of wisdom appreciated...
-Chris

Chris,
Teflon with firesleve...the only way to go (under the firesleve will be stainless braided outer aeroquip hose, with teflon innards). Measure your old hoses, and send the measurements to any hose shop. Tell them what you want, and they will make them for you. Once you have the hoses made at a proper hose shop, there will be a code on the band. That code can be used to reorder the hose anytime you may need one in the future.

I used http://www.aircrafthose.com/ .

Supply them the Piper number and they will make the hose.

Ken,
That only works if the plane is 100% stock in configuration. Most aren't at this point. Also, the Piper part number will not yield firesleved teflon hose. Don't put rubber hose on the plane when you can upgrade to a 100% solvent resistant, non hardening hose, with firesleve.

We shipped ours to Aviall, here in long beach CA. They use the exsisting connectors and fabricate new firesleved hose. Turn around was about a week. 61 250

Zack, I may be forgetting something, but I am sure I just provided the piper part no. for fuel and oil cooler lines. I requested the Teflon hose and received them. Was very satisfied.

Chances are, if you are reusing the same fittings, you didn't get Teflon. They use different fittings from the medium pressure Aeroquip 303 or Stratoflex 111 hose.

IMX, firesleeve is key regardless of the type of hose. It extends the life of the hose by a factor of at least two. I am just replacing my hose after 15 years, and it is still airworthy, but it is a cheap precaution, especially as I make them up myself.

Ken,
If your plane is stock in its configuration, then that is a good way to go. My point is that if you have done anything to move components or reroute hoses, such as cowl mods, exhaust mods, baffle mods, anything that could have altered the length of the hose required over the years since the plane left the factory, then it is best to measure, or send the hoses off as a sample to be sure you get what you really need back. Nothing is more frustrating than getting "hosed" by having one a little to long or worse a little to short....:-)

As Kristin says, Firesleave!!!! Use it! Just because it wasnt required on our planes, it may save your life one day, let alone the increased service life to the hose itself. I also highly recommend using the highest quality parts available. Teflon hoses, like fine wire plugs, will pay for themselvs over time. This is a case where spending less now will cost you more in the future...

-Zach
