Where to Buy hoses

[Mooney1401]

Looking to replace the hoses in my 77 M20J

Trying to find a place near home is proving difficult.

[M20F-1968]

I have a few new, fire sleeved and Teflon oil hoses which are new and unused from my rebuild project which are available.  If you let me know the length and specifications of the hoses you need I will check them and advise.  I can be reached at (617) 877-0025 and e-mail johnabreda@yahoo.com    I also have some hydraulic hoses that are also available.

 

Thanks,

John Breda

I've heard good things about PHT at http://www.aircrafthose.com/; they'll make kits or individual hoses to your specs, with or without firesleeve.  They're not too close to you, but they ship.  Is there a particular reason that you need someone close to home?

aircraft spruce make hoses to spec.

I called Spruce. They have a shop make them to spec. Stick with PHT or Sacramento Skyranch.  Only Parker Stratoflex, however, makes the 124J integral sleeve hose in the -3 size for the fuel pressure gauge.

what is the requirement for the fire sleeve ?

only hoses that have firesleeves are the oil coolers' and the fuel line

There was a discussion a while back about fire sleeve. It seemed some planes have it and others don't.  I installed the Lasar oil cooler relocation last year and the hoses it came with did not have fire sleeve. Then again the original oil hoses are very close to the exhaust and with the relocation kit they are not even close.

 

My IA is of the opinion that if they are close enough to the exhaust that a exhaust leak could burn through them then they need fire sleeve.  Otherwise he prefers them not to be sleeved so he can inspect them and determine the condition of them.  The fire sleeving can also conceal early stages of leaks or other problems that would otherwise be easily visible.

I'd prefer fireproof hoses in the fire zone. The 124J hoses meet the 15 minute fireproof rating, as well as the Teflon "on condition" replacement interval. . It may not be required, but the overall cost was not much more than a regular hose set.  Around 800$

Thanks. I like the steel brading style better.

 

As far as firesleeve, I just wish the teflon cover was not that uggly brown color. Red, yellow or blue would be my choice.

You can get them in blue

It's also possible to remove the hoses and take them to a hydraulic shop and use your fittings and have the hoses made. You can buy the hose and fire sleeve from chief or spruce and let your mechanic make the hoses. Easy job if have the hose and sleeve. Is a cheaper option than buying already made from shops.

Automotive and industrial hydraulic hoses use the 45 degree SAE fittings. Aircraft use the 37 degree AN fittings.  They may bolt up, but they are not interchangeable.  Another thing to consider is this, if ANY of those hose ends come loose in flight, best case you have a forced landing, and worst case, you are dead. There are fourteen hose ends on an M20J engine hose set.

 

I've seen some terrible advice about using non-firesleeve hoses in the fire zone, reusing hose ends and doing it yourself, and having an automotive shop crimp your hoses. Its 800$ for the best hoses you can buy. Its half that for a homegrown solution with no data tag.  With people routinely dropping 20-30 grand on the fanciest new panel mount gadgets, paint, and interior, it is amazing someone is willing to compromise safety to save 400$. Because thats what it is, less for less, but it can kill you faster than that dual magneto.  The other thread about engine failures reminds me of some of the causes of engine failures. most were caused by faulty accessories, systems, or maintenance. I can understand why.

 

Further, consider this. Those hoses fall under TSO C75, C53 and C42, which are heat and fire ratings,  and have a pressure test to twice working pressure ( 3,000 PSI) done on them before they are tagged and shipped. Now, is a NAPA hose shop, an A&P, or an owner capable of certifying they conform to the TSO and pressure test?

If you use your own hose fitting as they are screw on (most of them) you have the same flare. Most mechanics have flre tools for avition flare. Why pay more if you or your mechanic can make the same hoses. Just because these kits are made at aviation hose shop, doesn't mean technique for making the hose is different. People making hose dont have to be mechanics and don't necessarily know how they fit on the aircraft! As an A&P, if you can't make a hose easily, you shouldn't have passed your exam!

this is the world we live in ....

people are unwilling to pay for commodity items like hoses or gasoline since they are hidden. hoses are behind a cowling and the gas stays in the tank. when you fill a car you don't even see what you bought.

but they are ready to pony 1000's for the latest fancy Apple or Garmin device.

not criticizing anyone, i am guilty of that too. sometimes.

personally, i value the certification ring that a specialized aviation shop will put on the hose.
