Subject: | Re: Aeroquip hoses |
Scott,
thanks for the info , probably like many I thought the aeroquip/
stratoflex hoses were the safest and most reliable solution , but if they
only last 5 years , its probably better to use the cheap neoprene and
replace at the same interval. I will do a major inspection of all my hoses
ASAP, as i am clearly on borrowed time .

According to the Q/A section on the ACS page 303 hoses should be replaced
every 5 years. Seems pretty conservative. I have read other places 10
years.
They have a lot of distributors that should be able to make a new set of
hoses based on the old ones. The end fittings are probably still good.
They are not too hard to do yourself if you get the mandrel tool from ACS.

I would stay away from the neoprene hose. Another option is the Teflon hoses
that last a lot longer. That is what the airlines use now.

Subject: | Re: Aeroquip hoses |
Scott
since i have all aeroquip/ stratoflex, its simpler for me to replace just
the hose and use the original end fittings , As you said , they are
quick to make up ,
>From a google search , Rotax engines also states that their rubber hoses
need to be replaced at 5 years.
Does anyone know which Service Bulletin Continental covers their rubber
parts under ? ( OC ? )
