 |
|
Can I connect aluminum AN fittings to steel hose ends? I am
planning on using Earl's Speed-Flex hose with Speed-Seal hose ends on
my Avid Mark IV with Grove gear and Matco brakes. Will there be
corrosion
from the mating of dissimilar metals? Thanks. |

I have the exact configuration on my Zenith 801 experimental. Been
that way for 4 years and I just finished my conditional inspection
this week. Virtually no sign of dissimilar metal corrosion... YMMV

Short answer: no problem.
Long answer:
Aluminum fittings are already corrosion-protected (either anodized or
some other treatment). In addition, there is usually a small amount of
oil or some other lubricant on the fitting, which stops water intrusion. |

Not familiar with the Earl's hose ends. Are those for
aircraft or automotive? Aircraft fittings have a 37 degree flare,
autos have a 45 degree. Not compatible at all.

As I recall, Earl's started their business selling surplus aviation
hoses and fitting to the auto racing crowd. They have since expanded
upon that base by engineering and having manufactured their own
compatible products.

A lot of the racing guys use AN stuff, rather than automotive, since AN
is available in aluminum. |
