brake fittings

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.

Earl's is available in 37°
