[T3] AN fittings

[Hal Sullivan]

Other than being a PITA to assemble, I've never had a problem with the 
Eaton/Aeroquip Socketless hose/fitting system.   It doesn't have the 
fancy/shiny stainless braid or teflon lining to the hose that screams 
"hot rod!" and the fittings are plain boring brass, but it was very 
reasonably priced for the pieces at the local hydraulics shop and in ten 
years I've had no leaks and no failures.
