Joe,
Stick to the Erals fitting. They are much easier than the Aeroquip fittings. Also, I have found that on smaller dia. that tape then a large pair of linesman pliers works well, reinforced package tape works best. Using a multi purpose
oil also helps. Don't forget to flush out your hoses after they are assembled . The trick for the Aeroquip ends is to start swearing early and band aids for your fingers.
