Hi folks,
I bought some Aeroquip 303 hose and fittings for same, to use in place of the plastic brake line in the cockpit of my RV-7. I also have the correct mandrels required to install the fittings. However, I'm having a little trouble with the assembly, in reference to the instructions in the ACS catalog or this copy here. I screw the hose into the socket, back it off a quarter turn, secure the socket and hose in my rubber-jawed vice, thread the mandrel into the nipple and tighten, and smear Lubriplate everywhere. So far so good. However, I often have trouble getting the mandrel/nipple combination far enough down into the hose for the threads to engage the socket, no matter how much pushing/twisting/threading I try. The instructions just say "screw nipple into socket and hose using wrench on assembly tool" like it was no big deal, which makes me thing I'm doing something obvious wrong. Is there a secret?
I'm just making practice hoses now; I'll take the real pressure-holding hoses to a hose shop for testing. I may have to have them make up the hoses for me too, but I'm hoping I can figure out the secret.
thanks,
mcb
