We've been playing with the Beringer conversion a little bit for the RV14 and 14A, as well as for the other RV models. To use our banjo hose ends, we use a -3 teflon hose. It works well, and in the case of the 14A it means little modification to route the hoses to the main gear fittings. WE have -3 AN hose ends on the airframe fittings, and 10mm banjo CRIMPED hose ends on the Beringer accessories, like the master cylinders, calipers, parking brake valve, and for those that use it, the antiskid valve.
When using Beringer's re-usable hose ends, you can actually route the hoses through the spar, then terminate the ends, being careful to do it correctly to provide a leak-free assembly. In our package, we are providing the AN adapter fittings to change from -4 to -3 at the reservoir, and the gear/firewall passthroughs.
We have several of these packages out there for builders to use, both for the RV14 and RV14A. Shout out to Ryan McGarty in Charleston, SC, that allowed us to see his 14A and do a mockup install. We also have a few 14's, one with a parking brake and an antiskid valve installed, but I dont have any pics as of yet.
Honestly there is an advantage to using the "make your own hoses" that Beringer provides in their package. That is not everyone will place the parking brake valve, and/or the antiskid valve in the same locations as everyone else. (Not yet anyway). On the antiskid clients install, we felt that, gee if you are going to have an adjustable valve, you might as well locate it so you can reach it to adjust it. So--in his install we wanted him to mount it at the throttle cable mount brackets. That way the thumbscrew was accessible, and the hose routings were out of the way.
With our package, YES we can make the hoses any length you want, we just have to know where you are mounting the valves. YEP--one of these days we'll come up with a final location for these that is universal to all builders.
