Brake pipes
« on: August 13, 2017, 01:19:51 PM »
Ordered and received new brake pipes from MM for the 60 mini (original brake config).  The new pipes had double flare (right photo) and originals had bubble flare (left photo). I called MM and they said they woukld work on rewtained fittings such as brake cylinders etc. Was skeptical as it is counterintuitive to repalce amale flare with a female flare and expect no leaks.
Anyone have experience with this?

Seems wrong to me too, can you post a good pic of where the pipe attaches? I suppose the edge of the flare will contact the inner part of the hole and seal around the edge, but without seeing the hole it goes into that's just a guess.....it is a fairly soft and malleable metal in the pipes.

I haven't seen bubble flares that I can recall.......you sure it's a flare and not a ferrule on the end of the pipe?

Toss em on and see if they leak.  Or reflare them.  I buy rolls of pipe and bags of fittings and simply make my own.

So I tossed em on. Initially they leaked but I tightened them as much as I dared then 1/4 turn more to pretty tight. Didn't leak with rube goldberg laek check.  I looped one pipe using the Tee on the front bulkhead. old ones didn't require as tight so may just re-use old pipes and clean them up. They look good no rust.
