Brake pipe flares
adam_moore - 4/10/04 at 02:18 PM

Hi,

can anyone tell me what type of flare is needed on the end of a brake pipe that is conencting to a male bulkhead flexible hose (convex seat)?

Is it a double or a single flare (V shaped in section)?

Thanks

Might be able to help but need a picture of the end of the flexible hose - just to clarify the situation

it will have opposite profile - ie single flare.

this is the one that has a domed shape, rather than a belled out shape.

Standard hose fittings are usually male threaded (banjo fittings being "special".
So the mating pipe fitting has to be female, and this requires the "double op" flare, where the second part of the flare is folded back against the first flare section (by the 2nd op.).
Male threaded pipe fittings need the "single op" flare, which, as Mr. Gusto described, has a domed face to engage the bottom of the associated port.

Have just been doing my brake pipes - again!! It's so easy to cut these ***** pipes too long/short, especially over the longer runs (where unexpected bends soak up the added length you already provided for!!).

LoL

What does everyone use to do the flares? Hand held cheapy tool or hold-in-a-vice-more-professional-tool? Where is the best place to get one?

Started with a handheld screw-in type. Worked (with practice and grease) but wasn't great.

Was then lent a Sykes-Pikavant pro job and it's amazing!
1. Clamp pipe
2. Pull handle
3. Remove finished brake pipe!

Bet it wasn't cheap though!

All the best.
