face=Arial>Double flare goes out and in again - it's probably the same as a
bubble<BR>flare (two countries divided by a common language!). The end
of a normal<BR>brake line is that. Yes, some couplers use an olive which
is a compression<BR>coupler and relies on friction with the pipe to stay
together. I had to<BR>hire the proper flaring tool to add a new bit to
the one piece line on a VW<BR>Polo we had - only the rear bit had rusted, and
removing the whole line<BR>would have been a harder job. My 'cheap'
flaring tool was OK for copper but<BR>no good to flare the original steel pipe
for the proper coupler.</FONT></DIV>

<DIV>Over here, we have a single flare (for copper water lines and such),
double flare (most domestics use these), and bubble flare (which is in
between) and used on German cars such as our own, and Japanese cars.</DIV>
<DIV>We also have people who use compression fittings, although they really
shouldn't be used on cars (but still find there way there). To make a
bubble flare, you start with a single flare, then add in a "bubble flare tool
insert" that basically rolls the outer edges back into itself (like a double
flare), but doesn't go all the way.</DIV>
