Brake and clutch reservoirs

[TGN]

The outlets on my reservoirs are approximately 8.5mm and the hard pipe coming from the master cylinders is 6mm. Kelsey Hayes original set up.

I’m fairly sure I’ve seen the pipes sweating previously, so I’m not confident they’re of the correct composition for brake fluid. And when I drained the old fluid, anything from that vicinity was quite black.

Which diameter epdm pipe should I use to join the two? I’m either squashing and clamping 8mm pipe onto a 6mm tube, or will I be fighting a losing battle trying to stretch a 6mm hose onto an 8ish mm plastic outlet?
I might try and use a hydraulic flaring tool and increase the bore of the metal pipe, but I think it’s possibly steel original rather than cunifer, so may not be successful.

Here is one solution..... or Cohline 7mm i/d hose viewtopic.php?f=3&t=20327

Thank you Steve. The illusive thread that doesn’t appear with any search, until you post.

Not sure 7mm is going to go on the reservoirs without a fight.

From what I’ve read fuel pipe isn’t compatible with brake fluid, and it appears that’s what Rory used.
