zep Posted December 5, 2021 Share Posted December 5, 2021 I am keen to run my master cylinder to a remote reservoir with braided lines. The problem is that there are no threads in the master cylinder inlet, only these clamp on plastic things. What's the best way to adapt this to braided lines that I can thread in to the reservoir? My two thoughts have been using some kind of rubber bung and a push in adapter that is threaded on the other end, or welding on something threaded but was advised not to weld the master cylinder as it might warp.

mjrstar Posted December 5, 2021 Share Posted December 5, 2021 Assuming you are only looking for the look of stainless braid rather than any performance gain on the non pressurized side, you'd probably get away with some rubber lined stainless braided hose and clamps. Personally I'd run a rubber hose for this application and call it job done. Another option would be a machined stub that presses in with the - 3an or whatever nipple you desire threaded /welded to that, perhaps cooled slightly to make it an interference fit on installation.

zep Posted December 5, 2021 Author Share Posted December 5, 2021 Yeah, it's more for looks than anything else. Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted December 5, 2021 Share Posted December 5, 2021 heat shrink over the cut braid and a hose clamp would be my move unless you dont want a visible hose clamp. you can also get heat shrinkable hose clamps for radiator hoses, can probably get small ones too. that would be a clean way to do it gates power grip i would blow cold air through the hose/plastic fitting while shrinking though to hopefully prevent damage to the plastic nipple Quote Link to comment Share on other sites More sharing options...
zep Posted December 5, 2021 Author Share Posted December 5, 2021 Interesting. I assume that the gate powergrip clamps have some kind of adhesive in them. I wonder how that would react to the brake fluid if any managed to sneak around. It's not pressurised, though, so should be okay. Quote Link to comment Share on other sites More sharing options...
vk327 Posted December 6, 2021 Share Posted December 6, 2021 standard rubber lined braid with an fitting on the reservoir and these on the maser cylinder end ? https://nzkw.com/shop/hose-finisher/ Quote Link to comment Share on other sites More sharing options...

ajg193 Posted December 7, 2021 Share Posted December 7, 2021 Pretty sure there were some fake braided sleeves to go over rubber hoses in the design disaster or AliExpress threads a month or so back Quote Link to comment Share on other sites More sharing options...

I like the idea of a press-fit plug/stub. Thread it, weld in a nipple and be done. You could even machine an o-ring groove in it. 2 Quote Link to comment Share on other sites More sharing options...

I had after posting considered the o-ring option Richie von Snoozin suggests which I think could well be a nice addition. Quote Link to comment Share on other sites More sharing options...

zep Posted December 8, 2021 Author Share Posted December 8, 2021 Ah yeah. That's a good idea. Could easily weld a dash fitting on the top as well. What's the deal with determining the OD of the push-fit in relation to the master cylinder inlet ID? Quote Link to comment Share on other sites More sharing options...
Muncie Posted December 11, 2021 Share Posted December 11, 2021 I've done this exact thing on a SU carb float. Chop the barb off the plastic hose tail and tap your AN fitting to accept a push on fitting. Works a treat and looks alright if you cut both fittings down a bit.

zep Posted December 12, 2021 Author Share Posted December 12, 2021 The other option is thread the outside of the master cylinder inlets. There is definitely enough meat, just need to measure to see if it's a common thread size. Quote Link to comment Share on other sites More sharing options...
