As part of practicing my lathe skills I am going to turn some hose reducers (like these things from CBS: https://www.carbuilder.com/uk/black-nylon-stepped-reducer-joiner-1619mm-2522mm?gad_source=1&gclid=CjwKCAjwkuqvBhAQEiwA65XxQJozxN53oPFmuGTq0LBSXDr4 Js1xOiA2siQpLEvQz4Tw2OlHNL_2fxoCwkUQAvD_BwE).

I'm using them in the low pressure side of my braking system.

I have a sizeable stick of Delrin - so could turn them from that.

Can anyone point to whether Delrin is compatible with brake fluid, or not?

Worst case is I buy a length of brass, or steel and use that to make the reducers...

Not recommended apparently;

Perfect - thanks

Just to update incase others find this info later.
This info indicates compatibility : https://www.spacematdb.com/spacemat/manudatasheets/Delrin%20design%20info.pdf

And some Googling has reminded me that Voucht (on here) used Delrin for reducers in the way I intended to...


Nonetheless - I think I will use brass, given it's not very expensive and it's definitely already used in brake fittings...
