Clutch Master cylinder question with new Ring Bros Reservoir

[MarkM66]

As long as it doesn't leak, it's fine, the fluid isn't under any type of pressure there.

any thread sealent, i prefer rector seal, or napa has a liquid teflon sealant as well, i would put some on the nipple threads, install, clean excess, then just clamp rubber hose on, as mark said there is no pressure there.
