sealing hydraulic connections

Hydraulic connections (e.g. clutch, brakes) are self-sealing, right? No
compound for fear of contaminating the hydraulic fluid, and no
anti-seize for the same reason?

 

I wouldn't have a problem with antisieze, as long as you keep it on the
threads, and off the sealing surfaces.

No sealant or anti-seize at all.

Get the flares right and it will seal just fine dry. You do have to tighten
it enough, though. *That* is very important.

 

Okeedok. I'd feel better skipping gunk on these connections, as I'd
rather not risk screwing up and contaminating the fluid.

Thanks to you both.

Incidentally, I got my parts today and the clutch slave cylinder
actuator rod is in fact pre-lubed inside the boot, so it looks like I
don't need to buy another $6 worth of grease...

 

I learned the reason for using some sort of sealant the other day when
attempting to use my MityVac pump to "flush" the fluid/bleed the brakes.
Too much air came through the threads for it to work properly. Something
thick on those threads should do the trick.

 

Teflon tape on the threads of the bleeder screw is a popular solution.
Put it on the threads only.

 

Gives me a good reason to pick some up. Every once in a while I find
myself doing some plumbing and don't have a roll handy... Thanks.

 

Teflon plumbing tape.

 

i went ahead and used teflon tape last time i did mine. kept it on the
threads, and not too close to the end. pipe dope would likely work well
too. or anti-sieze, possibly.

 

thanks, guys. that's what i'll use.
