Is there harm in using Teflon GOLD tape on Brake Bleeder Valves?
I have some Gold/Mustard Yellow, Teflon type plumbers tape for GAS pipes, I was wondering if I place this on the upper portion of the bleeder valves would it be okay or will it disintegrate in the caliper due to the harsh fluid?
Besides grease, bees wax, would this be acceptable?

Teflon tape should be fine. Just one or two wraps should do it. Once the bleed valves are closed no fluid can get to it anyway.
(you'd probably have to replace it every time) What about small O rings to seal the bleed valve thread against the calliper body? I've been thinking about the same thing because I use a vacuum bleeder on my cars.

Are you looking for it to not seize? I can't see a reason how it could hurt. I have never used any form or lube/tape on the threads but I am all ears.

I noticed when using my new Reverse Bleeder when I opened the valve it would leak out the side threaded area.
I tried this on my son's 190E and it worked but he was the guinee pig but my baby 911 is a princess so I need to make sure it will not introduce contaminants into the system

Why? to stop potential air/fluid leak when I bleed.

Jim, I know exactly what you mean about leakage at the threads when loosening the nipple. I've never seen or heard of anyone using teflon tape to stop the leaking....but that doesn't mean that it couldn't be done.
I would be careful of 2 things. One, that any excess tape doesn't cover the inner hole, and two, to be extra careful to not cross-thread during installation. In the past when I've purchased high quality bleeder nipples, I've noticed that they are sold with a small blotch of red gumlike compound. I'd be more inclined to research what the stuff is and how to purchase it. Just my .02 cents, brother.

Jim, I would be concerned how the tape would hold up at heat...other than that?
So this reverse bleeding is interesting but I like my power bleeder just fine v what is the selling point of the reveres job Ed

Hey Ed, I agree the temps would be an issue, Hmmm???
MS, As far as depth of the tape my intent is not go into the cailper but just on the upper portion of the thread leaving the relief hole un-tampered. Red Gummy Goo, probably sometime of high temp sealant, resistant to solvents.

As per speed bleeder's website: Speed Bleeder Features
The pre-applied thread sealant also displaces air and moisture during thread engagement preventing rust...which usually results in rounded off corners on the hex or busted off bleeder screws making it necessary to replace the caliper or brake cylinder. The application of thread sealant thus makes it easy to loosen or remove the bleeder screw at any time

Just make sure you don't use RED LOCTITE .... remember thats heat to remove ...
You can get blue loctite tape that may work well ?? Steve |

Personaly I would not use anything. Tightening and loosening a fitting with tape, some residue will get into the caliper.

my vacume brake bleader came with wax to put around the threads to prevent the air issue. teflon tape seems like it would work as well.
Why....because it is hard to tell if there is air in the system when air is getting into your vacume tube. You cant tell if it is from the brake system or simpley from around the threads. Chris 73 911 e |

experienced as SCCA Formula Ford crew....we used teflon tape...worked well when replaced once or twice per season. The red sealant looks like a good deal as well
