Don't use teflon on SS - Page 2

post #11 of 30
so what science magazine did you get that experiment out of?

lol

teflon tape is made of Fail.

Any poly/metal connection with teflon tape will fail over time. this I know from experience.

Teflon is inert...

Oxygen is what makes metals (get the root now) oxidize.

Without oxygen there will be no rust...lol also known as oxidation


I would not reccomend teflon tape for poly/brass connections at all.

for stainless/brass connections the teflon will make a slight barrier to prevent electrolysis

When you say SS first of all there are many many grades of SS--some are even magnetic..

Secondly teflon is the ingredient in most antisieze compounds used to protect dissimilar material from reacting. This again is from personal experience refitting yachts. If you put a SS fastener in a deckfitting that is not stainless you will have corrosion and elctrolysis within hours depending on conditions...

The only parts you got right were that celery is edible...and SS rusts...

I think you just drew the wrong conclusions from a DIY science magazine or web site.

^_ ^ been there done that!

from the second article, "rouging" sounds like more of a culprit than Teflon tape.
Rouging only occurs in pure water thats why i said salt water.
What is the scenario in which your leatherman would be susept to rust but isn't?
I'm just as surprised by this as others. My boss just showed me this happening last week on a part we bought for our machine.
He understands it fully but he also has about a hundred patents to his name and is a prodigal genius.

1. what do you think your running in your liquid cooling system? distilled water is pure water.

2. I accidentally deleted a sentence, I vacuum packed my (stainless steel) leatherman and it didn't rust.

This is one of the most pointless threads I've seen, and I've seen a lot of them....Teflon tape does not cause stainless steel to rust....

the examples i have seen have been with desalinized water and waste water.
If your cooling loop uses pure water then it is susept to both rouging and rusting.
When you sealed your leatherman did it have water inside? The scenario i am using has water in contact with a steel surface that is bound air tight.
And thank you cyberdruid for pointing out that all steels rust and that there are different kinds of steel.
All I'm saying is that teflon tape sealing off part of a steel fixture can encourage rust faster. It is not an oxygen free enviornment. The oxygen has to be pulled from somewhere else.

I agree--when I have taken apart all statinless fittings I have seem discoloration , blackening from any nickel, but never anything I would call "rust" like the way carbon steel rusts.

The oxygen is coming from the water drting out I imagine.

the fact that it is sealed ...well it just does not make sense or correalate to my experience. Sealing something that is wet with rubber or whatever is not going to be any rustier than is the same amterial is left in water unsealed...my guess.


Not all stainless steel is composed of the same elements...there are many amny stainless formulas..they all have different reactivities to different elements...

The only thing I could think of is that the tape or rubber band or whatever is only giving the appearance of accelerating the process since it may prevent any of the iron oxide from washing away. This would actually cause the rusting to slow down since rust will actually provide a protective barrier.

Okay I want to modify my last statement.

If there is percolation..i.e. the water becomes vapor then recondenses then becomes a vapor again and so on due to temperature changes I could see that the water vapor being trapped under a film may very well cause a reaction.

The rubber band under water is not this reaction.

The rubber band may have some impurities that accelerate oxidation though.

So I would say pretty much assuredly do not use rubber bands to seal stainless steel fittings...they will rust and leak
