Thread sealant

[4Kings]

Not sure where I need to post this so mods move it if necessary...

I read somewhere on here about a thread sealant that was used to seal a bolt on a transfer case. I changed the fluid in my transfer case a few weeks ago and am noticing a small drip from the bolt. I seem to remember it was a special application sealer but I can't find the thread.

I have sucessfully used several thread liquid thread sealers hundresds of times. I like the Permetex pipe joint compound 80045 it is more like a heavy shellac type gasket sealer. This type I like much better than the Teflon liquids/pastes. Teflon tape is obsolete.

I too rely on Permatex but, pick the version to fit a particular application. My Auto Parts store has small tubes, each labeled for an intended use. If I had to pick one Permatex for most engine/transmission jobs, I'd use the Non-hardening type.

I keep a tube of Permatex #2 non hardening sealant in my workshop as a universal sealant for any non critical applications. While the name implies its a gasket sealer only, read on the label that it is also good for threaded connections. It has the exact same ingredients as the pipe compound above, but in slightly different %....I think it is a tad thicker than the pipe compound.

Unlike the rest of the permatex pipe sealers( http://www.permatex.com/products/Automotive/thread_compounds/a_thread_sealants.htm ), the pipe compound (and I assume the near identical#2) states that the threads can have a "light film" of oil on them. Anyway, it works for me. Maybe call the company to confirm my suspicions of these products being almost identical.

Teflon tape is not obsolete, you just don't want to use it on any application where a piece of tape might come off and get stuck in some orifice and restrict oil flow.

I believe the tape is definately obsolete for plumbing if all types thread sealing of any sort.

It quit fumbling around with it a couple of decades ago.

You are correct I have seen that done in most spectacular fashion.

Liquids & pastes if hastily used will contaninate systems & restrict or plug orfices as well.

Permatex #2 is a softer setting sealant. #1 sets hard - avoid it.

Many hardware store brush on teflon sealants are great. They take high heat, and are gas and oil resistant.

Like mentioned, use care not to get any inside the device you are sealing.

Permatex offers several "thread sealers" that are made for different applications. Their #2 will probably get the job done, but if it were mine I would go for the thread specific product.
