Is there any difference between the Permatex 56521 and the Loctite 565?

I seem to live in an area where the Permatex salesman is more persistent and successful than the Loctite man and thus, having trouble finding the Loctite 565.

I've found that FoMoCo regards the two as similar and a few other places on the web that regard the two as interchangeable.

From what I can tell, it seems to be the same stuff. I've used both. It's just a thread sealer.

I use Loctite 545. The bottle states it's for Hydraulic oil fittings, but when I asked the regional rep, he said there would be no problem with using it for my drain plug.

IMO, a new O'ring, on the drain bolt, makes thread sealer superfluous.
But it is called out in the service manual.

I use whatever generic teflon pipe thread sealer they sell at my local building supply store.

I think it mainly serves as a very low strength thread locker. An O-ring joint like these drain plugs barely has to be more than finger tight to be leak proof. Using the sealer probably makes a lightly tightened drain plug less likely to back out from vibration.

Teflon is not a glue or locking compound. It helps the scrambled eggs out of the skillet.

Like I said, pretty much the same thing as this:

It's like putting a really thick grease that won't wash off with oil or water on the threads to stop any leaks. I've never changed the o-ring or added any more teflon to the threads and I've never experienced a leak. A lubricated o-ring will last a long time if you don't over tighten it.

I have used neither tape or sealant for 21k miles. No leaks or issues. Go figure.

Perhaps the 'acrylic thread sealing adhesive' is to keep the plug from backing out
under all of that engine vibration, rather than to seal leaks.

Just a thought.

+1 to Johnboy's comment. An O-ring joint like this is leak-tight against over 100 PSIG with no sealant. The "sealant" mainly keeps the plug from backing out so you aren't tempted to torque the snot out of it, resulting in stripped threads in the swing arm (as quite a few XB owners have experienced).
