Exclamation thread sealant

Workshop manual says to use hylomar sealant on the fill and drain plugs of the transfer case and transmission. Can I use Permatex thread sealant w/PTFE? I can't find Hylomar anywhere by me. I don't want to order it online and wait. What does everybody use?

taken from RAVE Workshop manual maintenance section for the transfer case:

"9. Thoroughly clean filler/level plug threads prior to
applying fresh ’Hylomar’ sealant. Fit plug
Tighten to 30 Nm, 22 lbf ft."

Barry, You don't have any leaking? have you run the truck since?

Follow-up Post:

Funny thing, I just checked the owner's manual and it just says to clean and refit drain and fill plugs and doesn't mention the use of sealant.?.?.?.?.?.? So what gives? the owner's and manual the workshop manual will have to duke it out?

Follow-up Post:

what do I do ??

A lot of people (myself included) just use some pipe sealant on the threads. I always just take the plug to the wire wheel to clean the threads of the old stuff, then get the liquid pipe sealant, spread a little around the threads and reinstall. No leaks at all, and you should be able to find it at any hardware store near you.

Oddly mine leaks from every place that has sealant. The drain and fill have no sealant and don't leak. Go figure.

No need for it. I coat them in anti-sieze.

Since I use the FSM I've never heard of using any kind of sealant. I just seal mine with good hopes and well wishes and it doesn't leak... much.

Follow-up Post:

So the general consensus is no sealant. Maybe some anti seize if I', feeling generous.
sounds good.

Yeah, there isn't really a need to seal it. I never used to, now its kind of hit or miss. If I think of it, and there is some laying around in the shop, I'll do it. Otherwise, I just wipe the plug clean and reinstall.

Tapered pipe thread connection should not need sealant if in proper shape and tightened properly. It does help lubricate the thread when tightening, which is a good thing. Any pipe dope should be fine.
