Default Loctite 242 as thread sealant

Loctite 242 is a standard solution to seal fasteners that thread into through holes with liquid, such as oil or coolant, on the other side. Seems like it should work just as well or better for pipe threads. I have a barb fitting going into the cooling system I'm going to use it on, and I think I'll also use it on the oil drain fitting in the pan.

Loctite 242 Technical Data Sheet

It maintains 100 percent of its strength after 1000 hours in motor oil at 257 degrees F, and most of its strength after time with coolant - certainly enough to hold back 15 psi.

Should look a lot neater than pipe tape or the JB Weld booger smears a lot of people do.

Hmm, do they have this at parts stores? I'd hit it.

242 is regular Red Loctite. And I like teflon pipe dope wherever possible. It absolutely never fails that 2 weeks after I put red Loctite on something I need to take it off. In fact, I don't use red even when the the manufacturer recommends it, sometimes. My ex says I have commitment issues, though, so take this all with a grain, lol.

I brought it up again with the guy who told me what he was doing over the weekend with Loctite 242. He corrected himself, said he actually meant Loctite 272. Harder to find, better to use for sealing. The pipe thread sealer is also good, but without the locking.

The red loctite 272, is designed for parts that are not going to be taken apart. You would have to take a torch to it if you decide to loosen any parts put together with 272. I would just use teflon tape.

Pipe tape looks great if you do it carefully and not like a Home Depot weekend plumber. Wrap clockwide and hold the tape close and taut, wrap 4 times or so and wrap the threads with your fingers to work the PTFE tape into the threads after cut, looks great and works well.

Either that, or I use Loctite 567 thread sealant stick. Same idea without the tape. I wouldn't use one of their locking chemicals as a sealant ever.
