Im doing some black iron pipeing and was wondering if I should use teflon tape first and then apply the black Permatex Pipe Compoud?

white pine said:A couple questions on the loctite 55 pipe sealing cord.
1. Is it compatible with Rectorseal 5, or should a teflon pipe dope be used?
2. Do you guys file the threads in a few places to keep the cord on the pipe?
I just bought loctite 55 and will start working on the fittings for my tank this week.
Thanks

One more question. I had a few pipes cut and threaded. How well if at all does the oil they use when cutting the threads need to be cleaned before joining fittings?
Thanks in advance.

Is there a sealant or grease that can help insure that the spherical mating surfaces on a threaded union don't leak. The various pipe thread sealants I have all have fibers in them and that doesn't sound like it would help. Might silicone grease be something to smear on lightly?

Faucet stem lube works great on the mating surfaces and on the large union thread. It's mainly a lubricant that you need.
Chap Stick works well also, and it comes in convenient size dispensers for one time or small jobs

We use the locTite thread cord and a little dab of whatever thread compound we have along. The cord is the real deal. I had learned about using hemp for thread sealing via a couple of German boiler companies and it was the ONLY thing that would seal up the straight cut Euro style threads on some of that equipment.
I avoid teflon tape like the plague for the same reasons Hot Rod described.
