anaerobic pipe dope

PERMATEX

in over 44 years in the trade and installing millions of running feet of brass and every other type of pipe imaginable i have never, ever heard of a compound you could not use on brass pipe threads. some compounds are better for some specific applications although . refer to suggested manufacturers specifications. you did come to the correct place. now to further your inquiry check with the pertinent vendors ie: hercules , permatex , utility , s.o.s. whitlan , laco , rectorseal , solderseal , radiator specialty , gasoilia , alumac , expando , i may have missed a few but these are my favorites and should get you started. let me know if you want more. my personal favorite is PERMATEX. FOR REAL MEN.

I have a tube of pipe dope made by a chicago co. called Anti-seize Technology it is a anerobic pipe sealant with teflon. I have used a dope made by Cajon called Swak that is anerobic. Loctite makes a dope called PST that is anerobic with teflon and is formulated for stainless steel. I have used all of them on brass with no problems. The only pipe materials that I have heard of that they are not compatible with are plastic pipe other than pure teflon. If you contact the mfg. they will advise on compatibility. bob

Bob is correct, Scott

The term "dope" is of early airplane origin, indirectly.

The original slang term "dope" alluded to inside information as in, "hey, what's the dope on that stock?".

It enforced the notion of secret principles which would make something out of nothing.

Early airplanes had low HP engines hence had to be light weight. Wings and fuselages were made of spruce covered in linen canvas. To make the linen airtight and moisture resistant so it would not wrinkle and defeat the airfoil effect, they used nitrocellulose (lacquer essentially).

When brushed on the canvas it became tight as a drum and had imparted upon it properties previously unknown. Hence the term "dope".
