The greatest thing to me about it (despite the fact it works) is that one can does everything on every material you could usually imagine except ABS and I quote.
"galvanized steel, iron, brass, copper, aluminum, stainless steel, polyethylene, reinforced fiberglass, and PVC"
and then works with any gas or liquid you could pretty much want.
"Acids, Dilute, Gasohol (unleaded Gasoline and 10% Alcohol), Natural Gas, Air Compressed, Heating oils, Nitrogen Gaseous,
Ammonia Gaseous, Liquid Helium, Gaseous Petroleum Solvents, Aliphatic Solvents, Hydraulic Oils, Soap, Caustic Dilute,
Hydrogen Gaseous, Steam, Cutting Oils, (Low Aromatic), Inert Gases, Vegetable Oils, Diesel Fuel, Oil, Kerosene, Water
(Hot or Cold), Freons, Liquified Petroleum Gases (Butane, Propane, Mixtures), Gasoline (Leaded Unleaded) Mineral oils"
They state not recomended on Oxygen, but that per them (I asked once) is that they don't certify it as OK for breathing use and they figure that is the primary application of O2, not that it won't work with it.
So the one little can will do you around the house or shop forever. I think the little tube (which I bought to replace the can as I figured it more convenient) was about $3 at Home Depot. Anyway never again to worry if you have the right thread sealant for the right material for the right application, it is going to work. It is far better in fact IMHO than their T+2 sealant, though you can use that on ABS (and I do as here in AK our DWV is still ABS.) Although they say you can put it in service immediately for less than 100psi on less than 2" fittings and I do, I will mention that giving it a day or two to sit for any application does give you a better initial set if you are trying to solve a leaky fitting that you can't get to stop seeping. I have even used the stuff on straight threaded hydraulics fittings which were O-ring sealed where the O-ring land was boogered up, without the O-ring, let it set for 2-3 days then put it in lowish
(1500psi) service without issue.
Plain good stuff, when I was an engineer every commercial hyraulic system I ever used had #5 on it, though at the time I didn't realize it.
OK I've gone on about this stuff a bit much I guess...

When I worked as a natural gas pipeline grunt, Rectorseal(pretty sure
it was #5) was all we ever used to seal the service pipe threads into
the outside meter. I used to think that stuff was expensive, but
ounce for ounce compared to Loctite, it is a great bargain. Like
Permatex antisieze, one can will last a lifetime for most of us.....
