Does this stuff seal pneumatic (800 psi) threads on an and npt fittings.

I’ve not used it for your application however, her is the product discription for reference Formulated for metal, tapered ppe thread fittings. Protects threaded areas from rust and corrosion. Uses: head bolts, oil senders, oil and coolant lines, fuel fittings. Features & details Cures rapidly to withstand 10,000 PSI Perfect as a replacement for Vibra-Seal pre-coated parts Prevents galling and protects mated threaded areas from rust and corrosion

Can this be used on plastic pipe

Here is a copy and paste of the product description. "Formulated for metal, tapered ppe thread fittings. Protects threaded areas from rust and corrosion. Uses: head bolts, oil senders, oil and coolant lines, fuel fittings". Hope this helps.

What's the difference between this & Special Edition? I need 2 use it 2 seal inline fuel filter thread brass fitting 4 a motorcycle tank 2 carb.

I tried a number of things to seal a brass tee into a motorcycle oil pressure outlet. Nothing worked 'til I tried this stuff. Be sure to clean the threads well beforehand. If the stuff is rated for fuel, I'm sure it'll work for your application. It's good stuff.

What's the difference between this & Special Edition? I need 2 use it 2 seal inline fuel filter thread brass fitting 4 a motorcycle tank 2 carb.

The special edition is no doubt like many other products listed on Amazon a seller attempting to use the false label of a "special edition" to lure buyers to buy from them at a higher price, without prime shipping and more often than not slower shipping. I am willing to bet if you contact the maker of the product that they do not produce a "special edition".

Works great

Sorted my leaking head bolts in an Ls. Used arp but the chromolly bolts don’t come with sealer like all the stock and stock replacement bolts do. Put on 3/4 of thread and install. Perfect. Further used on head plugs. Sealed up also without leaks. The stuff is incredible for automotive.
