Thread Sealant

[Shovelrick]

I'm back with thread sealant leaks lol, I recently found out about Gasoila from a gas station repairman so I ordered some for a problem leak I had and didn't realize I had a Non NPT fitting in the pressure regulator, didn't even know they made a fitting with AN on 1 side and Non NPT on other, so now other leaks are springing where I used Red High Tack, I pulled 1 fitting apart and the Red stuff looks like bubble gum that was in the sun, kind that gets stuck to your shoe and is a pita to get off but dont seal worth a darn, I need to figure out how to post a pic but Never try to use red High Tack for fuel fittings

Try the tape Rick, I swear it works great.

I already have the Gasoila (Who comes up with these names? LOL) and so far it's been working very good but I am picking some Gasoline rated tape too

They were probably drinking or smoking dope and it sounded good at the time.

Hey Rick,

Do I need that stuff on the flared fittings for the lines to my 780 Holley on my L78 build? Something else to remember when I have my builder assemble the engine I suppose.

Thanks,

John

Flared end fittings shouldn't have anything on them, the way I see it as long as the flare is done properly it'll seat in the mating surface without any sealant that could cause a leak, I do use a sealant name of Nylog Blue on Mini Split (Ductless) A/C unit fittings but it's designed for it and made from refrigerant, gas, brake or trans lines I wouldn't use anything

If I have a fuel leak I use the Permatex sticky thread sealer, been using it since the 90's when GM sold it under the Mr. Goodwrench brand.

Do you use it on flared end fittings?

Do you use it on flared end fittings?

Yes, I have used it on fuel and other fluid fittings, mostly head bolts though.

I used SS brake lines when I replaced all the lines on my 68 and what a PITA getting the flares to seal, I kept seating, loosen then reseat, It would have been great using something on those
