Review: OIL COOLER BRASS TO ALUMINUM FITTINGS. NO LEAKS NOW. - Generally, used on high pressure natural gas metal lines ( black pipe ). Used orange sealant. Used blue sealant, used black sealant, used thread tape, at 50 PSI on remote external oil cooler for air cooled 2332cc engine would leak at fittings. To create more space between high torque starter, and cooler, down sized from 72 plate to 48 plate cooler. Brand new cooler, same with brass fittings. 12 yrs with 72 plate, no leaks. Friend suggested using Hercules Real Tuff sealant. Read up. Liked what I read. Brush in can/bottle is stiff as an oid straw broom. Worthless. This stuff is thicker than cake frosting. A little bit, goes a long way. After using Brake Kleen and dry cloth to clean fittings, Used nitrile glove on hand, to dab a bit of sealant on male fitting. Using flare wrenches, tightened things up. Wiped excess sealant away. Took car for ride ... No leaks ... not a micro drop of oil. This stuff gets everywhere ! I used hand/body lotion mixed with liquid hand wash dish soap. The lotion makes a difference. Still have to work at picking and scrapping off skin and clothes. Product does what it promises to do.
Review: The only pipe dope I'll ever use again - This stuff is profoundly, utterly, in a different league than any of the Rector or Oatey dopes I've used in the past. Easy to apply, lubes and seals _flawlessly_ - including out of spec threads that stubbornly refuse to stop leaking no matter what other dopes I've tried. No cure time. Works on gases (I'm using for propane and air lines) and water (I'm using for that too), down to absurdly low temps you won't see outdoors on this planet (and I need it, it gets into the -50° range here). Flawlessly seals brass to polymer connections - or metal to metal, or poly to poly. It stays pliable, so you can unthread it, clean it up, and refit as needed, if you want to swap pipe around. It's thick and goes on easy, doesn't drip, but it will hitch a ride on your hands and tools - so have a rag handy. This stuff is incredible. Top performer! As long as they keep making this, I can't see myself ever using a different pipe dope for my needs. I'm completely sold on it.

### ⭐⭐⭐⭐⭐ Reliable, Heavy-Duty Thread Sealant That Gets the Job Done
*by N***O on April 23, 2026*

This PTFE thread sealant has been an excellent product to keep on hand for plumbing, shop, and general repair work. What I like most is how versatile it is. It works well on all kinds of materials, including metals, PVC, CPVC, and ABS plastics, so I don’t have to keep switching between different products depending on the job. It spreads smoothly, fills gaps and imperfections effectively, and helps create a solid, dependable seal without a lot of extra effort. One of the biggest advantages is how quickly it performs. Once applied, it forms leak-free joints that can be used immediately, which is a huge time saver when you’re trying to finish a repair or installation without waiting around. I also appreciate that it’s suitable for lines carrying air, liquids, drinking water, and gas, which makes it a very practical all-purpose sealant for both home and professional use. The performance specs are impressive too. It handles a wide temperature range and stands up to high pressure, so it gives real confidence that the seal will hold under demanding conditions. Overall, this is a dependable, heavy-duty sealant that performs exactly as promised. If you need a strong, multi-purpose thread sealant you can trust, this one is definitely worth buying.
