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: Works great - This anti seize is good stuff.

Best pipe sealant we have used. It’s thick, stays pliable and we have very little leaks even without teflon tape. This is the only sealant we use.
