Three Bond High Performance/Adhesion Liquid Gasket TB1207B

I have used this product to seal motorcycle engine side casings, valve cover gaskets, engine jets, and gasoline generator engine parts. The seal has been perfect every time. I am very careful about cleaning the gasket surfaces entirely and then cleaning them with rubbing alcohol to ensure spotless mating surfaces, and if you do the same, the Threebond 1207B won't disappoint. It feels stickier/tackier than any auto store RTV sealant I've ever used, and thus you don't need as much to make a 100% effective seal. This does make it quite messy to use, so use gloves and use the product sparingly. It is all I will ever use ever again.

This is a great product, it applies easily, and seals perfectly every time. As a shop owner it's invaluable to have something like this that you can rely on. I know when a customers car leaves the shop that it won't be back for leaks. Just apply and let set up overnight, oil pans, timing covers, transmission pans, differential covers, etc.

This is the same product I used for years as a Suzuki mechanic. It is sold at dealerships for about $25 as Suzuki1207B This is a fantastic product for sealing case halves and sidecovers on engines. It works easily as well as Yamabond or Hondabond without being all stringy (you know what I mean if you have used them😂 This is easy to use, and remove when rebuild time comes.

This has a limited shelf life. It is also not thick-bodied like the bubble pack stuff you see at auto parts stores. You don't need very much, and it sets up quickly. All of this is good. It is too easy to overuse the thick bodied RTV. Overusing RTV increases squeeze-out, and that is BAD. The squeezed-out blobs if they fall off, especially the tiny ones, can get into the little passages of engines and transmissions. If that happens, things can get clogged up with really bad out comes. Three-Bond can't cause excessive squeeze-out. It can't cause much squeeze-out at all. Three-Bond is just gooey enough to do the job of adhering, and no more. Definitely read and follow the torque specs for whatever you are working on!

The product came exactly as described in an intact, sealed tube. It is a very effective liquid gasket, I highly recommend it especially for high vibration motor sports. Moreover, the nozzle that it comes with has a large variety of different diameters for the perfect application.y The only reason I deducted a star is because the expiration date is only a few months out. Unless you’re rebuilding multiple engines in a few month period it will definitely expire before you can use it all. I am rectifying this by storing it in airtight plastic wrap in the refrigerator. It will probably still be useable after the date, but it would be nice if one of the most expensive gasket makers on the market came with a later expiration date.

Works great! But wear gloves, stuff doesn’t come off for anything. Makes normal greasy hands look like a walk in the park. I got this ask over my hands and it took an hour of scrubbing and every kind of soap I had in house until I arrived at nail polish remover and that barely worked. lol

I used this is place a new camshaft seal in my Honda B18B1 engine, as pictured. I put the cam cap bolts back on finger tight, then 15 minutes later I tightened the 4 bolts on it. I start the car's engine 45 minutes later and drive for 10 minutes. The next day, I didn't notice any oil go past the RTV gasket. Unlike Hondabond (with 2 different packages), the Threebond package didn't rip open on the bottom, on the first time of use. Update: After 2 years of usage, and using half the package, the package has yet to tear; though keep in mind I've folded the bottom half of the package up and into itself.

1207B s great sealer, been using it for years. Tube i received was out of date in less than a month from the time I received it. Returned it .
