It’s probably no surprise to you that gaskets come in all different shapes, sizes, and construction—from copper header gaskets to rubber O-rings to the trusty old cork gasket for your diff cover.

But make sure to include liquid gasket makers in that mix too. Whether we’re talking RTV silicone or a specialty anaerobic compound, liquid gasket makers can come in really, really handy when you’re gasketing between two rough or uneven surfaces. In those applications, a typical compression gasket may not create the leak-proof seal you need.

To give you a closer look at some popular liquid gasket maker types (and why they’re so beneficial), Loctite made this handy video. It’ll dive into some of the chemistry behind these gasket makers, and show you a few popular applications.

Even if you’re familiar with this gasketing method, it’s still worth a watch because there may be some new compounds you haven’t seen before. It’s less than four minutes long, so check it out:
