If all sealants are created equal, then why do experienced mechanics have preferences? I mean if repair manuals don’t mention which sealants you should use on gaskets, either is fine, right? Wrong. Loctite clearly owns a larger share of the thread locker market. In reality, both sealants have a lot in common and its even hard telling them apart.

permatex vs loctitec: Are thread lockers and thread sealants the same?

To beginners, they’re the same but they serve different roles. Thread lockers are adhesives applied to bolts and screws to keep them in place. In addition to stop them from vibrating and getting lose, thread lockers help coat screws and bolts stopping them from corrosion and rust. They come in varying colors with dark colored thread lockers being stronger and tougher to remove. Thread sealants on the other hands seal up any space between connectors making them air tight. In water pipes, they render gaps water proof. As you can see, they serve different purposes and each has its role.
