    Applicator-Top Can

    PTFE provides a slippery surface that keeps threads from binding. These sealants never fully harden, remaining pliable enough to self-heal and stop leaks before they start, so they’re often used in high-vibration applications that could cause standard thread sealants to fail. Since they have low locking strength, these sealants can be adjusted without tools.
    NSF/ANSI 61—Sealants that meet NSF/ANSI 61 adhere to safety standards for drinking water systems.
