    Thread Sealant Tape

    Image of Product. Front orientation. Thread Sealants. Thread Sealant Tape.
    Made of PTFE, this tape has a slippery surface that keeps threads from binding to make parts easy to assemble.
    ePTFE with Graphite—ePTFE tape with graphite creates a better seal between threads than plain PTFE tape, which helps prevent fluid and gas leaks. The graphite attaches to the PTFE, so this tape does not emit harmful VOCs.

    Tape Threadlockers

    Image of Product. Front orientation. Threadlockers. Tape Threadlockers, Roll.

    Roll

    The easiest threadlocker to apply, this tape wraps around fasteners with no mess. Keep a roll in your toolbox—no worrying about leaks or it drying out. Unlike most threadlockers, these don't need to be applied every time you remove and reinstall your fasteners. Put on a fresh layer once every three uses. This tape is ready for immediate use. There is no drying or cure time required.
    Medium Locking Strength—Strong enough for most applications, these threadlockers hold firmly until you break their bond with a combination or ratchet wrench.
