    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 to five uses.
    Medium Locking Strength—Strong enough for most applications, these threadlockers hold firmly until you break their bond with a combination or ratchet wrench.
    Thin Liquid—Seep into tight spaces better than thick liquids, so they're best for fine threads.

    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.

    High-Temperature Threadlockers

    Prevent heat from loosening fasteners with threadlockers that resist temperatures up to 450° F. You only need a few drops to evenly coat threads. As you twist parts together, exposure to air is blocked and the threadlocker begins to harden.
    Primer (sold separately) cleans the surface and decreases the time to reach full strength. It is recommended when working with aluminum, stainless steel, and titanium; black-oxide finishes; and cadmium and zinc coatings.
    Medium Locking Strength—Strong enough for most applications, these threadlockers hold firmly until you break their bond with a combination or ratchet wrench.
    Thick Liquid—Fill larger gaps than thin liquids, so they're best for coarse or worn threads.

    Bottle

    Tube

    Even on oily surfaces, these retaining compounds keep their hold. Use them to fill gaps up to 0.015" to secure worn cylindrical metal parts such as shafts, bearings, and press-fit assemblies. These retaining compounds begin to harden once coated surfaces are pressed together, blocking exposure to air.
    Primer (sold separately) cleans the surface and decreases the time to reach full strength. It is recommended when working with aluminum, stainless steel, and titanium; black-oxide finishes, and cadmium and zinc coatings.
    Low Locking Strength—Compounds with low locking strength prevent threads from loosening due to vibration and can be adjusted without tools.
    High Locking Strength—Compounds with high locking strength require both heat and a hand tool to unthread.

    Tube

    Bottle

    Formulated for high lubricity, these sealants allow easy assembly of finely threaded hydraulic and compressed air system components. They're also free of fillers that could contaminate system media. These sealants are anaerobic, so they don’t begin to harden until coated surfaces are threaded together, blocking exposure to air.
    Medium Locking Strength—These sealants have medium locking strength, which prevents threads from loosening due to vibration and shock. They require a hand tool to unthread.

    Thread Sealants with PTFE

    Image of Product. Front orientation. Thread Sealants. Thread Sealants with PTFE, Tube.

    PTFE provides a slippery surface that keeps threads from binding. These sealants are anaerobic, so they don’t begin to harden until coated surfaces are threaded together, blocking exposure to air.
    Low Locking Strength—Sealants with low locking strength prevent threads from loosening due to vibration and can be adjusted without tools.

    Non-Hardening Thread Sealants

    Image of Product. Front orientation. Thread Sealants. Non-Hardening Thread Sealants, Tube.

    Tube

    Often used in high-vibration applications that could cause standard thread sealants to fail, these never fully harden and remain pliable enough to self-heal and stop leaks before they start. Formulated without PTFE, these sealants are less slippery and less likely to result in overtightenting than sealants that have PTFE, making them good for plastic pipe where overtightening could lead to cracks and breaks. They have low locking strength, so they can be adjusted without tools.
    Cannot Be Sold To—Sealants that cannot be sold to the listed regions are restricted due to local VOC (Volatile Organic Compounds) regulations.
