    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.
    NSF/ANSI 61—To adhere to safety standards for drinking water systems, use sealants that meet NSF/ANSI 61.

    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.
    VOC-Free—VOC-free sealants won’t harm the environment and comply with LEED Green Building standards. VOC stands for volatile organic compound.

Since the sealant is anaerobic, it doesn’t begin to harden until coated surfaces are threaded together, blocking exposure to air. It has low locking strength, so it prevents threads from loosening due to vibration and can be adjusted without tools. It meets NSF/ANSI 61 for use with drinking water.

    Reusable Non-Hardening Thread Sealants for Coarse Threads

    Image of Product. Front orientation. Thread Sealants. Reusable Non-Hardening Thread Sealants for Coarse Threads.
    Much thicker than sealants for fine threads, these sealants bridge the gaps between coarse threads. Threads coated with these sealants can be installed multiple times without recoating. They have low locking strength, so they prevent threads from loosening due to vibration and can be adjusted without tools. They meet NSF/ANSI 61 for use with drinking water.

    Non-Hardening Thread Sealants

    Applicator-Top Can

    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.
    NSF/ANSI 61—To adhere to safety standards for drinking water systems, use sealants that meet NSF/ANSI 61.

    High-Temperature Thread Sealants

    Image of Product. Front orientation. Thread Sealants. High-Temperature Thread Sealants.
    These sealants have high locking strength, so they work in demanding applications, such as securing mounting studs in motor housings. They also withstand applications with large temperature swings.
    Room Temperature—Room-temperature cure sealants must be mixed with water for use; they harden as the water evaporates. Mix about five parts powdered-sealant to one part water to form a thick consistency similar to peanut butter. Hardening can be accelerated with heat; do not heat to above 200° F. They require a hand tool to unthread.
    1,000° F Maximum Temperature—1000° F max. temp. sealants expand as they harden.
    1,500° F Maximum Temperature—1500° F max. temp. sealants are for use on cement-lined pipe joints prior to welding. The heat from the welding torch helps them begin to harden.

    Drip-Free Non-Hardening Thread Sealants with PTFE

    Image of Product. Front orientation. Thread Sealants. Drip-Free Non-Hardening Thread Sealants with PTFE.
    Apply these thread sealant sticks without a mess. They contain PTFE, which 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. They meet NSF/ANSI 61 for use with drinking water.

    Thread Sealants

    These thread sealants are anaerobic, so they don’t begin to harden until coated surfaces are threaded together, blocking exposure to air.
    Medium Locking Strength—Sealants with medium locking strength prevent threads from loosening due to vibration and shock. They require a hand tool to unthread.
    NSF/ANSI 61—To adhere to safety standards for drinking water systems, use sealants that meet NSF/ANSI 61.
