About Sealant Flexibility

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.

Sealants with low locking strength prevent threads from loosening due to vibration and can be adjusted without tools.

Sealants with medium locking strength prevent threads from loosening due to vibration and shock. They require a hand tool to unthread.

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

Drip-Free Thread Sealants with PTFE

Apply this thread sealant stick without a mess. It contains PTFE, which provides a slippery surface that keeps threads from binding. 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.

Non-Hardening Thread Sealants with PTFE

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.

VOC (volatile organic compounds) regulations restrict sales of sealants that cannot be sold to the listed jurisdictions/areas.

Thread Sealants for Hydraulic and Compressed Air Systems

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. Sealants with medium locking strength prevent threads from loosening due to vibration and shock. They require a hand tool to unthread.

Sealants with high locking strength work in demanding applications, such as securing mounting studs in motor housings. They require both heat and a hand tool to unthread.

Thread Sealants for Refrigeration Systems

For use in refrigeration systems and applications exposed to strong chemicals, these sealants have excellent solvent resistance. They’re anaerobic, so they don’t begin to harden until coated surfaces are threaded together, blocking exposure to air. Sealants have medium locking strength, which prevents threads from loosening due to vibration and shock. They require a hand tool to unthread.
