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.

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 regulations restrict sales of sealants that cannot be sold to the listed jurisdictions/areas.

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.

Sealants that cannot be sold to the listed regions are restricted due to local VOC (Volatile Organic Compounds) regulations.
