About Sealant Flexibility

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.
Gasoila sealants are designed specifically to resist gasoline and fuel oils, making them best for motors, nozzles, pump assemblies, and fuel lines.
Sealants that meet NSF/ANSI 61 adhere to safety standards for drinking water systems.
VOC-free sealants won’t harm the environment and comply with LEED Green Building standards. VOC stands for volatile organic compound.
VOC regulations restrict sales of sealants that cannot be sold to the listed jurisdictions/areas.

Non-Hardening Thread Sealants
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.
To adhere to safety standards for drinking water systems, use sealants that meet NSF/ANSI 61.
Sealants that cannot be sold to the listed regions are restricted due to local VOC (Volatile Organic Compounds) regulations.

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.
Reusable Non-Hardening Thread Sealants for Fine Threads
Formulated to flow into small spaces, use these sealants between fine 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.
Drip-Free Non-Hardening Thread Sealants
Apply this thread sealant stick without a mess. Often used in high-vibration applications that could cause standard thread sealants to fail, this sealant never fully hardens and remains pliable enough to self-heal and stop leaks before they start. It has low locking strength, so it can be adjusted without tools.

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.
Heat cure sealant requires heat of at least 212° F to harden. Above 300° F, the sealant hardens in about 15 minutes. For temperatures below 300° F, it may take up to 4 hours to harden. It requires both heat and a hand tool to unthread.
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.
Sealants that cannot be sold to the listed regions are restricted due to VOC (Volatile Organic Compounds) regulations.
