Applicator-Top Can | Can |

Tube | Applicator-Top Bottle |
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.
Cannot Be Sold To—Sealants that cannot be sold to the listed regions are restricted due to local VOC (Volatile Organic Compounds) regulations.

Non-Hardening Thread Sealants with PTFE
| |
Applicator-Top Can | Tube |
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—Gasoila sealants are designed specifically to resist gasoline and fuel oils, making them best for motors, nozzles, pump assemblies, and fuel lines.
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.
Cannot Be Sold To—VOC regulations restrict sales of sealants that cannot be sold to the listed jurisdictions/areas.

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.

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.

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.
