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.

Thread Sealants with PTFE


Applicator-Top Can	Tube

Cartridge	Bottle

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.

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.

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 Sealant Tape for Stainless Steel Threads

This tape is thicker to prevent seizing and galling associated with stainless steel threaded connections. It’s also good for use with other metals. This tape has a higher density than standard tape for a better seal between threads. Made of PTFE, it has a slippery surface that keeps threads from binding to make parts easy to assemble.

Thread Sealants for Oxygen Systems


Tube	Jar

Completely free of oil and chemically inert, these sealants are safe to use with wet and dry oxygen systems. They contain PTFE, which provides a slippery surface that keeps threads from binding. These sealants are non-hardening, 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.

Tube—The sealant in a tube is a good alternative to thread sealant tape—like tape, it forms PTFE strings between tightened threads, but excess material liquefies, so it won’t clog system components downstream.

Thread Sealant Tape

Made of PTFE, this tape has a slippery surface that keeps threads from binding to make parts easy to assemble.

ePTFE with Graphite—ePTFE tape with graphite creates a better seal between threads than plain PTFE tape, which helps prevent fluid and gas leaks. The graphite attaches to the PTFE, so this tape does not emit harmful VOCs.

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.

Certificates with a traceable lot number and product shelf life are available for these products. Download certificates from ORDER HISTORY after your order ships.
