About Sealant Flexibility

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

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.
Sealants that meet NSF/ANSI 61 adhere to safety standards for drinking water systems.

Thread Sealants
These thread 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.

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.
