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 medium locking strength prevent threads from loosening due to vibration and shock. They require a hand tool to unthread.
