About Sealants

Select a sealant that can stretch, contract, and expand enough for your joints.

Thread Sealants with PTFE

Tube

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.

Medium Locking Strength—Sealants with medium locking strength prevent threads from loosening due to vibration and shock. They require a hand tool to unthread.
