Threadlockers
Prevent threaded fasteners from loosening due to shock and vibration. These threadlockers begin to harden once coated surfaces are threaded together and exposure to air is blocked. Primer (sold separately) cleans the surface and decreases the time to reach full strength. It is recommended when working with aluminum, stainless steel, and titanium; black-oxide finishes; and cadmium and zinc coatings.
Threadlockers with medium locking strength require a hand tool to unthread.
Threadlockers with high locking strength require both heat and a hand tool to unthread.
088 has a thin consistency to flow into fine threads.

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.
Sealants with medium locking strength prevent threads from loosening due to vibration and shock. They require a hand tool to unthread.
To adhere to safety standards for drinking water systems, use sealants that meet NSF/ANSI 61.
