Product Description

Vibra-Tite 121 i s a medium strength, a naerobic thread l ocking compound. Vibra-Tite 1 21 is designed f or l ocking t hreaded f asteners t hat r equire disassembly with standard hand t ools. T he pr oduct performs on a luminum, s teel, pl ated pa rts, s tainless steel, and special alloy parts. Vibra-Tite 121 exhibits good temperature and is solvent resistant.

Typical Applications

Vibra-Tite 1 21 will lo ck a nd s eal f asteners, a nd s et screws. Vibra-Tite 121 is used in applications where shock and vibration may cause the fastener to loosen.
