Technical Data Sheet
Vibra-Tite® 442
Product Description
Vibra-Tite 442 High Pressure Thread Sealant is a fast
curing high strength anaerobic sealant which seals
hydraulic and pneumatic fittings, resisting high
pressures and vibrational loosening. This thixotropic
behavior of 442 makes it well-suited for use on large
diameter pipes. This product has excellent solvent
resistance and withstands temperatures to 300 ºF.
Typical Applications
Typical applications are hydraulic and pneumatic
fittings, servomechanisms and fine filtration systems,
especially when using large diameter pipes or
fittings.
Instructions for Use
Ensure parts are clean, dry and free from oil and
grease.
Procedure for Application

directly onto threaded parts.
Compatible Primers
Primers such as Vibra-Tite Excel 611 (Primer N) or
Vibra-Tite Excel 612 (Primer T) can be used. The use
of primers can cause loss of strength and
performance should be tested.
