Note: Some fasteners have a dry thread
locking compound pre-applied (Patch-Loc)
so no additional thread locking compound is
necessary when installing a “new” fastener.
These fasteners are designed to be
removed and re-installed only once before
applying additional thread locking
compound is necessary.
Retaining Compound
An adhesive used to secure bearings,
bushings, and cylindrical parts into
housings, or onto shafts. When cured,
bearing sleeve retaining compound fills the
gap between mating parts with a hard resin
that increases load distribution and protects
against corrosion. Follow the manufacturer
recommendations for use.
Adhesive
Used to secure a variety of components
immediately prior to assembly. May be
recommended for installing new
components or when reusing a component
that had a pre-applied adhesive. Follow the
manufacturer recommendations for use.
Thread Sealant
Used to seal threaded fittings and sensors
from air, fuel and oil pressure leaks and
prevent galling and seizure between
threaded parts. A thread sealant in paste
form is preferred over sealant tape. The
sealant should remain semi-pliable to allow
for component removal with standard tools.
Some thread sealants may require the use
of a cleaner or primer prior to use. Follow
the manufacturer recommendations for use.
Gasket Compound
Used to create a seal between mating parts.
Gasket compounds may be used with or
without the presence of a pre-formed
gasket. Gasket compounds may be solvent,
or silicone based, and cure when exposed
to air or designed to cure in an air-less
environment (anaerobic). Most gasket
compounds are designed to be applied to
clean surfaces free of oil, chemical residue
and previously used gaskets or gasket
compounds. Follow the manufacturer
recommendations for use.
