Gasket Maker is a single component,
room temperature vulcanizing gasketing compound designed
to provide reliable “formed-in-place” gaskets for mechanical
assemblies. This material cures on exposure to moisture in the
air to form a tough, flexible, silicone rubber gasket. The
product resists aging, weathering and thermal cycling without
hardening, shrinking or cracking. Designed to perform under
the higher load conditions of engines with closely spaced bolt
patterns (typically non-US designed), and maintains
outstanding oil, water-glycol resistance. OEM Specified.
PRODUCT BENEFITS
• High load resistance
• Improved oil resistance
• Sensor safe, non-corrosive
• Replaces most cut gaskets
• Can be used as a gasket maker or dressing
• Non-flammable, Non-toxic
• Low odor
TYPICAL APPLICATIONS
• Valve covers
• Transmission pans
• Oil pans
• Timing gear covers
• Differential covers
DIRECTIONS FOR USE
For assembly as a form-in-place gasket
1.
Remove all previous material from mating surfaces.
Permatex

Gasket Remover or Silicone Stripper is
recommended for most materials.
2.
For best results, clean and dry all surfaces with a
residue-free solvent, such as Permatex

Brake and
Parts Cleaner.
3.
Cut nozzle to desired bead size, 1/16“ to 1/4“ in
diameter. A 1/8” bead is usually sufficient for most
applications.
4.
Remove cap, puncture tube or cartridge seal and attach
extension nozzle.
5.
Apply a continuous and even bead of silicone to one
surface, first tracing the internal areas of the gasket
configuration, then all surrounding bolt holes as shown
below:
6.
Assemble parts immediately while silicone is still wet.
Secure or tighten to recommended torque specs.
7.
Re-torque will not be necessary after the product has
cured.
For assembly as a gasket dressing
1.
Repeat steps 1 through 4 as in previous section.
2.
Apply a thin film of silicone to one surface to be sealed.
3.
Place the pre-cut gasket onto silicone film.
4.
Apply a second thin film to pre-cut gasket surface.
5.
Remove any excess and assemble parts immediately.
Note: Product is not recommended for use as a cylinder
head gasket or head gasket sealant.
Instructions for PowerBead
1.
Clean and dry all flange surfaces to be sealed.
2.
Remove black cap from top of extension nozzle.
3.
Turn nozzle extension one complete turn (360°)
counterclockwise.
4.
Depress finger trigger and apply a continuous 1/16 inch
to 1/8 inch PowerBead to one surface.
5.
Assemble parts immediately while silicone is still wet.
6.
Finger tighten flange only until material begins to seep
out the sides of the flange.
7.
Allow to set for at least two hours and re-torque at least
one quarter to one half turn.
8.
For best results, allow to cure overnight.
9.
To close, turn extension nozzle clockwise until tight
(about one full turn). Wipe off excess material from
nozzle and replace black cap.
Storage of Unused Product
1.
Create a “Silicone Plug” by allowing excess material to
extend beyond the extension nozzle or aerosol tip to
cure, sealing and protecting the remaining product from
moisture. For reuse, simply remove the cured product
from the tip.
2.
For PowerBead dispensers, you may store remaining
product using either the above “silicone plug” method or
using the included plastic cap.
