Permatex Ultra Black 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 provide
increased oil resistance and complies with extended warranty
requirements. OEM Specified.

DIRECTIONS FOR USE
For assembly as a form-in-place gasket
1. Remove all previous material from mating surfaces.
Permatex® Gasket Remover is recommended for most
materials, not for plastics or painted surfaces.
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. An 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.
7. Finger tighten flange only until material begins to seep
out the sides of the flange.
8. Allow to set for at least two hours and re-torque at least
one quarter to one half turn.
9. For best results, allow to cure overnight.
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.
