Gear Oil RTV Gasket Maker, 3 oz.

PRODUCT DESCRIPTION
Permatex Gear Oil RTV Sealant is a single component, room temperature, vulcanizing, gasketing compound designed to provide reliable “formed-in-place” gaskets for mechanical assemblies. The product has been specially formulated to withstand the harsh gear oil environment found in many differentials and transfer cases that destroys normal RTV materials. Normal RTV’s are broken down by friction modifiers found in many gear oils and causes leaks and seepage. This specialty RTV has been tested to stringent OEM specifications to ensure complete sealing as a gasket maker. It seeks and seals leak paths that cut and molded gaskets cannot. This product can be used to seal cut gaskets. 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.

PRODUCT BENEFITS
- Maximum gear oil resistance
- Safe for use with friction modifiers
- Sensor safe, non-corrosive
- Good adhesion and flexibility
- Replaces most cut gaskets
- Can be used as a gasket maker or dressing
- Non-flammable
- Low odor

TYPICAL APPLICATIONS
- Specially designed and formulated for differentials and transfer cases

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 but 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. A 1/8” bead is usually sufficient for most applications.
4. Remove cap, puncture tube 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.
6. Assemble parts immediately while silicone is still wet.
7. Finger tighten flange until material begins to seep out the sides of the flange.
8. Allow to set for at least one hour and re-torque 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 flange 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.
