Permatex 82180 Ultra Black RTV Silicone Gasket 85g



Permatex 82180 Ultra Black Oil Resistance Rtv Silicone Gasket Maker 85g

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.
  • Improved oil resistance
  • Sensor safe, non-corrosive
  • Good adhesion and flexibility
  • Replaces most cut gaskets
  • Can be used as a gasket maker or dressing
  • Non-flammable, Non-toxic
  • Low odor
  • Oil pans
  • Transmission pans
  • Valve covers
  • Valves and guides
  • Timing gear covers
  • Differential covers

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. A 1/8” bead is usually sufficient for most
  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
  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)
  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.

For Cleanup

  1. Remove uncured product from parts and hand-tools with
    Permatex® Fast Orange® Wipes or Fast Orange® Hand
    Cleaners. If skinned over, break film with a dry cloth to
    remove as much as possible. Remove the remaining
    material with Permatex® Gasket Remover.
  2. Clean hands with a dry cloth or Permatex® Fast
    Orange Hand Cleaner.


Permatex Ultra Black Gasket Maker cures on exposure to
moisture in the air. The product dries tack free in two hours
and fully cures in 24 hours. Cure times will vary with
temperature, humidity and gap.
