Permatex® Sensor-Safe Blue RTV Silicone Gasket (low odor formula) is a single component, room temperature vulcanizing gasketing compound designed to provide reliable "formed-inplace" 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. The original "Blue" gasketing product, refined and oxygen sensor safe and low odor. OEM Specified.

  • Size: 3 ounce, tube
  • The original Permatex® Blue now with low odor formula
  • Will not foul oxygen sensors.
  • Replaces almost any cut gasket.
  • Makes reliable "formed-in-place" gaskets that resist cracking, shrinking and migrating
  • Coats pre-cut gaskets to increase reliability
  • Temperature range -65 degree Fahrenheit to 500 degree Fahrenheit (-54 degree Celsius to 260 degree Celsius) intermittent; resists auto and shop fluids
  • Carded.

Suggested Applications:


  • Valve covers, oil pans, timing covers, water pumps, thermostat housings.

  • Valve covers
  • Timing gear covers
  • Differential covers
  • Oil pans
  • Transmission pans
  • Water pumps
  • Thermostat housings.

Directions For Use:

For assembly as a form-in-place gasket

  • Remove all previous material from mating surfaces. Permatex® Gasket Remover is recommended for most materials, not for plastics or painted surfaces.
  • For best results, clean and dry all surfaces with a residue-free solvent, such as Permatex® Brake and Parts Cleaner.
  • Cut nozzle to desired bead size, 1/16" to 1/4" in diameter. A 1/8" bead is usually sufficient for most applications.
  • Remove cap, puncture tube or cartridge seal and attach extension nozzle.
  • 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:
  • Assemble parts immediately while silicone is still wet.
  • Finger tighten flange only until material begins to seep out the sides of the flange.
  • Allow to set for at least two hours and re-torque at lease one quarter to one half turn.
  • For best results, allow to cure overnight.

For assembly as a gasket dressing

  • Repeat steps 1 thru 4 as in previous section.
  • Apply a thin film of silicone to one surface to be sealed.
  • Place the pre-cut gasket onto silicone film.
  • Apply a second thin to pre-cut gasket surface.
  • Remove any excess and assemble parts immediately.

Note: Product not recommended for use as a cylinder head gasket or head gasket sealant.

Storage of Unused Product:

  • 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.

For Cleanup:

  • 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.
  • Clean hands with a dry cloth or Permatex® Fast Orange® hand cleaner.

Properties Of Uncured Material:

  • Chemical Type: Oxime silicone rubber
  • Appearance: Blue non-sag paste
  • Odor: Low Odor
  • Specific Gravity: 1.44
  • Extrusion rate @ 25 degree Celsius, (grams/min): 280
  • Flash Point degree Celsius (degree Fahrenheit): >93 (>200)

Typical Curing Performance:

  • Permatex® Sensor-Safe Blue RTV Silicone Gasket cures on exposure to moisture in the air. The product dries tack free in one hour and fully cures in 24 hours. Cure times will vary with temperature, humidity and gap. Note: The curing process can cause corrosion to some surfaces, for critical applications use the Ultra Series silicones.

Typical Environmental Resistance:

  • Continuous, degree Celsius (degree Fahrenheit): -54 to 204 (-65 to 400)
  • Intermittent, degree Celsius (degree Fahrenheit): -54 to 260 (-65 to 500)

Chemical/Solvent Resistance:

  • The product retains effective properties in contact with automotive fluids, such as motor oil, transmission fluids, alcohol and antifreeze solutions. Note: Not recommended for parts in contact with gasoline.

General Information:

  • This product is not recommended for use in pure oxygen and/or oxygen rich systems and should not be selected as a sealant for chlorine or other strong oxidizing materials.


  • Products shall be ideally stored in a cool, dry location in unopened containers at a temperature between 8 and 28 degree Celsius (46 and 82 degree Fahrenheit) unless otherwise labeled. Optimal storage is at the lower half of this temperature range. To prevent contamination of unused product, do not return any material to its original containers.
