Ultra
Permatex Ultra Black retains high flexibility and oil resistant properties through use of a patented adhesion system. Ultra Black is sensor safe, low odor, and non-corrosive with resistance to oil, shop fluids, and vibration. This sensor-safe, low odor, non-corrosive formula meets performance specifications of OE silicone gaskets and can be used on high flexibility and high oil resistant applications such as timing covers, transmission pans and oil pans.
- High flexibility and oil resistance
- Sensor-safe, non-corrosive formula
- Resist to powertrain fluids
- Eliminates the need for pre-formed, pre-cut gaskets
- OEM specified and approved for dealership warranty requirements
Optimum
Permatex Optimum Black combines MAXIMUM OIL RESISTANCE with MAXIMUM FLEXIBILITY. Today, we see components changing and unlike materials meeting (plastic/steel, aluminum/steel, etc.), all with different rates of expansion and contraction. In addition, with technology advancing, regulations and requirements tightening, we see thinner metals, fewer fasteners, and wider spread bolt patterns. The strength and flexibility of Optimum Black handles the changes and added stresses that exist between today’s lightweight, high performance, and premium component assemblies. Optimum Black is sensor safe, low odor, and non-corrosive with resistance to oil, shop fluids. It is one of the most advanced, maximum flex, maximum oil resistant RTV silicone gasket makers available. The best part, now it is up to 90% easier to disassemble and cleanup.
- Maximum flexibility and maximum oil resistance
- Sensor-safe, low odor, non-corrosive
- 15% stronger and 60% more flexible than Ultra Black
- Up to 90% easier to disassemble and clean up.
- Resistant to auto and shop fluids, and vibration
- Meets performance specs of OE silicone gaskets
