OPTIMUM BLACK Gasket Maker; 3.35 oz tube with 2 nozzles
OPTIMUM BLACK combines maximum oil resistance with high 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 these changes and added stresses that exist between today's lightweight, high performance, and premium component assemblies. It is sensor safe, low odor, and non-corrosive with resistance to oil, shop fluids, and vibration. Also, an extra nozzle is included adding convenience, eliminating the hassle of a clogged nozzle, and allowing multiple uses of each tube without loss of product. OPTIMUM BLACK is one of the most advanced, high flex, maximum oil resistant RTV silicone gasket makers available.

Directions:
  1. For best results, surfaces should be clean and dry.
  2. Cut nozzle and apply a continuous 1/16 to 1/4 (2 to 6mm) bead of silicone to one surface, surrounding all bolt holes. Assemble parts immediately while silicone is still wet. Finger tighten until material begins to squeeze out around flange.
  3. Let dry for one hour then tighten to torque specifications.
  4. Allow 24 hours to fully cure before filling with fluids or returning to service.
  5. Replace cap after use.

NOTE: Not recommended for use on head gaskets or parts in contact with gasoline.
