Ex Core And Blow Out Covers: These, and the several type of covers listed above, use an engineered gasket system in conjunction with our Quik-Lok® Cam Bolts or Nuts. The system can be designed around existing Covers to reduce costs. The System results in a fast, reliable, and leak-tight installation for traditionally troublesome leak paths
Fuel Transfer Tube Closure Systems: This design uses Preferred Engineering's unique Quik-Lok® Toggle Bolt. These high-strength quick-throw cam fasteners are coupled with an engineered dual gasket system. Together, the Closure System replaces the standard 20-24 bolts with 4 Toggles. The completed system can be leaktested between the seals to assure proper installation. The result is a dramatically reduced Fuel Transfer Cover installaton time with reduced dose.
