Blank Top Jaws are manufactured to extremely close tolerances to assure proper fit onto micro centric chucks. The blank jaws are typically machined on the chuck under load to suit the workpiece to be clamped. The steel jaw blanks can be carburized after rough machining, and then finish ground on the chuck.
Blanking plugs are used to seal bulkheads or panels where optional lightning protectors are not installed. Blanking plugs serve to block off the sensor bores where no sensor is used. These plugs are useful for pressure testing the tubing string or to abandon certain zones within a well. Blanking plugs use a removable prong that is inserted into the plug to equalize the pressure across the plug and to complete the fluid seal. Blanking plugs are fitted in the engine intakes & jet pipes and the tail parachute retrieved & stowed for transport. Blanking plugs are fitted to the heater hoses.
