Pressure-Lok air chuck from Northfield Precision Instrument uses no air tubes, hoses

Northfield Precision Instrument Corp. has developed the Pressure-Lok chucking system. It is charged with air by a special handle and holds air pressure for more than two weeks, eliminating the need for air tubes and hoses.

The air chuck can be mounted to rotary tables with no through-hole, tombstones, pallets, or transfer systems. It can be used in any machining operation that does not have an air tube near the machine.
