Specialized Tool Set for ANVIS product number 9T1001

This tool set will simplify the disassembly, reassembly, and preventative maintenance checks and services (PMCS) of AN/ AVS-6 and AN/AVS-9 night vision goggles both in maintenance facilities and in the field. The torque drivers are factory calibrated to the torque values proven by goggle manufacturing processes to provide the best lock ring, purge valve, setscrew, and tube retainer ring tightness without over-stressing. Torque lock rinds,purge valves, setscrews, and retainers with these torque drivers/adapters have proven to provide the best means for securing critical goggle parts while eliminating the breakage and thread stripping that is often associated with hand tightening.
