Tempest AA716 Dry Air Pump Wrench  

The Tempest AA716 is made of case hardened steel, with nickel-chrome plating for corrosion resistance. It comes with a slip resistant vinyl grip and a rare earth magnet that allows for efficient and easy installation of those hard-to-get-to install nuts. 

The AA716 wrench works on all 200, 3200, 240 and 400 series vacuum pumps.
