The Rapco Vacuum Pump wrench is the tool of choice to remove and replace vacuum pump flange nuts. The shank is bent at the perfect angles to provide easy access to those tight areas between the pump and the accessories nearby. And the open end head is precision laser cut to provide a close tolerance fit on the nut. It’s manufactured from hardened steel alloy and nickel plated for corrosion resistance. The ergonomic handle is coated for a comfortable, slip resistant grip. 1 lbs (0.5Kg) shipping weight.
