Fourth generation to the popular and useful Power Tank wrench. This new design keeps the slim design of the version 1.0 with all the useful features of both previous designs in a new sleeker shape. Replace your regulator, tighten 9/16" & 5/8" fittings, R&R NAL chuck on N2 shocks, R&R hex high pressure valve caps, and of course remove caps from your favorite bottled beer. Stainless steel. Features a built-in bend point to prevent over tightening of the regulator nut. Regulator nuts should be two-finger tight.
