AN Double Headed Wrench
Finish Line Factory’s Double-Headed wrenches represent an upgrade over our standard wrenches. Each wrench is sized to fit either the B-nut or the S-nut of each hose end. The B-nut is the part of the hose end that fastens the hose, the S-nut is the part of the hose end that fastens the fitting to the male flare.
