1set (7pcs) as the picture shown, the wrenches feature specially formed jaws that are able to contact a fitting on four opposite sides to avoid stripping and or marring an aluminum fitting's finish.
Made from 6061-T6 aluminum and anodized in various colors for easy identification, the double-ended wrenches feature a B-nut or the S-nut 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.
