Steel Medium Shank Combination Nipple, 0.75 Inch ID Hose Barb To 3/4-14 Male NPT

For hose fit, the barb is made for 0.75 inch ID hose, so it matches a 3/4 inch inside diameter whip hose. On the other end you get a 3/4-14 male NPT thread for tying into a female NPT port or coupler.

Heat-treated steel is exactly what makes this one worth using on vibrating equipment. Pavement breakers and air drills are specifically what this fitting is built around, so the constant shaking and stress that kills standard fittings tends not to be an issue here. The zinc plating adds a layer of corrosion protection on top of that, which helps when fittings are taking a beating in rough conditions. Just make sure your hose ID measures 0.75 inches and your tool port is a 3/4-14 NPT thread, and you should be in good shape.
