2pcs Brass Barb Reducing Hose Fitting Straight Connector 8mm to 6mm for Boat Air Hose

Made of brass for corrosion resistance, high-temperature ductility, and low magnetic permeability. Connects two hoses of different diameters in a straight run. Used to connect air, water, fuel, oil, and inert gas lines quickly and easily. The grooved stems create a tight seal on flexible and semi-rigid hoses when used with a hose clamp, crimp sleeve, or ferrule (not included). This fitting has barbed connections at both ends for joining two hoses.
