What are the differences between beaded hose fitting and barbed hose fitting?
The major difference is in the shape. Beaded hose fitting has a raised lip on one end that grips the inside of the hose to hold it in place. Barbed hose fitting has one or more continuous ridges or bumps that are used to grip the inside diameter of a tube and seal the connection. Having the right number of barbs in design is important as it determines the gripping quality. You can find the difference in shapes of beaded hose fitting and barbed hose fitting in the pictures below.

Both beaded hose fittings and hose barb fittings meet SAE J1231 specifications. Both styles of fitting (barbed and beaded) require a clamp (specified in SAE J1508) to ensure proper operation and performance. They are used to convey water, coolant and compressed air in low-pressure automotive and hydraulic applications. They are available with NPTF, BSPT, SAE straight thread and metric threads for both inch and metric size hoses.
