Hose fittings are parts used to connect hoses to equipment, among the fittings used to connect piping. In other applications, we may connect hoses of different sizes or repair damaged parts. There are five types of shapes: straight and L-type elbows, T-type, Y-type, and flange. Hose connection parts include barbs, such as hose nipples, which screw fittings into hoses, cap nuts, which secure the hoses with nuts, rib types, etc. Barbs are easy to install, but cap nuts are a less risky water leak. The material used is stainless steel with excellent corrosion resistance and durability, resin with excellent corrosion resistance, PVC with excellent strength and versatility, etc. The compatible fluids such as water, air, chemicals, oils, powders, etc. vary depending on the material.
