Brass multipurpose rigid barbed hose fittings provide good strength, ductility, and corrosion resistance. They are more heat-resistant than 6061-T6 aluminum rigid barbed hose fittings. They have various connection types on one end with raised ridges (or barbs) on the other end that grip the inside of hoses to hold them in place. They are secured with a clamp or crimped ferrule for a leak-resistant seal.
