Barbed stems provide a tighter seal on flexible and semirigid hoses when used with a hose clamp, crimp sleeve, or ferrule. Temperature and pressure performance Temperature range: 100 to +300 degrees F Maximum working pressure: 350 psi Brass barb union enhances corrosion resistance, ductility at temperatures, and low magnetic permeability Material and construction Body material: Aluminum alloy, designed to operate at temperatures and pressures Brass barb union component specification included for improved performance in demanding conditions Connection and fit Connection length is designed to be long enough to insert the hose and help secure the connection with a clamp, crimp sleeve, or ferrule 23 practical use scenarios Industrial cooling or fluid transfer lines in equipment and manufacturing where temperature tolerance and up to 350 psi are required, using hose clamps or crimp assemblies Automotive or machinery engine bays for coolant or air lines that experience elevated temperatures and moderate pressures HVAC, irrigation, or generalpurpose fluid lines in controlled environments where corrosion resistance and low magnetic permeability of the brass barb union add durability Note: This hose barb fitting is compatible with hose clamps, crimp sleeves, or ferrules and is designed to provide a reliable seal under the stated temperature and pressure conditions.
