Crosses are manufactured with a flange on each end of an “X” shaped section of tubing. Crosses are available in 3 basic configurations: 4-Way, 5-Way, and 6-Way. The flanges on plain crosses are all from the same family. Reducer crosses change sizes within the same family of flanges. Hybrid Adapter crosses intermix flange families. A&N manufactures standard crosses in 304L stainless steel, 316L stainless, and aluminum. Other materials and flange configurations are available on request.
