Is the 90° Elbow End with Nut, Carbon Steel, RBU Type suitable for use with rubber and textile-reinforced plastic hoses?

Yes. The 90° Elbow End with Nut, Carbon Steel, RBU Type is suitable for use with rubber hoses and with plastic hoses that are non-reinforced or reinforced with textile and an external steel braid. It is designed for low-pressure applications, offers corrosion and wear resistance, and provides secure, leak-free connections with easy assembly.

Can the 90° Elbow End with Nut, Carbon Steel, RBU Type be used in potable water or food-grade systems?

No. The 90° Elbow End with Nut, Carbon Steel, RBU Type is manufactured from galvanized carbon steel and is described for low-pressure applications such as sanitary fittings, fuel distribution, and air supply systems with rubber and textile-reinforced plastic hoses. There is no indication that its materials, coatings, or seals meet potable water or food-grade certifications (e.g., NSF/ANSI, WRAS, FDA). Galvanized carbon steel and typical rubber sealing elements can leach contaminants and are generally unsuitable for direct contact with drinking water or food. For potable water or food-grade systems, use fittings specifically certified for those applications and made from approved materials such as stainless steel (food-grade grades), brass with appropriate certification, or components with verified food-safe seals.
