Can Spigot Carbon Steel SF Type fittings be used safely with rubber, non-reinforced, and textile-reinforced plastic hoses with external steel braid?

Yes. The Spigot Carbon Steel SF Type fittings with flat sealing are suitable and safe for use with rubber hoses, non-reinforced plastic hoses, and textile‑reinforced plastic hoses that have an external steel braid. Their robust carbon‑steel construction with a galvanized protective coating provides enhanced wear and corrosion resistance, while the flat sealing design ensures reliable, low‑pressure performance and secure connections in flexible hose assemblies. Common applications include sanitary installations, fuel delivery, compressed air lines, and other technical systems requiring durability and safety. For best results and a leak‑free joint, use UM type nuts (EC‑105…) recommended for compatibility and easier assembly.
