Can the Carbon Steel Tube End, RST Type be used with rubber and textile-reinforced plastic hoses without the nut supplied?

Yes. The Carbon Steel Tube End, RST Type can be used with rubber hoses and with non‑reinforced or textile‑reinforced plastic hoses that have an external steel braid, even though it is supplied without a nut. Its high‑quality galvanized carbon steel construction and precise engineering are designed to provide a tight, stable connection in low‑pressure applications; this makes it suitable for flexible conduits in sanitary installations, fuel delivery systems, and air distribution networks. Ensure compatibility with hose inner/outer diameters and follow proper assembly practices and any applicable pressure or safety specifications to minimize leak risk.
