Can the Brass Steam Hose End Adapter with Female Thread, BOSS GFB Type withstand continuous operation at 210–230°C and up to 18 bar?

Yes. The Brass Steam Hose End Adapter with Female Thread, BOSS GFB Type is specified for continuous operation up to 230°C and for working pressure up to 18 bar. It is designed with a conical surface matching the spherical sealing face to ensure tightness under high pressure and elevated temperatures, and is explicitly rated resistant to saturated steam at +210°C with an operating temperature up to +230°C. The wing nut allows quick, tool-free tightening while providing durable, secure connections suitable for professional steam systems.

Is the Brass Steam Hose End Adapter with Female Thread, BOSS GFB Type compatible with other steam fittings that use larger wing nut threads for varied installation layouts?

Yes. The Brass Steam Hose End Adapter with Female Thread, BOSS GFB Type is compatible with other steam fittings that use larger wing nut threads. The adapter’s wing nut thread is intentionally larger than the GFB internal thread, allowing it to mate with a wider range of spherical-end fittings and varied installation layouts. Its conical-to-spherical sealing surface ensures a tight, durable seal under high pressure (up to 18 bar) and high temperatures (resistant to saturated steam at +210°C, operating to +230°C). The tool-free wing nut also enables quick assembly and reconfiguration in the field, making it practical for flexible system arrangements while maintaining safety and reliability in professional steam systems.
