Is the Steam hose end with GW NPT, brass GF BOSS suitable for saturated steam at 18 bar and up to +230Â°C?

Yes. Steam hose end with GW NPT, brass GF BOSS Format is suitable for saturated steam at 18 bar and up to +230Â°C. The product description specifies NPT internal threaded ends for rubber hoses designed for steam, assembled with the BOSS SBC type steam clamps, and comprising a spherical brass end (GB), wing nut (B) with NPS internal thread, and GFB adapter with matching threads and a conical polymer or copper insert. This design provides a steam-resistant, high-temperature seal and allows tool-free tightening via the wing nut. Rated working pressure is 18 bar for saturated steam up to +210Â°C and the operating temperature is specified up to +230Â°C, matching your stated conditions.

Can the Steam hose end with GW NPT, brass GF BOSS be used with ribbed-tail hoses and BOSS SBC clamps at 18 bar?

Yes. Steam hose end with GW NPT, brass GF BOSS Format can be used with ribbed-tail hoses and BOSS SBC clamps at 18 bar. The design (ribbed tail for rubber hose, lock for installation with BOSS SBC steam clamps, three-part assembly with spherical GB spout, wing nut B with NPT internal thread, and GFB adapter with matching threads and conical polymer/copper insert) provides a tight, steam-resistant, high-temperature seal rated for saturated steam at 18 bar (+210Â°C) and up to +230Â°C. Ensure correct hose diameter, proper clamp tightening and routine inspection for wear or seal degradation.

How do I tighten or loosen the Steam hose end with GW NPT, brass GF BOSS using only the wing nut under steam conditions?

How do I tighten or loosen the Steam hose end with GW NPT, brass GF BOSS using only the wing nut under steam conditions? 1. Ensure safety first: depressurize and cool the line as much as possible; wear heat-resistant gloves and eye protection. Work fast but carefully under permitted steam conditions. 2. Hold the spherical end GB steady (use a wrench on the hose tail if needed) so the assembly does not twist the hose. 3. Use only the wing nut B to turn the joint. To tighten: rotate the wing nut clockwise until it seats against the adapter GFB; continue turning by hand until you feel firm resistance as the conical insert compresses the spherical end and creates the steam-tight seal. Do not overtightenâstop when resistance increases significantly. 4. To loosen: rotate the wing nut counterclockwise by hand until it unthreads from the GFB adapter enough to relieve compression on the conical insert. Once loose, you can pull the hose tail out. 5. If the wing nut is too hot, use heat-resistant gloves or a cloth; do not use pliers on the wing nut (may damage threads). If the wing nut wonât turn by hand, apply steady, even forceâavoid sudden jerks. 6. After any reassembly under steam conditions, check for leaks at low pressure first, then bring to operating pressure and inspect. If leakage persists, depressurize and re-seat the joint; replace worn polymer insert or damaged threads. Steam hose end with GW NPT, brass GF BOSS Format

Additional information

Material	B – brass (bronze)

NPT internal threaded ends for rubber hoses for steam, with a ribbed tail for the hose, with a lock – for installation in the hose using BOSS SBC type steam clamps. The complete end consists of three parts – a spherical end GB with a spout (“tail”) for the hose, a wing nut B with a special internal thread (NPS), and a special adapter GFB with an external thread (NPS) matching the nut and an internal thread of the same size as the end. The GFB adapter has a conical polymer or copper insert that works with the spherical end. This creates a tight, steam-resistant, and high-temperature connection that is also easy to unscrew and screw without the use of special tools, using the wing nut. Material: brass. Working pressure: 18 bar (+210°C) – saturated steam. Operating temperature: up to +230°C.
