Is the Hose end for high-pressure gases with thread according to DIN477, stainless steel, type ZBW170 suitable for oxygen and carbogen service with Gâ3/4" internal thread?

Yes. The Hose end for high-pressure gases with thread according to DIN477, stainless steel, type ZBW170 is suitable for oxygen and carbogen service with Gâ3/4" internal thread. The product description explicitly lists application: oxygen, carbogen and specifies connection according to DIN477 (PN-81/M-69229) with internal thread G-3/4" (3/4" BSP). Materials.AISI 304 stainless steel fitting and brass nut.are commonly used for gas fittings; however, for pure oxygen service higher-grade stainless (e.g., AISI 316L) and all-metal, clean, oil-free assembly are often preferred to minimize fire risk. If the installation must meet specific industrial, medical or regulatory oxygen-service standards (cleanliness, oil/grease-free handling, brazing/welding restrictions), confirm the component has been cleaned and certified for oxygen service and that system procedures follow oxygen-compatible assembly and testing.

Can Hose end for high-pressure gases with thread according to DIN477, stainless steel, type ZBW170 be used with oxygen and carbogen in systems with Gâ3/4" internal thread?

Yes. Hose end for high-pressure gases with thread according to DIN477, stainless steel, type ZBW170 can be used with oxygen and carbogen in systems with Gâ3/4" internal thread. The product description specifies it is an end fitting for highâpressure gases with internal thread Gâ3/4" (BSP) per PN-81/M-69229 (DIN477â1 no.9) and lists application: oxygen, carbogen. Material (AISI 304 steel fitting, brass nut) is compatible for these gases when installed and maintained per relevant safety standards. Ensure proper cleaning for oxygen service, correct sealing, and conformity with local regulations before use.

Can Hose end for high-pressure gases with thread according to DIN477, stainless steel, type ZBW170 tolerate oxygen-rich environments when fitted with a brass nut?

Hose end for high-pressure gases with thread according to DIN477, stainless steel, type ZBW170 cannot be recommended for oxygen-rich environments when fitted with a brass nut. Rationale: - The product description lists the fitting body as AISI 304 stainless steel and the nut as brass. In oxygen service, all materials exposed to high-purity or high-pressure oxygen must be assessed for ignition risk, compatibility and cleanliness. Brass (a copperâzinc alloy) has a higher risk of adiabatic compression ignition and can be more reactive under high-pressure oxygen than stainless steels specifically qualified for oxygen service. - Standard practice for oxygen service typically requires oxygen-cleaned components and materials with proven oxygen compatibility (e.g., specific stainless steels, copper-free alloys, or components specifically certified for oxygen service). The description does not state oxygen cleaning, oxygen compatibility testing, or certification. - Although the application list includes âoxygen, carbogen,â that alone is not sufficient to assure safe use with brass in oxygen-rich environments without explicit oxygen-cleaning, compatibility certification, and operating-pressure limits. Brass parts are often avoided or require special qualification for high-pressure oxygen systems. Recommendation: - Do not use Hose end for high-pressure gases with thread according to DIN477, stainless steel, type ZBW170 with a brass nut in oxygen-rich or high-pressure oxygen systems unless the manufacturer provides explicit oxygen compatibility certification, oxygen-cleaning documentation, and approved pressure/temperature limits for the brass nut. - If unavailable, request a version with oxygen-compatible materials (e.g., fully stainless steel nut certified for oxygen service) and documented oxygen-cleaning, or obtain manufacturer confirmation in writing.
