Is the Stainless Steel Hose End for High-Pressure Gases, W24.32x1/14" DIN477, TLWW170 compatible with standard nitrogen regulators and fittings?

Yes. The Stainless Steel Hose End for High-Pressure Gases, W24.32x1/14" DIN477, TLWW170 is compatible with standard nitrogen regulators and fittings that use the Whitworth W24.32x1/14" (DIN477-1 no.10) connection. It is specifically designed for nitrogen service, meets PN-81/M-69229 (DIN477) standards, and provides a secure, leak‑free connection for PTFE high‑pressure hoses. Constructed from AISI 304 stainless steel (fitting) with a brass nut, it offers suitable pressure and chemical resistance for laboratory, medical, and industrial gas distribution applications.

Can the Stainless Steel Hose End for High-Pressure Gases, W24.32x1/14" DIN477, TLWW170 be used with oxygen or other reactive gases besides nitrogen?

Stainless Steel Hose End for High-Pressure Gases, W24.32x1/14" DIN477, TLWW170 is specified and dedicated for nitrogen service. Its materials (AISI 304 stainless steel fitting and brass nut) and design meet PN-81/M-69229 (DIN477-1 no. 10) and ensure reliable, leak‑free connections for PTFE hoses in high‑pressure gas transfer. However, suitability for oxygen or other reactive gases cannot be assumed from this description: oxygen service imposes stricter requirements (oxygen-cleaning, absence of combustible contaminants, and often use of oxygen-compatible materials and lubricants). Brass contains copper and zinc, which can pose risks in high‑pressure oxygen environments, and the product is not stated as oxygen‑cleaned or approved for reactive gases. Therefore, do not use this fitting with oxygen or other reactive gases unless the manufacturer explicitly certifies oxygen compatibility, confirms oxygen cleaning and appropriate materials, and provides pressure/temperature ratings for those gases. For safety, consult the supplier/manufacturer for certification and follow applicable oxygen-handling standards before any such use.
