Is the Quick-connection socket DN5.5 with valve, threaded, hardened steel, series 1423KA compatible with ISO 6150B and safe for compressed air up to 35 bar?

Yes. Quick-connection socket DN5.5 with valve, threaded, hardened steel, series 1423KA is compliant with ISO 6150B (A-A-59439, MIL C-4109) and rated for a working pressure of 35 bar, making it suitable and safe for compressed air up to that pressure. The socket features QPQ-hardened steel body, ULTRA-FLOW valve, NBR seals, stainless internal parts, and an operating temperature range of -20Â°C to +100Â°C, supporting typical industrial compressed-air use.

Can the Quick-connection socket DN5.5 with valve, threaded, hardened steel, series 1423KA be used with other fluids besides compressed air?

Quick-connection socket DN5.5 with valve, threaded, hardened steel, series 1423KA is designed primarily for compressed air but can be used with some other fluids if compatibility conditions are met. Constraints: - Seals: NBR (nitrile) compatible with oils, hydraulic fluids, water, and some fuels, but not with strong acids, ketones, or high-aromatic hydrocarbons. - Materials: QPQ steel, nickel-plated brass, stainless steel components are generally corrosion-resistant but may react with aggressive chemicals. - Temperature: -20Â°C to +100Â°C limits use with hot fluids or those requiring wider temperature range. - Safety: Not certified for gases/liquids under certain standards; verify pressure (working 35 bar) and flow requirements. Recommendation: Consult fluid compatibility charts and the manufacturer for specific chemicals and safety certifications before use with fluids other than compressed air.
