Is the Quick-connection socket DN2.7 with bulkhead valve, with hose end, brass, series 20KA compatible with oxygen or other flammable gases?

Quick-connection socket DN2.7 with bulkhead valve, with hose end, brass, series 20KA is designed for water, air, nitrogen and other non-flammable gases. It uses brass components, AISI steels, and NBR seals and is specified for non-flammable media. Because oxygen and other oxidizing or flammable gases require materials, lubricants and seals certified for oxygen service (to avoid ignition, rapid combustion or degradation), and because NBR and standard brass/steel combinations are not rated for oxygen service, this product should not be considered compatible with oxygen or other flammable/oxidizing gases. Use only fittings explicitly specified and certified for oxygen/flammable-gas applications.

Does the Quick-connection socket DN2.7 with bulkhead valve, with hose end, brass, series 20KA require special maintenance intervals for use with compressed nitrogen?

Quick-connection socket DN2.7 with bulkhead valve, with hose end, brass, series 20KA Format; based on the provided specification, no special maintenance intervals are explicitly required for use with compressed nitrogen. The coupling is rated for nitrogen application, made of brass with NBR seals and stainless steel internals, and its operating temperature and pressure ratings (working pressure 35 bar, temp -20Â°C to +100Â°C) are compatible with typical nitrogen service. Standard maintenance best practices should be followed: regular visual inspection for wear, seal degradation or damage, periodic leak testing, and replacement of NBR seals if exposed to oils/chemicals or aging. Increase inspection frequency if used near pressure/temperature limits or in harsh environments.
