Aircraft maintenance including shock strut inflation and tyre servicing operations.
-
Laboratory research setups requiring heavy-duty delivery from high-capacity 300bar gas packs.
EWS Expert Note
When connecting the NEVOC side-entry stem to a 300bar nitrogen cylinder valve, always inspect the seating face for microscopic debris before hand-tightening the nut. Never use thread sealing tape or oil-based lubricants on high-pressure gas threads. Torquing the connection with a correctly sized open-ended spanner rather than an adjustable pipe wrench prevents rounding of the brass flats and ensures a gas-tight seal capable of holding 300bar static pressure safely.
Pros & Cons
Pros:
-
Direct NEVOC side-entry fitting eliminates unsafe adapter usage on 300bar cylinders.
-
Heavy-duty alloy housing and high-impact gauge covers provide excellent physical durability.
-
High-precision internal diaphragm engineering delivers stable outlet flow even at maximum delivery pressures.
Cons:
Technical FAQs
How do I confirm if my 300bar nitrogen cylinder manifold requires a NEVOC connection?
NEVOC (New European Valve Outlet Connection) fittings are the standard safety connection for 300bar gas cylinders across Europe. If your cylinder valve external thread measures approximately 30mm with a specialised internal seating surface, this side-entry NEVOC regulator will connect directly without requiring auxiliary brass adapters.
Can this regulator handle rapid-discharge purging cycles without freezing?
While engineered for heavy-duty gas delivery, extremely high flow rates over sustained periods cause dramatic pressure drops that induce thermal cooling. For continuous ultra-high-flow nitrogen purging, monitoring line pressure is recommended to avoid internal icing, though its robust brass-alloy valve assembly handles standard continuous purge cycles easily.
What compliance standards apply to this high-pressure nitrogen regulator in the UK?
The HL800 FabMaster Elite regulator is manufactured in compliance with BS EN ISO 2503 for gas pressure regulators and features gauges compliant with BS EN 5171. Built under certified BS EN ISO 9001 quality systems, it carries full UKCA/CE markings required for professional workshop safety compliance.
