HIGH PRESSURE OXYGEN FILL ADAPTERS 

Newbow Aerospace is renowned as the global aviation market leader for its wide range of aircraft inflation equipment. 
 
We manufacture and supply two common types of oxygen fill adapters that allow direct connection to the aircraft oxygen fill port. 
 
The oxygen adapters are manufactured from brass and then oxygen cleaned and tested to the applicable ASTM standard. 
Each individual adapter is supplied fully sealed in a polythene package and labelled accordingly 
 
It should be noted that the common oxygen fill adapter supplied to many of our World-wide customers is item NB1438-OCA. This specific adapter seems to be a more universal application suited to many differing aircraft types. 
Oxygen adapter NB4110-417A is more specific to some Boeing aircraft. 
 
When working with oxygen gas, safety must always be observed. The AMM should always take precedence followed by local oxygen gas procedures. 
Advantages 
 Direct Connection to Aircraft Oxygen Port 
 ¼” BSP Inlet Thread for Fill Hose Connection 
 Heavy Duty Brass Material 
 Oxygen Cleaned & Compliant 
 Group Certificate of Conformity
