The North American Industry Standard for oxygen fittings are called ‘CGA-540’ (Compressed Gas Assn. fitting No. 540). Aircraft with built-in oxygen systems do not usually use the heavy fittings, instead special lighter-weight fill fittings have been developed. We have transfiller fittings for easy refilling of your built-in system from standard CGA-540 oxygen systems. The adapters shown are for the aircraft fillers. The (N) is for ‘Nipple’ and the (S) is for ‘Socket’ on the CGA-540 end. An industrial cylinder has a socket. Microparticle filters are used and an O-ring is on the 540 nipple for an airtight fit by hand.
TA-380-S Transfiller adapter, adapts CGA-540 to the AN-800 (3/8-24) fitting .
Commonly known as the MS22066 and MS22035 filler ports. A socket is on the CGA-540 end to attach to transfiller lines. This is our most common adapter.
