RAF oxygen mask question........
A good sortie was characterised by the nonchalant carriage of the 'bone-dome' by holding the oxgen delivery tube, with the helmet, rucksack style, bouncing on the back.
...after a bad sortie, the helmet was transported a la 'Bobby Charlton'.

O/K, just to clarify what I think is correct........
1/ Pre-Harrier types without PEC connector have the Inlet Warning Connector at the end of the mask O2 hose that you cannot breath through unless connected correctly to an O2 system. (aircraft mounted regulator).
2/ Early Harriers had a connector at the end of the mask O2 hose that connects to the man mounted regulator with the hose down to the PEC connector.
3/ Later Harrier types have a connector at the end of the mask O2 hose that connects directly into the end of a hose from the PEC connector (aircraft mounted regulator).
Just noticed in photos that even though the GR.7/9 were useing the later type, 'T-bird' aircrew still had the man mounted regulator setup.
Stitchbitch is kindly working on getting me the (3rd type) male connector that fits on the end of the Mask O2 hose.
I don't think I'm as confused as I was unless there's more to add?
cheers,

Hope this helps
1-Top connector is known as the Mk7A oxygen quick disconnect half coupling (Bayonet connector) the part you need to fit the mask tube is the male Mk7 bayonet connector.
2-On the mini-man mounted regulator system the oxygen mask hose connector fitted to the top of the regulator with the PEC 1/2 inch diameter oxygen supply hose being attached to the base of the regulator and the other end to the PEC man portion sole (Base) plate by a screw thread and captive nut i.e. spanner job to remove regulator.
3-Never worked with Harriers but would imagine on later Mks that the oxygen regulator is fitted to the ejection seat to interface with the aircraft portion of the PEC as with Hawk and Tornado.
P.S The mini-man mounted system was not compatable with normal low pressure oxygen systems as it operated at 70 P.S.I. (Input to regulator)
Tashengurt -Thanks for the mention, only just found this post as I have been away

Thanks for the info Squipper,
either of the types will do me, Mk7 male connector or the connector that fits into the top of the man mounted regulator (probably best but harder to find).

Hi D John
The mask tube connector that fitted to the top of the 317A mini-man mounted regulator was unique to that system and as far as I am aware would not be compatable with anything but that regulator. The oxygen mask ('V' mask type) tube is not the usual black rubber tube but is green silicone and foam covered and is not extendable or flexible.
The Mk7/7A connector has been the standard PEC /oxygen mask connector ever since PECs came into use over 50 years ago so the Mk 7 connector you require should be very easy to source
Good luck with your quest..
