I am not sure on the McMaster parts, but the four CEJN parts that I use are readily available from John at Northeast Scuba Supply.

EXCEPT!!! These are NOT really CEJN compatable.... they DO NOT FIT standard CEJN fittings without a little "encouragement" and perhaps some emery paper. The are marketed as "Seaquest" compatable, for the Air-Source, and are "very slightly" different. Just be cautious and try EVERY hose on for compatability. The Hansen manufactured connectors used by Seaquest fit true CEJN no sweat. BUT true CEJN hoses (Unisuit, Viking, etc) DO NOT FIT the Seaquest adapters "well" and in some cases "not at all".

McMaster-Carr sells CEJN as "European Shape Quick Connects" but only have them in steel.

I bought a bunch of stuff from Northeast SCUBA and am now removing the nipples from service. I'll talk to si-tech and just order the correct parts (the solid nipples designed for use on a drysuit valve) for the one side, and then the Seaquest couplings from NES will fit fine. It's a case of "one way interchangability". I'd hate for this to only become obvious in a gas-sharing emergency one day.

Matrix:

CEJN Males fit: Seaquest, Hansen, Viking, Poseidon, Apeks, Zeagle, Ocean Reef, and all similar.

Seaquest males fit: Hansen and Seaquest. The DO NOT fit Viking, Poseidon, Apeks, Zeagle, Ocean Reef, etc.

If you find GENUINE parts from CEJN (thru si-tech) then you will have full compatability.

NONE of them (sadly) fit the nice QD that Golem sells for BOV's...... sorry.

And you see a girls brown body dancing through the turquoise, And her footprints make you follow where the sky loves the sea. And when your fingers find her, she drowns you in her body, Carving deep blue ripples in the tissues of your mind...... Last edited by Dave Sutton : 11th June 2007 at 10:30.
