CEJN Fittings

Divein · 10th July 2008, 17:11

Does anyone know who can supply CEJN 221 fittings in the UK? Thanks in advance.

I think I got CEJN adaptors to go on the end of a reg hose from John Hewitt in Leeds at Red Hat diving, otherwise Divers Warehouse / Otter should be able to sell you the Apeks suit hoses (CEJN female) and possibly/probably, the nipples with a 3/8 thread. Apart form that, you coudl contact Apeks for the nipples, or I got some from ebay. - search CEJN or APEKS

Robin Hood waterports in Huddersfied (?) also stock the Ocean Reef stuff, so could do you a CEJN nipple that screws right onto a 2nd stage.

Hope it helps

Hi all

I don't really get the difference between the 221 Series and the 220 Series.

The spec sheet says "Includes brass nipple (221) making this coupling suitable for water and fluids" - what do they mean?

Obviously the flow capacity of 580 lpm for 6 bar air inlet pressure is more than adequate!

The 220 series, which are very easy to find, are made of steel...

steel + water = not good

221 are brass and stainless

Thanks for that, but as I read it the 220 spec sheet it seems to imply that the coupling body, locking sleeve, valve, springs and balls are all either brass or stainless or nickel plated/.

It seems to imply that only the 220 series hardened steel Zinc plated nipple needs to be changed for a brass one 221 series for water or fluid applications?

Or have i got it completely wrong again?

Thanks guys for the links. ROHO have the Ocean Reef Quick Connection - Male Part for £20. The female parts should be easy to source. Portland Engineering do the 3/8ths screw in male nipple.

Update: 220 series has an air flow rate of 26L/min as opposed to 221 series that has 580L/min.

I just posted a short tutorial on CEJN-style q/d's here:

Oceans of Opportunity

I have a small stash of the parts mentioned in the article if anyone needs anything.PM me

OceanOpportunity · 24th August 2008, 03:15

I've put together another handful of these assy's for anyone interested...

CEJN male (top left)
Apex male (middle left)

both compatible with either CEJN 220/221 females (top 3 on right), or Apex female (bottom right).

I have a bunch of the male assemblies and the Apex females

I wrote up a short piece here: Oceans of Opportunity . would be happy to publish an expanded version here on Rebreather World, but no one will get back to me about posting articles

PM me if interested.
