    Drysuit Inflator Valve Nipples

    I'm checking a drysuit out for one of my new students. It's a Mares suit and the inflator valve has an "unusual" nipple - the nipple has a single hole, so when I connect a "standard" (miflex) drysuit hose, the nipple doesn't push the schraeder valve in, so I can't inflate the suit.

    Do I need to gat a specific "Mares" drysuit hose, or would I be better off swapping the nipple to one that works with a standard hose?

    This suit has a nipple like the 3rd from left in the photo - I've only seen the other types, either with multiple holes or a bar to press the schraeder valve.

    It looks a bit like a type of CEJN connector but not the usual type that I have on my suit.

    I'd change the nipple out. What's the point of having a connector that you can't connect to with a standard hose?

    I'd simply swap it out for a different nipple - I have not seen that one, unless its the "high capacity" one used on the Mares Air Control combined octo and inflator (like the Air 2 but Mares own version) which would make some kind of sense if Mares are trying for the Apple "not compatible with anyone else" route. The Air Control comes with a special inflator hose that uses a proprietary fitting that is not compatible with anything else and is a right PITA as well as being even worse than the standard "short" octo if used in anger. The suit probably came with an inflator hose to fit which has gone AWOL somewhere

    I do not understand how there can be so many variations of such a simple, generic part

    Swap it. If you're passing it on to someone else then it just opens up a load of hassle for them to have an oddball hose.

    Assuming they haven't also put an odd thread that no-one else uses on the nipple as well.

    Our club BCD's have three different fittings for direct feeds. One hose will fit jackets A&B and another will fit Jackets B&C but none will work with all three although they will connect to all of them.It is all to do with the length of the piston in the Schraeder valve. On some, it is too long and continually inflates while others are too short and will not inflate!

    I was in the process of swapping it, when I realised that it works differently to what I'm used to. There's a plastic rod up the middle of the nipple, so when the valve is squeezed, it pushes the rod onto the shraeder valve. It works perfectly with a standard miflex hose. (the plastic rod is like the green bit in the photo above)

    All the drysuit inflators I've come across before have a nipple that pushed the shraeder valve pin, then the button opens a valve inside the valve body.

    The CEJN fittings don't have a spigot in the midddle, they push the valve back over a wider area. I've got a CEJN fiiting on my drysuit since I finfd them much easier to connect and disconnect under presure. I suffer from Reynauds in cold water and anything that helps manual dexterity is welcome.

    One thing I have seen a few times with the CEJN is the central cap in the centre of the hose fitting being dislodged leading to a freeflow from the fitting. If the person connecting the hose was not experienced and let go the hose can then whip around the head.
