Praxair does supply fittings. We have service contract for filling Helium but when Dewar comes it always has fitting. Check with Praxair.

Subject: AMMRL: Summary of Helium Dewar Fittings Responses
Some added information, the Liquid Helium Supplier does not supply fittings for the Dewar, we must provide our own as they do not even know where to get them. Below is a summary of response, multiple responses of the same answer are only listed once. Thank you all for your help, I believe that they were able to find some fittings, but I have not talked to them again yet.
-You might want to check with MR Resources. Years ago, I was able to get a set of fittings (3 or 4 pieces) from them. The largest adapter fits the 250L Helium Dewar.
-Normally the company that delivers the Helium will add these fittings and extra O-rings on the tank.
Some companies don't do it, but they may be able to provide them when asked
