Huma Externally Adjustable Regulator

Before I decided to post this topic, I searched the forum for an answer, but haven't be successful in finding one, but I apologize if somehow I missed this question being answered before.

I just purchased an externally adjustable regulator from Huma, which allows adjusting the output pressures by just turning the body of the regulator. My intention is to tether my PCP's and regulate the air so that I can get consistent shots and accuracy. My dilemma is that I have a couple SCBA 45-minute carbon fiber bottles and they both have the CGA-347 tank valve on them to which I have attached a fill station. Unfortunately the Huma regulator has female 300 DIN threads on the input (and output) Does anyone know of an adapter or a way to adapt, the CGA-347 male thread on the tank valve to the female 300 DIN connection on the Huma? I did find a new tank valve that is 300 DIN on one of the Vendor sites, but it is very expensive and since I already have the CGA-347's on both of my SCBA tanks I'm hoping that someone may know of a less expensive option.

Just in case someone else is interested in tethering their PCP using the Huma external Reg, I have found a YouTube video where a guy explains how to use it while teathered, but unfortunately he doesn't mention how he connected it to his SCBA tank. The link to the video is https://www.youtube.com/watch?v=2oRS1pttZbw&t=162s.

Thank you for taking the time to read this, Tom
 
I used these on mine

Then add quick connect Foster fitting on the end of the line to connect to the gun and use a normal CGA-347 fill station on my bottle and connect to the regulator fill line. The extra length in the set up is nice. Bottle can sit on the ground and regulator can lay on the shooting bench.

Loren,

Thank you very much! This is exactly what I was looking for. Fortunately I was able to locate the Huma adapter within the USA at Trenier Outdoors so I should receive it quicker hopefully. I really appreciate your help Bro.

Thanks,

Tom
