Joel,
I agree with Steve on this. Any possibility of adding a needle valve?
We normally will not make modifications to and existing product that we source. I can look into it for another production run but it wont be soon.
That said. The transfilling process is so short and simple a specific needle valve is really not necessary. Unless the one doing the transfilling is such a boob that they don't understand large volume to small volume filling these transfill hoses are virtually fool-proof.
What I will normally do in the transfill process is this.
1. Know Supply pressure
2. Know Target Cylinder existing pressure
3. Attach transfill hose with gauge at target cylinder side.
4. Open target cylinder slow and then ALL the way open. (verify pressure)
5. Open supply cylinder slowly and watch target gauge.
6. When target reaches goal turn off supply, let settle then add supply as needed to reach final target if possible.
When we are done we put a label on the supply cylinders of what the remaining pressure is.
It's pretty simple process.
Cheers
