Does anyone know where a person could get a spark arrestor or maybe called a one way check valve that would be in a gas line like hydrogen gas that would prevent any sparks from going backwards into the system?

Whatcha' making?

I've been looking for the same item for years.....

Isn't something like that available for oxy / acetylene torches?

Yes. Go to your local welding supply store, they will have them in many different sizes.

this has been on my mind and here is an excellent write-up on a possible solution.
