Inexpensive yoke

I bought a scuba yoke, k valve to din, they had several 25 to 35 dollars. Since I knew I would be using it when I filled two scuba tanks, switching them over removing installing multiple times etc, I opted for the one made of stainless steel, threads looked much better hopefully higher pressure rating and stronger, engraved 232 bar and i think 361 stainless steel material). I paid 50 but I erred on the side of safety. Pay the extra for safety.
