I’m a cool new DIN adapter. I’m slim and light, but very strong, because I’m made of 7075 aviation aluminum. I performed well under 300bar/4500psi working pressure. I am equipped with an easy-to-operate exhaust device that releases gas quickly after filling the cylinder. I also have a pressure gauge to read the cylinder pressure to avoid overfilling. Depending on your preference, I can install different pressure gauges to provide pressure readings of BAR, MPA or PSI. I’m absolutely happy to help you. Want to be more cool? Take me home!
