If you use DIN valve cylinders and are planning a destination dive trip you may not be able to mount your DIN dedicated regulator on the resort or dive boat cylinders. The XS Scuba Standard Spin-On DIN to Yoke Adapter allows you to change DIN fitted regulators to fit standard yoke type tanks in seconds, without tools. This allows DIN type regulators to be used with any tank. Adapter is made from durable corrosion resistant chrome plated brass with a molded knob that is high-grip while providing a comfortable feel. The DIN to Yoke Adapter makes a great save-a-dive-kit item. Adapter fits all 200 and 300 bar DIN valves (3000 to 4350 psi).
