★【2.3LDiving Tank Package】The D23-A incorporates improvements to the diving package, including bottle head first stage valves and pressure gauges, as well as pressure tubes,and added some configurations to enhance the diving experience.The total weight of D23-A diving package is 4.6kg. It can be carried directly for short distances, and can be transported in the car if traveling..
★【Bottle top valve】: The main material of D23-A bottle top valve is brass chrome plating, using vacuum color plating process, to improve the anti-seawater corrosion performance, and more beautiful appearance. The bottle valve has a low pressure interface, which can be connected to BCD or life jacket for better applicability. The air inlet adopts high precision filter core, which can filter particles over 5 microns. The scuba tank is stamped with the DOT certification mark, you can always check..
★【Pressure gauge and pressure tube】: D23-A scuba tank uses A more stable pressure tube, which is made of PVC and butadiol mixture material. It can bear A maximum pressure of 10MPa, and the internal pressure is only 0.8-1.2mpa in normal use. In order to make it easier to check the remaining air in the tank during the dive, we use an extended tube connection pressure g....
