CGA870 (Med Block) Tank to ¼” NPT
This is a CGA870 Bi Pin Adapter. This adapter mimics the tank valve found on emergency O2 Tanks. This is commonly used with a din or a CGA540 to convert these tanks to accept medical regs. This way the diver can take advantage of the extra oxygen on site in case of emergencies. The connection is ¼” female NPT.
