CGA870 (Med Block) to 1/4'' NPT

            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.
