This tool opens and closes the Mares AST anti-infiltration technology for DIN first-stage connections.
The tool has a stainless steel handle for opening and closing by hand.
 
With a heavily corroded AST system, it is possible to use a 14mm Open end spanner, Socket, or Adjustable spanner wrench. The emphasis here is on the opening.
Closing this fragile piece of technology must be done by hand to prevent damage.
 
The Mares DIN regulator AST scuba tool is precision machined from stainless steel.
