FX Female Foster quick connect

Some hose ends with 1/8" NPT. If the connector on the your air hose use 1/8" NPT then you can use 1/8 NPT female to 1/8 BSP female adapter to connect the FX female Foster quick disconnect. Not many place have that coupler. I looked for the same thing when I first got my tank and hose setup.
