1/4" NPT Female to 3/8 O-Ring

¼” NPT Female to 3/8 O-Ring   This adapter has ¼” npt Female on the one side and 3/8” o-ring on the other.  This 3/8” o-ring on this one is the same as your scuba regulator.  This allows you to screw this into your scuba regulator and take full advantage of any ¼” npt accessory.  This adapter will allow you to make a long hose for hookah; a cleanout for your sprinklers; you name it.  Better yet, as I said earlier, convert it to quick connect and make a million different adapters.
