JBSS
Quick Connect Hoses allow you to quickly and easily connect your IDM to your regulartors without the need to unscrew connections.
Comes standard with a 32 Inch Regulator hose fitted with the Female Connection on one side and a standard LP fitting on the 1st stage side. Also in the box is the Male connection ready to screw into either the Mask or a Duel Tank Block as needed.
You can also get another Male connection to fit onto a standard Regulator so that you can swap your 2nd stage from an IDM to normal regulator. Not sure why you would want to but the functionality is there.
