This is my first attempt at making a fill whip. I am sure there will be changes to it in the future (I already know of a couple I'd like to make) The reason I call this my "vesatile" fill whip is because everything is connected using straight pipe quick disconnects allowing me to change the configuration of the pieces to easily suit a variety of purposes. Gauges can be changed to give a more precise focus on a larger gauge, or one of the DIN adapters can be connected to a gauge to make a handy tank pressure checker. It can change in seconds from an Oxygen whip to Helium, Argon or a simple transfill whip between SCUBA tanks. In the future I would consider going with hand tightening fittings and a second bleeder valve.

WARNING: The connections pictured here are low pressure fittings (notice the square edges) I DO NOT recommend using them - you NEED to get high pressure fittings -that's my next change to this fill whip.
