4) Screw on o-ring sealed dust caps for your Din connections . No water will get in the H.P. whip so you can take off the heavy bottles when your cleaning your kit. Also notice the little lanyard to pull on to disconnect your tanks.
Not sure why I was reading this thread as I'm a Kiss diver, but nice set of photos!
One word of warning re the dust caps: I got some which look just like yours (from Beaver I think), they have an O-ring inside and look like they will seal. I got back from a trip where I'd hired cylinders, screwed the dust caps on my 1st stages, and chucked the unit in my rinse tank for a few hours with the rest of it sealed up. Result 1 flooded 1st stage! The ones I have do NOT make a seal

As you have an O-ring on the 1st stage you want a nice flat mating surface in the cap with a centre depression to make a good seal.
