Catheter question

I've always been a ziplock man myself but the recent thread got me
considering catheters.

My ship has a fitting for connecting a catheter. The fitting is connected
to a tube that ends at the trailing edge of one of the gear doors. The
fitting has a rubber O-ring and looks like another fitting on the tube
leading from the condom-like part of the catheter should just snap onto it.

I went Googling male external catheters and found pic of most of the parts
(condom thing, leg bag, valve btwn condom & leg bag), but no descriptions or
images of the connectors. Given my ships layout, there's no place to put
the leg bag that wouldn't be uphill. Any words of wisdom from catheter
users? Are they all made w/quick connects to the bags? Should I just buy a
box of the condoms and the bag and use the tubing to re-plumb the ship?
