Alternative to Tornado Tube Connector Between BeFree and Platypus

I recently lost my water filter system. It consisted of a Hydrapack (dirty water) bladder, a BeFree filter, a Platypus (clean) bladder along with a Tornado Tube. It has two basic modes. If I’m hiking and want a quick drink I will just drink from the filter output. But if I have time, I will attach everything, hang it up and then just drink from the Platypus. Unlike a system using tubes, the whole thing can be dangling from a branch (the clean bladder doesn’t have to sit on the ground). I like the wide mouth of the Hydrapack and the quick (initial) performance of the BeFree.

The problem is the threads don’t quite work. The Tornado Tube is designed to be attached to soda pop bottles. The threads don’t quite match the Platypus bladder but I can make it work reasonably well. But since I switch back in forth it isn’t ideal. It sometimes gets jammed and doesn’t come off easily. Does anyone know of an alternative connector that might work better?

I am also considering the Platypus QuickDraw Filter. Based on the reviews I’ve read it has a similar initial flow as the BeFree but is a little better in the long run (although not as good as the Sawyer Squeeze in that regard). Any experience with using the QuickDraw to filter into a Platypus would be appreciated. Of course I would need a different dirty water bladder (I would probably get the Cnoc).

I’ve screwed sawyer squeeze onto a platypus bag but the thread pitch is slightly different.  Since it’s plastic and not too many threads it sort of works, the plastic deforms (elastically).  But it doesn’t seal perfectly, water leaks a little.

( Engineer joke about plastic deforming elastically, not plastically)

Yeah Jerry, that’s the problem. You can make it work but because you are putting pressure on the threads it can get stuck (or not fit tight enough).

As an FYI, if you are using it as a gravity feed, you will get better flow with a tube to increase the pressure head. Of course, if you’re happy with it as-is, there’s no need to carry something extra.

yeah, tube for better flow.

I just screwed my squeeze onto the mis-matched platypus and turned it upside down.  Low flow, but it eventually produced the desired amount of water.

But then it was so slow that I got distracted.  Came back and the output bottle filled and a bunch overflowed onto the ground.  Which was fine, I had plenty of water, but it’s poor form.

I just squeeze it now, easier.

I’ve used both and have switched from my trusty hydro blue over to the quickdraw permanently. Flow in my experience is better than a be free and it’s also back flushable. It’s criminal that Katadin made the 28 mm threads on the Befree non standard on purpose.

I just wish that platypus would simplify the quick draw system and make 28 mm standard dreads on both sides without attachments. Only issue I have with the system is that there are too many bips, o-rings and caps to track.

28mm or death for me.

Thanks for the responses.

I ended up buying the Platypus filter and a Cnoc water bag for dirty water. I only tested it in the bathtub but the flow is outstanding. The connection to the clean Platypus is easy and snug. I had extra water in the Cnoc but no drips. I like the big opening for the Cnoc although it will take a bit of getting used to. If I don’t like it I can always go back to using Hyrdapack for dirty water (since the filter handles both). I probably won’t but this is an option I figure is worth mentioning (especially if you are transitioning from BeFree filter and didn’t lose the dirty bag at the same time).
