Does anyone know of an alternate screw-on hose fitting for platypus bottles. Specifically, it would be used for a inline gravity filter setup with a Sawyer filter. I know that platypus used to make a hose fitting that has been discontinued and I believe the only way to get them now is to buy the whole kit. Since I already have the bladders, hoses, and filters all I need is a way to connect them.

Here is what I know about the platypus caps:

- 28mm (same size as many screw top drink bottles)
- Fittings were originally made by Colder Products Company as a custom product. I emailed them and the response confirmed that but offered no specifics as to current retailers.


I am looking for something that would screw on to a platypus bottle then couple with the standard(?) .25" hosing.

Maybe something like this, but I have not been able to find them in the correct size:

Alliteratively, I did try to make one out of a used soda cap bottle and a loose barb fitting, and while it works at home I would not trust its durability on the trail when my water supply depends on it.
Any suggestions? Thanks.

Ken -- Thank you for the link. (I will use the post office delivery. The home delivery looks a little steep).

That makes it easy for me. I'm sure there is a creative solution out there, but since there is still a supply and the price is so good I even ordered a couple extra.

Glad to help. Paul is a good guy to deal with.

Try this. Pull the bite valve off, which leaves you with a hard plastic stem that you can attach your tubing to. The nice thing is that the hard stem rotates to open/close the outlet.
