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- Fittings were originally made by Colder Products Company as a custom product.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.
