I'm rigging together a sawyer mini based filtration system with a platypus carbon element. Anyone have a cheap source for lightweight tubing that fits those pieces?
Thanks!

I think, but I'm not sure, that the "standard" water filter tubing is 1/4" inner diameter with 1/16" wall thickness.
For my Sawyer gravity setup, I used food safe 3/16" inner diameter tubing with 1/32" wall thickness, from amazon. It's a bit difficult to fit over the 1/4" barbs on the filter. But, the space savings over the standard tubing is significant, and it seems to still work fine.
Lots of food safe tubing available at your local brewing store…if it's good for beer it's good for water :)
FWIW, the weight added by my conversion (consisting of 2 sets of the Sawyer SP110 adapters, the Platypus carbon filter and tubing) comes in just at 3 oz
You need ~2.5' of tubing total, so not real sure how much weight there is to lose there.
