Condensation on RO lines

[NL146]

My RODI unit is plumbed into the cold water line under the kitchen sink and a lot of condensation forms when I'm filling up. This leaves under the sink wet. What have you done to prevent this?

Thanks.

I checked lowes and hd but they didn't have anything in that size.

you can try slipping the 1/4" line inside 3/8" vinyl tubing, it might give it a vapor barrier.

i run 50 foot coil (1/4 ") in stand of short line, works for me, Edd idea is good to.
