Hey Gang! 
Hope all have been well…a Happy and Healthy New Year to all!
My sister was nice enough to gift me a new IC…she got me the 3/8" with the hose fitting on one end (#7869), but I want to hook up the loose end to my circulation pump and need to get the right fitting…what is the Inside Dimension of the vinyl tubing?
Thx!
Should be 3/8"
No the copper is 3/8" ID and thus 1/2" OD. The tubing would have to be 1/2".
Thanks Deadeye…that’s what I was looking for…I knew the copper was 3/8" ID so the vinyl would have to be slightly bigger (to match the copper’s OD).
:cheers:
Mine would leak when I would run the water wide open,
No matter how snug the clamps were.
I soldered a pair of barb fittings onto the ends and its worked great ever since.
Something to think about.
And the award goes to greg! 
As it turns out, I inserted some 3/8" OD tubing that fit snugly into the IC’s tubing…so the IC’s vinyl tubing ID is 3/8" …
Hope this helps someone…
