Hi all,

I got a situation where I need Capillary tubes of size: 0.094'' ID 15.75'' Lenght. Problem is, the manufacturer I deal with doesn't have this ID and could be three months before he can send me some.

I could get some 0.079 ID Cap tubes ( Closest I got on hand ) & I heard there were charts that could help me determine the right lenght to use. Where can I find those ?

It would be for R-22 @ 30 000BTU/Hr , 1 outdoor unit & 3 Indoor , Inverter Compressor. Do I have to get the same exact Capillaries or can I calculate equivalency with those 0.079 ID ones ?

I made the rule of three but really think it must be harder than that to find the equivalency.
Here's what it looks like..:

0.079 divided by 0.094 = 0.8404255
0.8404255 times 15.75 = 13.236701

So I would use a 13 7/16'' Lenght.

Waiting for your Expert advises

Thanks,
Nice site BTW !
