parts express sells the precision product too. I had my first experience with them this weekend. Nice to be able to assemble the port and THEN insert them in the box.

15.47in length.

Would they be measured from flare to flare or before it flares?

Yea $14 each is pretty expensive..

4" flares account fo 3" of length each. Therefore, if you need 15.5" total length... then then actual length of the tube needs to be 9.5"

depending on the flares. precision ports yes but I have some flares that seem to only be 2" of total flare, but they are not long enough.
