Difference between QD3 and QD4

Postby viperrcr » Sun Feb 03, 2013 12:55 am

I am interested in using Quick Disconnects on my new build.
I am looking to use them inline with the tubing as opposed to directly into the block via a threaded quick disconnect.

I plan to use 1/2"ID x 3/4"OD x 1/8" thick tubing with the male/female quick disconnects in the middle of the line.

I am interested in the difference between these two types: QD3 and QD4.
Specifically:
1) QD4-M13X19 along with a QD4-F13X19
2) QD3-M13X19 along with a QD3-F13X19

Seems either of these two combinations will work with my tubing, however is QD4 better than QD3? Is QD4 less flow restricted or some other performance difference?

Thanks in advance!

QD4 has a lower flow restriction if you go on those products pages go to the 3rd tab labeled files and open the first link for each product it actually shows graphs of the difference in performance.
