I decided to go G1/4 QD + extension, so that i use my current 11mm ID fittings. And then i know the tube will also be fine as it was years now.
A couple questions before the shopping basket is complete:
1) What is the difference between this
QD3 male and this
one? The latter has a hexagon close to its G1/4.
The first one is a male QD with a male (outer) G 1/4 thread
on the other side (QD3-MSG4-BK
). The second one (QD3-MSFG4-P-BK
) is a male QD with a female (inner) G 1/4 thread
on the other side, also with an additional outer ring so you can panel mount it. This is what I was talking about in my last post when I said one of them should be a female G1/4. That means you can screw your fitting directly into it and do not need an extension.
Sometimes a picture explains better than words, so here is the picture from Koolance's product page that shows the female G 1/4 and the panel threads better. This is for the silver version since they don't have a corresponding picture for the black one.
The panel mount is unnecessary for your application but over all it might look better and take up less space than if you added an adapter to the male G 1/4 version (QD3-MSG4-BK). Koolance also makes a QD fitting without the panel mount (QD3-MFG4
), but only in silver.
2) Regarding the extensions, i think a 15
mm would be enough for it to connect the QD and the fitting. I think 15 or the 20mm will be enough, I have to measure the lengths.
As I said above, if you get the QD3-MSFG4-P-BK you do not need adapters or extenders, you can screw your own fitting right into the QD.
If you did get the QD3-MSG4-BK which has the male G 1/4 thread, those extenders you gave the links for are the wrong kind as they are all Male-Female G 1/4 extenders. Instead, you would need to get Female-Female G 1/4 extenders (also sometimes called connectors or adapters) in order to screw your own fitting in.
3) Do i need extra O-rings for the extension?
No. They will come with O-rings.Edited by threephi - 3/10/14 at 11:58am
