to follow here is a photo I uploaded shows the issue:

Yes you got it right, I cannot screw 2 of the adapters into the MPS unit because the ports are too close to each other, im using it for pressure drop and im trying to link it directly to the hardline loop without the hose.
If the M5 to G1/8 fittings are too large, you will have a bigger problem getting two G1/8 to G1/4 next to each other. This, and flow rate not being an issue, is probably why they went to the smaller fittings.
You may have to use the
6mm HOSE to run between the MPS
FITTING you linked, and this
FITTING screwed into a
G1/4 T-BLOCK in the hard line run.
in terms of the o-ring there are different outer diameter sizes as well (8mm/9mm), any idea which is relevant ?
I presume FKM is better than nitrile rubber because it lasts longer
This is probably a moot point as you most likely will not be able to use this fitting, but the outer diameter depends on the thickness of the O-ring. With a 5mm ID, and 1.5mm thick O-ring, the OD will be 8mm. For a 5mm ID with a 2mm thick O-ring, the OD will be 9mm.
The required thickness depends on the length of the 5mm male connection, how far down the thread goes on the 5mm connection, and the depths of the 5mm tap in the MPS sensor.
