oil line for garrett turbos

[A80Avant]

can someone with a pachymeter whether the oil line feed to the garrett turbos usualy sold by 034 is an -8AN size?

ID:0.44mm
OD:0.65mm

i have the line and need to buy some aeroquip fittings to modify the length.

on one side of the line it says -4 but it seems to thick to be -4AN (.22/.44mm)

thanks

edit,
my mistake as the .22/.44 is in inches so its the -4AN

anyone knows if the locking aeroquip fittings are able to sustain the 5bar of pressure? or should the oil line fitting be definitely fixed?
