As a first timer for custom water cooling , decide on which type of petg tube and the size to get first
For fittings, the size of the thread is also indicated in inches.
The thread is indicated with a G in front.
The most popular thread size is G1 / 4 ".
then consider Example:
If you order a 1/2 " OD tubing , then you will have to get a fittings with an inner diameter of 1/2" (13 millimeters).
The three most popular tubes ID are:
1) 1/2 "(13mm inner diameter)
2) 3/8 "(10mm inner diameter)
3) 5/16 "(8mm inner diameter)
Example nos.2
if you order 1/2 "(13mm ID) hose, you must order 1/2" (13mm OD) fittings!
likewise order 3/8 "(10mm ID) hose, order 3/8" (10mm OD) fittings!
