fittings size

[Amit132]

Hey,

I build two years ago my custom water cooling system, and I used then 19/13mm tubing and fittings.

I want to change my system but I can't find selection of tubes or fittings in this size.

All I can do is to replace all the tubes and fittings(Or buy from the very little selction there is of components in this size)?

I tried to convert this size to inches but it is seemed that there is no exactly matched size in inces

are you sure its not 16/12? thats a much more common size.

19/13  appears to convert to  3/4 od/1/2 id (inches)

Will it be exactly the same? cause 13mm = 0.512", so they are not really equal

and I'm afraid this gap will cause leaks

the difference is .5mm and the clamp (zip tie/ snake clamp/ whatever you use to hold the tube on)   is what causes the seal to happen.   if you use compression fittings, its the part you slide over the tube then screw into the base that  makes a seal  as you tighten the fitting.

 

I personally run my pumps jumped (only powering pumps)  when i do a significant re-arrangement or addition to my loop.   that way i can  test  joins   (with pumps in full force) to  see if they leak before  i power on the entire system.

 

THIS is a step i recommend to never skip. as it only takes one loose/leaking fitting  (they may hold fluid until the pumps create the PSI in the system while operating)  and then it becomes an emergency full stop.
