Fittings Help

[Pipit213]

I saw on the xspc raystorm 750 rx360 kit that the barbs are G1/4" to 1/2" but the hose 7/16". If I wanted to get compression fittings what size would I get? I am new to watercooling and simple answers would be nice

The FAQ and 101 stickies at the top of this forum section answer your question completely and in a lot of detail.

I saw that but can you explain different barb sizes with different hose?

ID = Inner Diameter

OD - Outer Diameter

 

When you see a fitting or tubing it will say ##ID  ##OD

 

The inner diameter will obviously always be smaller than the outer diameter.

 

With fittings it will also say G1/4. This is  the thread size on the fitting and it is a standard in most water-cooling components.

 

For barbs they have no OD measurement because nothing goes on the outside of the tube.

 

 

 

What all this means is that you simply want the dimensions of your tubing to maths the dimensions of your fittings.

 

There is no real performance difference between different diameters.

 

The thicker the walls of the tubing are the less likely it is to kink.

 

Two popular sizes are 3/8ID 1/2OD and 1/2ID 3/4OD. The benefit of them being popular is they have more fittings and fittings tend to be cheaper for them.

thank you this is what i needed

a lot of users use 7/16" on 1/2" barbs so not to use clamps. it makes for a tight and

leak-free seal. but the cuts have got to be straight and clean.

 

other than that, you'd use the id for id and od for od measurements exactly for a

compression fitting, if not you have issues and leaks..
