Written By Steven Arends

For a water-cooling loop to work, tubing is considered a crucial step, which comes in soft and hard varieties.

Don’t know what type of tubing is the best for your cooling loop?


Not to worry because, in this post, you will get to know the 7 best PC water cooling tubing for your gaming loop.

So, let’s get started.

Top 7 Best Water Cooling Tubing

For your gaming water-cooled PC, it is important to have the finest tubes possible. As, without pipes, the coolant cannot flow, and hence, your system won’t even start.

It is important to choose between the two varieties that are completely dependent on your taste.

As I have researched a lot with these pipes, I came to a conclusion that a handful of them are worth spending the money on.

And, in this post, I am going to show you the superior pipes based on their features, and type.

Sidenote, you should read about how hot can a CPU run?

Here are the best watercooling tubes:

1. Nanoxia Coolforce PETG

Nanoxia Coolforce PETG Hard tubing is designed for experienced water cooling fans who want to customize their own PC build.

This model consists of a 50 cm long PETG Hard tube which is a thermoplastic polymer. You can trim the tube if needed and can bend also. For bending purposes, you can use a heat gun.

Other than that, the outer diameter of the tube is 16mm and the inner diameter is 13mm with a length of 4×50 cm.

This tube is so uniquely firm that it is almost impossible to break. As the manufacturer says that, with this hard tube, you can comprehend the most demanding projects with slight effort and creativity without the use of any fittings or adapter.

Although this tube is good, it is still recommended to use a 13 mm CF rubber core for extra stability of the tube to ensure safe and accident free-bending. Also, you will get suitable CF1 fittings to use with the hard tubes if necessary.

Overall, I would say it’s a good deal within a small budget.

2. Thermaltake V-Tubler PETG Tube

Thermaltake V-Tubler PETG is another great deal for PC water cooling build.

This set consists of-

What I like about this tube is that:

It is extremely resistant to kinking. So, you can even get a very tight bend radius without restricting water flow which is a very desirable trait for tubing.

Another reason why I like Primoflex is that there are no prints or logos in the tube that are normally visible on some branded kits.

This pipe has a very smooth inner wall that Primoflex claims cause less junk to build upon the inside which makes it less likely for microbe growth.

If you have used the original LRT, you will notice that there was an additional antimicrobial coating, which is absent in the Advanced LRT. But still, they gave additives. So, no worries at all.

Overall, it is head and shoulders better than other tubes leaving your liquid cooling loop clean, clear, pristine, and ready for any type of coolant.

It is recommended to use a bending kit in order to bend this tube.

Overall, I would consider it a better bargain at its price.

7. Corsair CX-9059001-WW Hydro X Series

This is the cheapest Softline tube you can ever get. The Corsair CX-WW series is fully transparent showcasing your coolant on display.

It is constructed with PVC materials which are enough for tight bending inside your loop. Also, it is durable enough to flow the coolant for years.

The set has specifications of-

  • 3m long tube
  • 10 mm ID
  • 13mm OD

The only drawback to this product is that it is a very thin tube compared to other soft tubes.

However, within this budget, you won’t get a good tube like this.

Is Soft Tube Better than Hard Tube?

It depends on a user’s personal taste what type to choose.

Soft tubes are more comfortable to set up due to flexibility and it is easier to bend leading to an untidy system.

While harder tubes are capable of showcasing some amazing vision. It is difficult to bend and get it all mounted accurately.

It is recommended to use hard tubes only if you know how to handle the tube properly.

It is a very serious job to handle tubes with caution. Any small leakage can damage your entire system leading you to a great loss.

Although people prefer hard tubings over soft ones because hard tubings show some cool visionary satisfaction other than soft ones.

And in the case of performance, it’s hard to differentiate.

PC Water cooling Tubing Buyer’s Guide

A good watercooling pipe is needed to smooth the flow of the coolant through the entire loop.

You need to consider certain elements before buying one.

A water cooling system failure occurs 60-70% of the time because of bad quality tubing. And this can cause your entire system to break down in seconds.

That’s why you need to buy the perfect quality pipe for your gaming PC.

So, here are the things you should consider before buying one cooling pipe:

Bending Ratio

The bending ratio is very important for your tube. A good quality tube must bear a good bending ability.

The more this ratio, the better the quality of a pipe.

Not only that, your pipe should bear strength to handle the bent.

In this case, Primochill Advanced LRT shows user interest as this set has a good bending ratio.

Type of Tube

There are two varieties of pipes for a water-cooling loop. They are soft tubes and hard tubes.

In this post, I mentioned the type of tubing of each product. Like that, it depends on your personal interest whether to buy a soft tube lining or a hard one for your build.

Both these types are very good considering their features and advantages.

However, I would recommend using the hard tubes only if you are an expert in dealing with the bending of pipes.

Flexibility & Length

Your pipe should be long enough to fit the entire loop and also flexible enough to bear the 90 degree bends.

Some soft pipes are seen breaking apart because of less flexibility. These are bad quality pipes and don’t ever buy them. Wheres, the best quality pipes have greater flexibility and longer longevity.


Ofcourse, budget is important in case of buying anything. For pipes, your budget should be between 20$-50$. Within this range, you can buy superior linings for your custom build.

I would recommend buying a medium price range tube because, if it isn’t long-lasting enough, it can easily damage your loop.

Final Thoughts

The best water cooling tubings are those which have greater flexibility and longevity. Also, it should meet up your demands in the case of visualization too.

In your cooling loops 90% of ocular traits lie in pipes. If the pipe is transparent, you can easily see the coolant flowing through the loop giving your loop an extra appealing look.

If I were to buy a pipe, I would definitely buy the EK-DuraClear Soft Tubing because it meets all my demands.
