This set comes with Sysprep additives that are to be used to your liquid before firing up the loop.

What I like about this tube is that it’s 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.


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

  • »Acrylic tubings are less resistant to force

Why We Picked It

The Corsair Hydro X Series XT Hardline is the best hard tube that focuses on aesthetics.

The high-quality, straight-line tubing uses PMMA or acrylic material. Though acrylic tubings are inferior to PETG ones for durability, they do a great job of putting your water-cooling fluid on display with their crystal-clear PMMA material.

Now coming to this tubing from Corsair Hydro X series, it has a thicker wall than regular acrylic tubings. The resilient construction makes the pipe last longer under high pressure and high coolant temperature.

The thicker wall makes it difficult and time-consuming to bend the tubes. It takes a lot of patience to work with these tubings.

But once done, you’d be glad with the results as these offer the most visually appealing water cooling loop, thanks to the clarity of the body.

The Bykski Rigid Acrylic Tube is a great bargain at its price as a hard tubing that’s easy to install.

How We Chose the Best Water Cooling Tubing for PC

A good water cooling pipe is needed to smoothly flow the coolant through the entire loop.

Failure while water cooling a PC 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. There are many factors to consider before buying tubing.

Here are the things you should consider before buying PC liquid cooling tubes:

Type of Tube

There are two types of tubes for water-cooling loops: soft tubes and hard tubes.

Soft tubes are easier to bend, and install but can become cloudy and clutter the inside of your PC case. Rigid tubings are difficult to cut, and install but are generally more transparent, durable, and provide a clean look.

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

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

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.

We look at the bending ratio of the tubings and conclude if they are good enough or not.


The material of the tube is an important factor to consider. Soft tubes typically use PVC. Hard tubes generally use PETG or PMMA (acrylic).

Acrylic tubes are more rigid but less resistant to force. PETG tubes can absorb force better than acrylic ones, which makes them more durable.

We check the material of each tubing and mention the use case.


Transparency is quite important if you want to show off the coolant inside the loop. Soft tubes tend to get cloudy over time, while acrylic tubes are the most transparent with a clear view, making them ideal for aesthetics.

We take into account the transparency of each tube after some use and to what extent they can show the true colors of the coolant.


Of course, budget is important in case of buying anything. It’s important to not cheap out on the tubings as a bad quality product can ruin your expensive PC in no time.

Is Soft Tube Better than Hard Tube?

It depends on a user’s personal taste or preference on whether to choose a soft tube or a hard tube. Both have their pros and cons.

Soft tubes are more comfortable to set up due to flexibility and it is easier to bend. However, since they’re flexible tubings, it can lead to an untidy system.

Harder tubes are more time-consuming and more involving to bend, cut and install, but you can get some seriously good results from them. Since hard tubes are rigid, you can bend them at right angles and achieve a clean look.

Soft tubes also have a tendency to get cloudy and blurry over time, while many hard tubes (especially acrylic ones) can provide clear and almost transparent visuals.

It is recommended to use hard tubes only if you know how to handle the tube properly. Otherwise, it is recommended to stick with the soft tubes as they’re more beginner-friendly.

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 over soft ones.

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. If the pipe is transparent, you can easily see the coolant flowing through the loop giving your PC an appealing look.
