EK® is releasing new Hard Tubing Series kits
EK® Water Blocks, the premium liquid cooling gear manufacturer, is introducing its newest line of popular EK Kits, the Hard Tubing kits. These kits are a great choice for enthusiasts who are looking for a complete high-performance hard tubing liquid cooling solution.
EK-KIT HT240 and EK-KIT HT360 beside the super compatible thin EK-CoolStream SE radiator that they use will also be very suitable for low noise scenarios. As we know, slim radiators benefit from low-speed fans more than the thick ones, and the 120mm fan format only adds additional cooling surface.
Why did we design the Hard Tubing kits?
The EK-KIT HT240 and HT360 are complete hard tubing liquid cooling kits dedicated to users who seek top performing market proven components with versatile case compatibility in focus. Designed for cases with limited radiator space in mind, the HT kit is a great choice for liquid cooling enthusiasts who are looking for a complete high-performance hard tubing cooling solution. This kit brings everything you need to assemble your custom liquid cooling loop. You don’t have to worry about compatibility issues or matching the fitting and tubing size. If you are looking for a quick access to the world of premium liquid cooling, this is your entry ticket. The end result is a beautiful looking hard tubing liquid cooling loop that is also ready for a future upgrade.
EK-KIT HT240 and EK-KIT HT360 bring the following components:
EK-Supremacy MX UNI – a CPU water block that fits all modern CPU sockets like Intel® LGA 115*, Intel® LGA 20** and AMD® AM4 with a universal mounting mechanism that offers error-preventing, tool-less installation. The result is an easy installation which brings perfect performance every time.


EK-Supremacy MX UNI
EK-CoolStream SE radiator (EK-CoolStream SE 240 and EK-CoolStream SE 360) – offers best cooling capacity in the sub 30mm thick radiator class: copper fins provide massive surface area while the parallel flow cooling chambers reduce hydraulic flow resistance to a minimum. Built for EK-Vardar 120mm high static pressure fans, these radiators are optimized for maximum heat dissipation across an entire fan operational range, thus delivering exceptional performance at both low- and high airflow operation.
EK-CoolStream SE 240 and EK-CoolStream SE 360
EK-Vardar F3-120 (1850rpm) – industrial grade high-static pressure computer cooling fan, designed and built primarily for high-performance computer liquid cooling systems. EK-Vardar is simply the best choice for computer radiator cooling as it provides unmatched performance throughout the entire operating range. Two 120mm Vardar fans are included with EK-KIT HT240 and three 120mm Vardar fans are included with EK-KIT HT360.

EK-XRES 100 SPC MX PWM (incl. pump) – is a value-oriented water cooling pump reservoir combo. Co-engineered by EK Water Blocks, it has been designed to lower the production costs yet still offer premium hydraulic performance at the best price. PWM control allows for automatic pump speed regulation depending on your CPU temperature. Full performance on demand or whisper quiet operation in idle mode!

EK-HDC Fitting 12mm G1/4 – Black – is a hard tube compression fitting which also responsible for the name of this kit. Designed for use with solid tubing, the EK-HDC Fitting prevents the hard tube to be pulled out of the fitting by compressing the rubber gasket underneath the ring. The barb is made of nickel plated CNC machined brass while the locking ring is made of black-chrome plated CNC machined brass. Best practice is to gently secure these fittings using the enclosed Allen Key 9mm.

EK-AF Angled 90° G1/4 Black – EK-AF (Adapter Fitting) is a revolvable angled adaptor (90°) with G1/4″ threads. The adapter allows the connection of liquid cooling components and fittings with G1/4″ threads to simplify the tubing routing possibilities in your cooling loop.

EK-CryoFuel Clear – is a specially designed additive for computer liquid cooling systems. It comes in a weight-saving 100mL concentrated form, which just needs to be diluted with 900mL distilled water (not included). The diluted liquid forms a stable non-toxic mixture for your liquid cooling loops and contains all the necessary corrosion, scale, and biological growth inhibitors.
EK-CryoFuel Clear Concentrate (100mL; for 1L of coolant)
EK-HD Tube 10/12mm – a total of 2 meters of acrylic hard tubing with timeless clarity. EK-HD Tube is solid type extruded acrylic tubing intended for use with the included EK-HDC series compression fittings. The tubing has to be heat treated to achieve desired bends and shapes.
The best solution for a quick and simple start!
The majority of components are pre-assembled, resulting in a quick and painless installation procedure. Once installed, these kits are a full custom loop solution. They can be upgraded with additional water blocks, for example, GPU water blocks and components, such as additional radiators. If you are cooling your rig with air and dreaming about liquid cooling, these kits will make your transition to this elite club as easy as possible!
For a successful installation of the kit, EK recommends the purchase of the EK-HD Tube D.I.Y. Kit 10&12mm and EK-HD Tube Reamer tools. If you are building your first hard tube based loop, EK recommends that you purchase additional EK-HD Tube 10/12mm tubing since hard tube bending can be a trial and error based task. For easier tube routing and more sleek aesthetics, EK EK recommends that you purchase additional angled adapter fittings.
