1. EKWB EK-Tube ZMT tube 16/11 mm
With the EK-Tube ZMT, the Slovenian traditional manufacturer EK Water Blocks presents its own water cooling hose, designed according to its vision of perfect tubing that brilliantly meets the special requirements of a durable, high-performance water cooling system. "ZMT" stands for "Zero Maintenance Tubing," meaning it requires absolutely no maintenance. The EK-Tube, offered here with a diameter of 16/11 mm, is a stylish matte black hose made of EPDM rubber, providing high industrial quality.
This hose is manufactured by EK Water Blocks to withstand the toughest conditions over long periods, comparable only to neoprene hoses. It offers an outstanding lifespan, even when exposed to UV, ozone, or heat for several years.
Unlike plastic products made from PVC or PUR, the EPDM rubber of the EK-Tube ZMT does not pose the risk of plasticizers being leached out over time, which can clog the water cooling circuit and reduce effective cooling performance. Additionally, the EPDM rubber used here allows for very tight bending radii due to its elasticity and stability. The hose offered here is black and has an outer diameter of 16 mm and an inner diameter of 11 mm.
Note: This is a 3-meter long hose piece delivered in retail packaging.

3. EKWB EK-Pro Tubing 17/10mm, Reinforced, EPDM, Preformed 45° /90° - black
The EK-Pro Tubing 10/17mm Reinforced EPDM Preformed 45°/90° - Black+ is a type of reinforced tubing specifically designed for use in computer water cooling systems.
This tubing features an inner diameter of 10 mm and an outer diameter of 17 mm. The reinforcement with EPDM (Ethylene Propylene Diene Monomer) makes it more resistant to bends and kinks compared to conventional tubing. Additionally, it is available in preformed 45-degree and 90-degree angles, which facilitates installation in complex water cooling systems.
The black color is popular for its aesthetic appeal and can complement other components in a PC well. Such reinforced tubing is typically durable and provides reliable performance for water cooling solutions, helping to regulate the temperature of high-performance PC components like processors or graphics cards.
Technical details:
- Color: Black
- Material: EPDM
- Length: 100 cm
- Outer diameter: 17 mm
- Inner diameter: 10 mm
- Delivery includes: EK Water Blocks EK-Pro Tubing 12/6 mm Reinforced EPDM 1 m - black
Note: Use only with clear, transparent cooling liquids. The particles and additives in pastel liquids can clog and permanently damage water cooling products such as radiators, pumps, coolers, and tubing. This may also void the manufacturer's warranty.

4. EKWB EK Tube ZMT Hose 16/10 mm
With the EK-Tube ZMT, the Slovenian traditional manufacturer EK Water Blocks presents its own water cooling hose, designed according to its vision of perfect tubing, which brilliantly meets the special requirements of a durable, high-performance water cooling system. "ZMT" stands for "Zero Maintenance Tubing," meaning it requires absolutely no maintenance. The EK-Tube, offered here with a diameter of 15.9/9.5 mm, is a stylish matte black hose made of EPDM rubber, providing high industrial quality. Despite its smaller diameter, the hose is compatible with 16/10 compression fittings.
This hose is manufactured by EK Water Blocks to withstand the harshest conditions over long periods, similar to what neoprene hoses can achieve. It offers outstanding longevity, even when exposed to UV, ozone, or heat for several years.
Unlike plastic products made from PVC or PUR, the EPDM rubber of the EK-Tube ZMT poses no risk of plasticizers being leached out over time, which could clog the water cooling circuit and reduce effective cooling performance. Furthermore, the EPDM rubber used here allows for very tight bending radii thanks to its elasticity and stability. The hose offered here is black and has an outer diameter of 15.9 mm and an inner diameter of 9.5 mm.
Note: The hose is delivered exclusively as a complete piece, with the ordered quantity corresponding to the total length in meters. So, if you order 1 piece, you will receive 1 m of hose; if you order 2 pieces, you will receive 2 m of hose, and so on.
Technical details:
- Diameter (outer/inner): 15.9/9.5 mm
- Length: 1 m (more depending on the quantity ordered)

7. EKWB EK-HD Tube 12/10mm 4-Slot - two pieces
The EK-HD Tubes are two cut-to-size tubes made of solid acrylic for connecting multiple VGA water blocks. In combination with EK-HD adapter fittings, this EK-HD tube set can be used as an alternative solution for connecting several full-cover GPU water blocks (SLI/CrossFireX). The EK-HD tubes are designed for use with PCI-Express slots (81.3 mm distance between the two PCI slots).
Each tube has an inner diameter of 10 mm, while the outer diameter is 12 mm. They are each 61.3 mm long.
Important: These cut-to-size tubes are only suitable for SLI/CrossFireX connections of modern EK Water Blocks full covers that use an EK-FC terminal. For other versions (CSQ, pre-CSQ) of water blocks, longer tubes must be purchased and cut to size by the user. It is essential to slightly sand down sharp edges on the tubes to avoid damaging the sealing rings.

8. EKWB EK-HD Tube D.I.Y. Kit 10 & 12mm
This EK-HD Tube D.I.Y Kit from EK Water Blocks is specifically designed for clean and precise cutting of acrylic tubes with an inner diameter of 10 to 12 mm. The set includes a saw, a 230 x 280 mm piece of sandpaper, and two silicone cords.
Using a heat gun along with the included silicone cords makes it easy to cut the solid acrylic tubes yourself. Afterward, you can smooth the ends of the acrylic tubes with the provided sandpaper.
