Tubing EK Water Blocks Transparent PVC

The EK Water Blocks 3831109895962 Transparent PVC tubing is a clear soft tube designed for PC liquid cooling loops. Manufactured to provide high optical clarity and reliable fluid flow, this 10/13 mm tubing balances flexibility with dimensional stability. It is suitable for visible custom water cooling builds where coolant appearance and line routing matter, and it is engineered to resist common causes of discoloration and degradation.

Advantages

This transparent PVC tubing offers exceptional clarity for a clean system look while allowing compatibility with UV-A and UV-B reactive coolants. It is formulated to resist UV-C exposure, reducing the risk of coolant deterioration and color change caused by sunlight. The tube uses a non-phthalate plasticizer and materials sanctioned for food-contact applications and compliant with USP Class VI standards, improving resistance to leaching and chemical degradation. Its soft construction provides ease of bending and routing inside tight cases without compromising flow performance.

Suitable for

• Custom PC water cooling loops with 10 mm inner and 13 mm outer diameter fittings
• Visible builds where tubing clarity and coolant color are important
• Environments requiring UV-A and UV-B reactive coolant compatibility
• Systems where reduced leaching and long-term coolant stability are desired

Key specifications

• Material: Transparent PVC (soft tubing)
• Inner diameter: 10 mm
• Outer diameter: 13 mm
• Length: 3 m
• High optical clarity with UV-A and UV-B transmissibility
• Low UV-C transmissibility to reduce coolant degradation
• Non-phthalate plasticizer and components meeting food-contact and USP Class VI criteria
• Resistant to degradation from Beta, UV and Gamma rays

How to use

Cut the tubing to the required lengths with a sharp tube cutter to ensure square ends and smooth connections. Slide the tubing over compression fittings or barbs compatible with 10/13 mm tubing and secure as recommended by the fitting manufacturer. When routing inside a case, avoid kinks by using gentle curves or angled fittings; support long runs to prevent sagging. Flush the loop with appropriate cleaning fluid before first use and again after installation to remove any debris. Fill the loop with compatible coolant and run the pump at low speed initially while checking for leaks.

Recommendations

For best long-term appearance and performance, avoid direct prolonged exposure to strong sunlight and use coolants that are compatible with PVC tubing. Periodically inspect the tubing and coolant for signs of discoloration or deposits and perform scheduled coolant changes according to the coolant manufacturer’s guidance.
