Trubica EK Water Blocks EK-Tube ZMT

The EK-Tube ZMT is a high-quality black tubing engineered for custom liquid cooling loops. Made from materials selected for flexibility and durability, this tubing resists kinking and maintains consistent inner diameter under bending stress. Its smooth inner surface supports steady coolant flow while the matte black exterior provides a discrete appearance inside PC cases. The EK-Tube ZMT is compatible with common push-fit and compression fittings and is intended for use in PC water cooling systems where reliable flow and neat routing are required.

Advantages

EK-Tube ZMT combines flexible construction with dimensional stability to simplify installation and routing in compact builds. The tubing’s resistance to kinking reduces the risk of flow restriction during tight bends, and the smooth bore promotes efficient coolant circulation. The matte black finish helps hide tubing runs and complements a wide range of system aesthetics while the material composition is chosen for chemical compatibility with typical coolant additives.

Suitable for

• Custom PC water cooling loops
• Tight or compact PC builds requiring flexible tubing
• Systems using push-fit and compression fittings
• Enthusiast and DIY cooling upgrades

Key specifications

• Color: matte black
• Flexible construction for tight bends
• Smooth inner surface for stable flow
• Resistant to kinking under normal installation
• Compatible with common push-fit and compression fittings

How to use

Measure and cut tubing to the required lengths for your loop, allowing small extra lengths to avoid strain on fittings. Slide the tubing firmly onto compatible fittings (push-fit or compression) ensuring a full seat and secure connection. Route the tubing to minimize tight 90-degree bends; where sharp turns are unavoidable, allow a gentle radius to maintain internal diameter. After assembly, perform a leak test with the system powered off and reservoir filled, running a pump-only test for several hours to verify connections and flow.

Recommendations

Use compatible coolant formulations and follow manufacturer guidance for additives to prevent degradation. Replace tubing if you observe discoloration, brittleness, or persistent flow restrictions. During maintenance, avoid sharp tools when trimming and ensure fittings are free of debris before reinstalling tubing.
