Tubing Alphacool 18645 EPDM Black 1.1 cm

The Alphacool 18645 EPDM tubing is made from durable EPDM material and is designed for water-cooled PC systems. The matte black finish with a subtle velvet look offers a discreet aesthetic while the material provides high resistance to acids, alkalis and external influences, delivering longer service life compared to conventional PVC tubes.

Advantages

EPDM tubing withstands significantly higher temperatures than typical PVC tubing and remains dimensionally stable at temperatures well above 100 °C, reducing the risk of deformation at tight bends and connections. Its high resistance to chemicals and environmental factors makes the tube long-lasting and less prone to leaks or flow restrictions. The matte black appearance integrates unobtrusively into most water-cooling builds.

Suitable for

• Custom water-cooling loops in desktop PCs
• Connections between radiators, pumps and reservoirs
• Systems requiring chemically resistant and heat-stable tubing

How to use

Measure and cut the EPDM tube to the required length for your loop, allowing for bends and fittings. Slide the tube over compatible fittings from Alphacool (Eiszapfen or HF series) or other appropriately sized fittings, ensuring a secure connection. EPDM’s pliability allows installation around tighter radii; however, verify that bends do not exceed the tube’s minimum bending radius to maintain flow and prevent strain on connections.

Recommendations

For reliable performance, use the tube with fittings of the correct size and inspect connections periodically for wear or loosening. Avoid contact with solvents not compatible with EPDM and do not expose the tube to prolonged temperatures beyond the rated working range. When assembling, ensure clean cut ends and secure clamps or compression fittings where applicable.
