Tubing Alphacool 18663 EPDM Black 1.1 cm Diameter 100 cm Length

The Alphacool 18663 EPDM Black tubing is designed for computer liquid cooling systems and offers a combination of chemical resistance, dimensional stability and long service life. Made from EPDM rubber with a matte black velvet finish, this tube has an inner diameter of approximately 11 mm (1.1 cm) and a length of 100 cm, making it suitable for a wide range of PC water-cooling loops. Its material composition provides improved temperature tolerance and resistance to acids, alkalis and other external influences compared with conventional PVC tubing.

Advantages

EPDM construction provides higher temperature resistance and greater longevity than typical PVC hoses, remaining dimensionally stable at elevated water temperatures and tighter bending radii. The matte black surface gives a discreet, non-reflective appearance while resisting chemical attack and environmental ageing. The tube maintains flexibility for straightforward installation while reducing the risk of kinking, deformation or flow restriction over time.

Suitable for

• Custom PC water-cooling loops
• Replacement tubing in existing liquid-cooling systems
• High-temperature coolant applications within PCs
• Systems requiring chemically resistant tubing

Key specifications

• Material: EPDM rubber (ethylene propylene diene monomer)
• Colour: Matte black
• Inner diameter: 1.1 cm (11 mm)
• Length: 100 cm
• Properties: High resistance to acids and alkalis, enhanced thermal stability, good flexibility

How to use

Measure the required length of tubing for your loop and cut the Alphacool EPDM tube cleanly with a sharp tubing cutter or fine-toothed saw to ensure square ends. Slide the appropriate size fittings or clamps onto the tube and push the tube fully onto the barb or compression fitting until seated. For best results, use compatible Alphacool Eiszapfen or HF series fittings in the matching size. Check all connections for secure seating and test the system for leaks before full operation.

Recommendations

Allow for gentle bending radii when routing the tube to avoid excessive strain at connection points. Although EPDM tolerates higher temperatures, monitor coolant temperatures and perform a leak test after assembly. Use fittings sized to the tube's inner and outer diameters and avoid sharp kinks; periodic inspection is recommended to ensure long-term reliability.
