Tubing Alphacool 18662 EPDM Black 1.3 cm

The Alphacool EPDM tube from the Enterprise Solutions series is a matt black tubing designed for custom liquid cooling systems. Made of EPDM rubber, it offers greater temperature resistance and longer service life than conventional PVC hoses, while its discreet velvet appearance suits visible water-cooled PC builds. The tube is sold individually and intended for use in cooling loops with compatible compression or push-fit fittings.

Advantages

EPDM material provides high resistance to acids, alkalis and external influences, delivering enhanced durability and longevity compared with standard PVC tubing. The tube remains dimensionally stable at elevated temperatures—well above 100 °C—reducing the risk of deformation at tight bends or connections and helping to prevent leaks or flow obstruction. Despite increased stability, the hose retains good pliability and flexibility for straightforward assembly.

Suitable for

• Custom PC liquid cooling loops
• Connections requiring a 1.3 cm outer diameter tubing
• Systems exposed to higher coolant temperatures or aggressive environments

Key specifications

• Material: EPDM rubber
• Color: Matt black
• Outer diameter: 1.3 cm
• High temperature resistance (service temperatures above 100 °C)
• Flexible with good dimensional stability

How to use

Cut the EPDM tubing to the required length with a sharp tubing cutter to ensure a straight end. Fit the tube onto appropriate fittings from Alphacool Eiszapfen or HF series (or other compatible fittings of the corresponding size) and secure according to the fitting manufacturer's instructions. Check that bends respect the tube's minimum bending radius to avoid excessive stress; the tube's pliability allows installation in tighter radii than many rigid hoses.

Recommendations

For reliable long-term operation, pair the tubing with compatible compression or clamping fittings in the correct size, inspect connections after initial filling and during periodic maintenance, and avoid prolonged exposure to strong solvents outside of typical coolant solutions.
