Tube Alphacool 18575

The Alphacool 18575 tube is a transparent polyvinyl chloride (PVC) tubing designed for custom liquid cooling systems. With an outer diameter of 1.6 cm and a length of 3 m, this tube provides a clear, durable conduit for coolant and is intended to deliver reliable flow and good heat transfer characteristics in PC water-cooling loops.

Advantages

Produced in Germany, the tube offers consistent quality and deep, intense colours that come from the tubing material itself rather than additives in the coolant. The formulation balances flexibility and dimensional stability to enable tight bends and convenient installation in compact or complex builds while minimising the risk of colour particles entering the coolant.

Suitable for

• Custom PC liquid cooling loops
• Replacement or upgrade of existing PVC tubing
• Systems requiring visible coolant routing with coloured tubing
• Builds where tight bend radius and ease of routing are required

How to use

Cut the tube to the required length using a suitable tubing cutter or a sharp blade to ensure a square end. Slide fittings, clamps or compression fittings onto the tube according to the fitting manufacturer’s instructions, then attach to radiators, pumps and water blocks. When routing the tube, avoid overly sharp kinks; use bends or rotary fittings where needed to maintain smooth coolant flow. Inspect connections and perform a leak test before powering the system.

Recommendations

For long-term use, flush the loop and replace the coolant at regular service intervals recommended for your cooling components. Use compatible coolants and additives designed for PVC tubing and avoid prolonged exposure to aggressive chemicals or solvents that may degrade the material.
