Tube Alphacool 18434 Acrylic glass Transparent 1.3 cm Diameter

The Alphacool tube in transparent acrylic glass is a rigid coolant line intended for custom liquid cooling systems. With a 1.3 cm outer diameter and an 80 cm length, this clear hard tube provides a visible coolant path that integrates with fittings and reservoirs used in PC water-cooling loops. The transparent acrylic material offers good optical clarity while maintaining the structural rigidity required for straight runs and precise routing inside a case.

Advantages

Transparent acrylic construction ensures high visual clarity for monitoring coolant flow and identifying air bubbles or contamination. The rigid tube maintains its shape without collapsing, which simplifies installation of compression fittings and prevents kinks. The straight 80 cm length reduces the number of joints needed in many loop layouts, helping to minimize potential leak points and improving overall flow consistency.

Suitable for

• Custom PC liquid cooling loops with rigid tubing
• Visible coolant routing where aesthetics and inspection are important
• Systems requiring precise, stable tube runs between components

Key specifications

• Material: transparent acrylic glass
• Outer diameter: 1.3 cm
• Length: 80 cm
• Type: rigid straight coolant tube

How to use

Measure the required tube length and mark cut points before installation. Use a fine-toothed saw or a tube cutter suitable for acrylic to obtain clean, square ends. Deburr and polish cut edges to ensure proper sealing with compression fittings. Insert the tube into compatible fittings and tighten according to the fitting manufacturer’s instructions, avoiding over‑tightening that could crack the acrylic. Route the tube to maintain gentle curves or use angled fittings where tight changes in direction are necessary.

Recommendations

Store the tube out of direct sunlight and away from high-temperature sources to prevent warping or discoloration. When bending is required, use appropriate angled fittings rather than forcing the rigid tube. Periodically inspect the tube for scratches, clouding, or micro-cracks and replace if any damage that could compromise a seal or structural integrity is found.
