Tube Alphacool 18439 Acrylic glass Transparent 1.3 cm 60 cm

The Alphacool 18439 acrylic glass tube is a transparent rigid tube designed for custom liquid cooling loops in computer systems. With an outer diameter of 1.3 cm and a length of 60 cm, this straight acrylic tube offers high optical clarity and mechanical rigidity, making it suitable for visible coolant runs and precise routing inside cases. The material provides a smooth finish and consistent wall thickness for reliable connection with standard compression fittings and adapters intended for rigid tubing.

Advantages

This transparent acrylic tube delivers clear visual presentation of coolant flow while maintaining good dimensional stability and resistance to typical workshop handling. The rigid construction reduces the risk of kinking or deformation found in flexible hoses and preserves straight runs with clean bends when used with appropriate bending tools or fittings. Its polished surface improves light transmission and complements LED illumination in builds where aesthetics and component visibility are important.

Suitable for

• Custom PC liquid cooling loops with rigid tubing
• Visible coolant runs where clarity and aesthetics matter
• Systems requiring straight rigid sections between fittings and components
• DIY projects and display cooling setups

Key specifications

• Material: acrylic glass (rigid)
• Outer diameter: 1.3 cm
• Length: 60 cm
• Color/finish: transparent, polished surface
• Compatibility: designed for use with compression fittings and adapters for rigid tubing

How to use

Measure and mark the tube to the required length, then cut using a fine-toothed saw or dedicated tubing cutter to achieve a square, clean edge. Deburr and polish the cut ends before installing to ensure a tight seal with compression fittings. Insert the tube squarely into the fitting and tighten according to the fitting manufacturer's torque recommendations. For bends or angled sections, use appropriate angled fittings or a heat bending method designed for acrylic, taking care to control temperature and avoid overheating the material.

Recommendations

Store the tube away from direct sunlight and strong solvents to prevent discoloration or surface damage. When assembling a liquid cooling loop, test the system for leaks with distilled water or recommended testing fluids before adding coolant or powering the PC. Use compatible fittings sized for a 1.3 cm outer diameter and follow device manufacturer guidance for secure, leak-free installation.
