The Aqua-Computer 12–20 mm galvanized steel tube, model 68013 is a rigid metal conduit designed for use in liquid cooling loops and small-scale fluid systems. This galvanized steel tube offers a corrosion-resistant surface and mechanical strength for routing coolant, forming rigid link segments, and creating robust connections between fittings. Its dimensional range, from 12 mm to 20 mm, makes it suitable for a variety of plumbing layouts where a sturdy, long-lasting metal tube is preferred over softer materials.

Advantages

The galvanized steel construction provides resistance to rust and environmental degradation while maintaining structural rigidity under mechanical stress. The tube's smooth interior supports steady fluid flow and minimizes turbulence in confined sections of a cooling loop. Its durability makes it compatible with repeated installation and removal cycles and with fittings that require a firm seating surface. The metal finish also offers consistent dimensional stability compared with many plastic alternatives.

Suitable for

• PC liquid cooling loops requiring rigid metal link segments
• Custom cooling assemblies and small fluid distribution systems
• Routing coolant between reservoirs, pumps and radiators where metal tubing is preferred
• Plumbing connections that demand corrosion resistance and mechanical strength

Key specifications

• Material: galvanized steel
• Diameter range: 12–20 mm (suitable for matching fittings and connectors within this range)
• Surface: corrosion-resistant galvanized coating
• Form factor: rigid straight tube for fixed routing and link segments

How to use

Measure and cut the galvanized steel tube to the required length using an appropriate metal-cutting tool, ensuring square, burr-free ends for reliable connections. Deburr and clean cut edges before assembly. Slide compatible fittings or compression connectors over the tube and tighten according to the fitting manufacturer’s specifications to create leak-free joints. Verify compatibility of all materials in the fluid loop to avoid galvanic corrosion with dissimilar metals and ensure all seals and clamps are properly installed prior to system fill and pressure testing.

Usage recommendations

Use the tube in systems with compatible coolants and fittings; avoid prolonged exposure to highly acidic or alkaline fluids that can compromise galvanized coatings. When installing, support long runs to prevent sagging and reduce mechanical stress on joints. Perform a pressure test and visual inspection after assembly and before prolonged operation.
