## Summary description

Acrylic tube for liquid PC cooling systems by Alphacool (model 18438). Made of transparent acrylic glass, with outer diameter 13 mm and length 400 mm, designed to transport cooling liquid within custom loop setups. Suitable for visible tubing in desktop water-cooling, connecting reservoirs, radiators and blocks, offering rigid, clear conduit for coolant flow.

## Long description

Alphacool acrylic tube model 18438 is a rigid, transparent conduit designed for custom liquid cooling loops in desktop PCs. Manufactured from clear acrylic glass, the tube measures 400 mm in length with a 13 mm outer diameter and provides a visually unobtrusive and solid route for coolant between components such as reservoirs, radiators and water blocks. The product is intended for visible hard tubing installations where a firm, scratch‑resistant, and optically clear line is required.
Advantages
This rigid acrylic tube delivers a straight, transparent connection that preserves coolant clarity and offers a neat, structured appearance inside a PC chassis. Its smooth inner surface promotes unobstructed flow and eases cleaning compared with some flexible hoses. The rigid nature of the tube provides stable, vibration‑resistant runs and pairs with compatible hard‑tube fittings to create fully sealed joints for leak‑resistant operation.
Suitable for
 Custom PC water‑cooling loops with visible hard tubing
 Connecting reservoirs, radiators and water blocks in desktop systems
 Systems requiring rigid, straight coolant runs and a clear visual appearance
Key specifications
 Material: acrylic (plexi) glass
 Outer diameter: 13 mm
 Length: 400 mm
 Color/finish: transparent, clear
 Intended use: rigid hard tubing for liquid cooling
How to use
Cut the tube to the required length using an appropriate hard‑tube cutter or saw and deburr the ends for a clean fit. If bends are needed, use a dedicated acrylic bending tool or heat source designed for plexiglass to form smooth radiused curves; ensure uniform heating to avoid cracking. Install the tube with compatible Alphacool hard‑tube fittings or compression connectors to achieve sealed joints, and verify alignment before fully tightening fittings. Perform a leak test with the loop filled and pressurised according to the cooling system guidelines before powering the PC.
Usage recommendations
Use tubing clamps or properly rated fittings to secure joints and avoid over‑tightening fittings that could crack acrylic. Clean the inside with a soft, lint‑free cloth and appropriate coolant‑safe cleaners; avoid harsh solvents that can cloud or damage acrylic. Store spare tubes flat and away from direct sunlight to prevent long‑term UV exposure and potential yellowing.
