Buying Guide: Choosing the Best Acrylic Tubing for Water Cooling

Tubing Material

• PETG (Polyethylene Terephthalate Glycol-modified) is a popular choice due to its durability, flexibility, and ease of use.
• Acrylic (PMMA) is a more rigid and brittle option but can provide a sleeker, more professional look.

Tubing Diameter

• Common sizes include 10mm ID x 14mm OD, 12mm ID x 16mm OD, and 14mm OD.
• Choose a diameter that is compatible with your water cooling components and fittings.

Tubing Length

• Consider the size of your case and the complexity of your water cooling layout when selecting the appropriate tubing length.
• Opt for longer lengths (e.g., 500mm or 750mm) to have more flexibility and room for error when cutting and bending the tubing.

Ease of Use

• PETG tubing is generally easier to work with, requiring less expertise to cut, bend, and install.
• Acrylic tubing may require more specialized tools and techniques, making it better suited for experienced water cooling enthusiasts.

Budget

• Acrylic tubing is typically more expensive than PETG, but the final cost can vary depending on the brand and pack size.
• Consider the overall cost of the tubing, fittings, and any additional tools or accessories needed for your custom water cooling setup.

FAQ

What is the difference between PETG and acrylic tubing?

PETG tubing is more flexible and easier to work with, making it a popular choice for beginners. Acrylic tubing is more rigid and can provide a sleeker, more professional look, but requires more expertise to cut and bend.

Do I need to chamfer the edges of acrylic tubing?

Yes, it is recommended to chamfer the edges of freshly cut acrylic tubing (typically a 0.5mm x 45-degree chamfer) to prevent damage to the gaskets or O-rings in your water cooling fittings.

Can I heat-bend acrylic tubing?

Yes, acrylic tubing can be heat-bent, but it requires more skill and specialized tools compared to bending PETG tubing. The GOWENIC Silicone Bending Insert can be a helpful accessory for this process.

What is the best way to cut acrylic tubing?

The best way to cut acrylic tubing is with a fine-toothed hacksaw or a dedicated tubing cutter. Cutting the tubing straight and chamfering the edges is essential for a clean, secure fit with your water cooling fittings.

How do I clean acrylic tubing?

To clean acrylic tubing, use a mild detergent and warm water. Avoid abrasive cleaners or solvents, as they can damage the tubing’s surface. Rinse thoroughly and dry completely before reinstalling the tubing in your water cooling system.

Conclusion

Selecting the best acrylic tubing for your water cooling setup is a crucial decision that can make or break the overall look and performance of your custom build. By considering factors like material, diameter, length, ease of use, and budget, you can find the perfect tubing solution to suit your needs and create a stunning, high-performing system. Whether you choose the versatile PrimoChill PETG tubing, the sleek EKWB acrylic hard tube, or any of the other options covered in this guide, you can be confident that you’re investing in a quality product that will enhance your custom water cooling experience.
