BitsPower Crystal Link Tube 16/14mm — rigid PETG coolant tube, 1000mm, black

BitsPower Crystal Link Tube 16/14mm is a rigid PETG-style coolant tube designed for custom PC liquid cooling loops. The tube has an outer diameter of 16mm and an inner diameter of 14mm with a length of 1000mm, finished in black to provide a clean, consistent coolant channel for radiator, reservoir and block connections. This rigid tube is intended for precise routing and visual uniformity in water-cooling builds where straight runs and firm placement are required.

Advantages

The rigid PETG construction ensures dimensional stability and resistance to deformation during bending and installation when properly heat-formed. The 16/14mm diameter balances flow capacity with compact routing, while the 1000mm length offers flexibility for cutting to exact measurements for one or more loop sections. The black finish hides minor internal discoloration and contributes to a uniform appearance inside the case.

Suitable for

• Custom PC water-cooling loops requiring straight, rigid tubing runs
• Connections between radiators, pump/reservoir combos and water blocks
• DIY loop assemblies where precise, cut-to-length tubing is needed
• Aesthetic builds that require a consistent black coolant channel

Key specifications

• Material: rigid PETG-style plastic
• Outer diameter: 16 mm
• Inner diameter: 14 mm
• Length: 1000 mm (one continuous tube)
• Color/finish: black

How to use

Measure and mark the required tube lengths for your loop, then cut the tube squarely using a fine-toothed saw or tube cutter. Heat the tube sections evenly with a heat gun to soften the material for bending or shaping; use a bending jig or form to achieve consistent radii. After forming, allow the tube to cool and harden completely before installing. Slide compatible compression fittings or clamps onto the tube ends and push the tube onto the fittings until seated; secure per the fitting manufacturer’s instructions. Leak-test the assembled loop with low-pressure distilled water prior to powering system components.

Использование и советы

Maintain clean cuts and even heating to prevent stress points. Use appropriate fittings sized for 16/14mm tubing and perform a careful leak test. Avoid exposing the tube to direct flames or prolonged high temperatures that exceed PETG working limits.
