BitsPower Crystal Link Tube 12/10mm 500mm – rigid transparent cooling tube for PC water cooling

BitsPower Crystal Link Tube 12/10mm 500mm is a rigid, transparent cooling tube engineered for custom PC water cooling loops. With an outer diameter of 12 mm and an inner diameter of 10 mm, this 500 mm hard tube provides a straight, stable conduit for coolant between fittings, radiators, pumps and water blocks. The clear material allows visual monitoring of flow and coolant condition while maintaining a precise, professional appearance in a bespoke loop.

Advantages

The rigid construction ensures minimal deformation under compression and steady alignment with compression fittings, reducing the risk of leaks compared with flexible tubing. Transparency enables easy visual inspection of coolant clarity and flow. The consistent inner diameter supports stable flow characteristics and predictable thermal performance. Its 500 mm length is suitable for creating neat, straight runs and maintaining a clean layout inside a PC chassis.

Suitable for

• Custom PC water cooling loops requiring hard tubing
• Connections between radiators, pumps, reservoirs and water blocks
• Builds that prioritise clean, straight runs and visible coolant
• Systems that use compression or push-fit fittings compatible with 12/10 mm tubing

Key specifications

• Material: rigid transparent tubing (clear hard tube)
• Outer diameter: 12 mm
• Inner diameter: 10 mm
• Length: 500 mm
• Compatibility: designed for use with standard PC water-cooling fittings for 12/10 mm hard tubing

How to use

Measure the required length and plan straight runs before installation. Cut the rigid tube squarely with an appropriate cutter designed for hard tubing, then deburr the ends to ensure a clean seat against fittings. Insert the tube into compatible compression or push-fit fittings, ensuring the tube is fully seated and compression rings or collars are tightened according to fitting manufacturer instructions. Pressure-test the loop after assembly to verify leak-free operation prior to powering the system.

Recommendations

Store the tube flat and away from direct sunlight or high heat prior to installation. Use compatible fittings rated for hard tubing with the specified outer/inner diameters. When cutting, use proper tools for rigid tubing and verify end faces are square to ensure secure sealing. Perform a leak test with coolant and monitor for any signs of stress or cracking after initial operation.
