Hard Tube Thermaltake CL-W065-PL16TR-A

The Thermaltake CL-W065-PL16TR-A Pacific V-Tubler is a 16mm (5/8") outer diameter PETG hard tube supplied as four 500mm lengths designed for custom PC liquid cooling systems. Constructed from 100% PETG, each rigid tube offers clear optical quality, consistent wall thickness and the dimensional accuracy required for fittings that match 16mm OD adapters. This tubing set is intended for PC builders who need straight runs, precise bends and visible coolant lines to complete an aesthetic and functional water-cooling loop.

Advantages

Manufactured from high-grade PETG, the tubing provides good clarity, chemical stability and reliable mechanical strength for typical PC cooling temperatures. Pre-cut 500mm segments in a four-pack supply enough length for multiple runs or radiator-to-component connections. The 16mm outer diameter is compatible with common 5/8" PETG fittings, making installation straightforward when using matching adapter hardware. Thicker walls reduce the need for excessive compression fittings and help maintain a consistent inside diameter for predictable flow.

Suitable for

• Custom PC water-cooling loops requiring visible, rigid tubing
• Connections between radiators, pumps, reservoirs and water blocks
• Systems using 16mm (5/8") OD PETG adapter fittings
• Enthusiast builds where clean tubing runs and aesthetic presentation are important

Key specifications

• Material: 100% PETG (polyethylene terephthalate glycol-modified)
• Outer diameter: 16 mm (5/8")
• Inner diameter: 12 mm
• Length: four pieces × 500 mm each
• Operating temperature range: approximately -20°C to 62°C (-4°F to 143.6°F)

How to use

Measure and plan tube runs before cutting to ensure precise lengths for straight sections and the required bend radii. Use a proper PETG tube cutter for clean, square ends and deburr the inner and outer edges if necessary. Fit the tubing onto compatible 16mm OD adapter fittings; for secure, leak-free connections, follow the fitting manufacturer’s torque and sealing instructions. When bending is required, heat the PETG evenly with a controlled heat source designed for hard tubing to achieve the desired radius without kinking, then cool while maintaining the bend shape.

Usage recommendations

Store tubes in a dry environment away from direct sunlight to preserve clarity. Use coolant formulations recommended for PETG systems and avoid aggressive chemicals. During assembly, work at moderate ambient temperatures within the specified operating range and test the completed loop for leaks at low pressure before returning the system to normal operation.
