Cooling System Thermaltake CL-W031-CA00SL-A

The Thermaltake CL-W031-CA00SL-A is a compact, high-performance cooling component finished in chrome and built from durable copper. At 24.7 mm height and weighing 55 g, the unit is designed for efficient heat dissipation and reliable long-term use in custom liquid cooling loops and compact cooling assemblies. Its construction and chrome coating match aesthetic and functional demands of enthusiast builds while providing secure connections to standard G1/4" cooling ports when used with compatible compression fittings and tubing.

Advantages

The chrome-plated copper construction delivers good thermal conductivity and corrosion resistance compared with lower-quality materials. Its low profile and light weight make installation simpler in space-restricted systems, and the compatibility with standard G1/4" ports and compression fittings ensures a leak-resistant interface when assembled with proper O-rings and tubing. Manufactured to Thermaltake quality standards, this component integrates visually with chrome or black liquid-cooling hardware and supports modular expansion using other Pacific Series parts.

Suitable for

• Custom PC water cooling loops and radiator connections
• Enthusiast builds requiring chrome-finished fittings and compact components
• Small-form-factor systems where low profile and light weight are important
• Systems using 1/2" (13 mm) inner diameter and 5/8" (16 mm) outer diameter tubing

Key specifications

• Material: Copper with chrome coating
• Height: 24.7 mm
• Weight: 0.055 kg
• Compatible tubing: inner diameter 1/2" (13 mm), outer diameter 5/8" (16 mm)
• Interface: Designed for G1/4" threaded ports when used with compatible compression fittings
• Finish: Chrome

How to use

Install the component as part of a liquid cooling loop by sliding the appropriate flexible tubing over the fitting, ensuring the tube matches the specified inner and outer diameters. Use the matching compression collar and tighten to secure the tubing and create an even seal around the preinstalled O-ring. Thread the fitting into a G1/4" port on radiators, blocks, or reservoirs, and tighten by hand then finish with a small turn using an appropriate tool to avoid over-tightening. After assembly, pressure-test the loop before full system operation to confirm there are no leaks.

Usage recommendations

Use high-quality flexible tubing of the specified diameters and verify the O-ring is seated correctly before tightening. When combining with other Thermaltake Pacific Series components, follow the manufacturer’s instructions for torque and sequence to maintain leak-free performance and visual consistency in chrome- or black-finished systems.
