Computer cooling system part THERMALTAKE CL-W030-CA00BL-A — copper, black, 24.7 mm height, 53 g

THERMALTAKE CL-W030-CA00BL-A is a compact copper compression fitting finished in black for custom PC water cooling loops. With an overall height of 24.7 mm and a weight of 53 g, this component is designed for integration into liquid cooling assemblies that require reliable copper heat transfer and a low-profile form factor. It is compatible with soft tubing sized for a 1/2" (13 mm) inner diameter and 3/4" (19 mm) outer diameter and mates to standard G1/4" ports when used as a compression-style connector.

Advantages

The copper construction offers high thermal conductivity and mechanical durability while the black plated finish provides corrosion resistance and a coherent appearance in dark-themed builds. The compression-style design with an O-ring ensures a secure, leak-resistant connection to tubing and cooling components. Its compact 24.7 mm height and moderate mass make it suitable for installations where space is limited yet reliable sealing and flow characteristics are required.

Suitable for

• Custom PC water cooling loops using soft tubing (1/2" ID × 3/4" OD)
• Replacement or upgrade of existing compression fittings in liquid cooling assemblies
• Compact cooling layouts with limited vertical clearance
• Builds seeking copper components for improved heat transfer and durability

Key specifications

• Material: copper (black plated finish)
• Height: 24.7 mm
• Weight: 53 g
• Tubing compatibility: inner diameter 1/2" (13 mm), outer diameter 3/4" (19 mm)
• Connection standard: compatible with G1/4" ports when used as compression fitting
• Design: compression fitting with O-ring for leak-resistant seal

How to use

Slide the compatible soft tubing onto the barb section of the fitting until it seats fully, then thread the compression ring and nut to tighten the assembly around the tubing. Ensure the preinstalled O-ring is present and in good condition before final tightening. Mount the fitting to a G1/4" port or corresponding compression interface and hand-tighten, then apply a small additional torque with an appropriate tool if required to obtain a secure, leak-free connection. Inspect the connection under lukewarm system pressure or a controlled leak test before full operation.

Usage recommendations

Use flexible tubing rated for the specified inner/outer diameters and perform a pressure/leak test after installation. Avoid over-tightening the nut to prevent damage to the O-ring or threading; replace the O-ring if signs of wear appear. For long-term corrosion protection and appearance, use compatible coolant and avoid mixing incompatible metals in the loop without appropriate inhibitors.
