THERMALTAKE CL-W043-CU00SL-A copper computer cooling system part — chrome, height 30 mm, weight 58 g

THERMALTAKE CL-W043-CU00SL-A is a chrome-finished copper extender fitting designed for PC water cooling systems. With a 30 mm height and a weight of 58 g, this component functions as a male-to-male G1/4 connector in custom or OEM cooling loops, enabling reliable thermal conduction and physical extension between cooling parts. The chrome plating provides corrosion resistance and a polished appearance while the copper body ensures effective heat transfer suitable for liquid-cooling assemblies.

Advantages

The chrome-plated copper construction combines good thermal conductivity with surface protection to reduce oxidation and maintain appearance. At 30 mm height and 58 g weight the fitting offers a compact, solid connection that is easy to handle during installation. Inclusion of quality O-rings ensures a secure seal to reduce risk of leaks when mounted to standard G1/4 ports. The standardized G1/4 thread compatibility allows integration with a wide range of radiators, blocks and fittings used in PC water cooling.

Suitable for

• Extending or joining two G1/4 threaded components in custom water cooling loops
• Replacement of worn or damaged male-to-male extender fittings
• Compact PC builds where a 30 mm chrome extender is required for alignment or clearance
• Enthusiast systems requiring corrosion-resistant, visually consistent fittings

Key specifications

• Material: copper with chrome plating
• Height / extension length: 30 mm
• Weight: 58 g
• Thread interface: G1/4 male-to-male connection
• Seal: supplied with O-rings for leak prevention

How to use

Turn off and drain the cooling loop before replacing or installing the extender. Thread the chrome copper fitting into the first G1/4 port by hand to engage the threads, then tighten gently with an appropriate wrench until snug — avoid over-tightening to prevent damage to threads or seals. Ensure O-rings are seated properly on each side to create a leak-free connection. Refill and bleed the loop, then inspect the joint for leaks at low and normal operating pressures before full system use.

Usage recommendations

Use the extender in systems designed for G1/4 threaded fittings and verify compatibility with connected components. Periodically inspect the chrome plating and O-rings for signs of wear or corrosion, and replace O-rings if swelling or damage is observed. When combining different metals in a loop, consider corrosion inhibitors or compatible coolant to minimize galvanic reactions.
