Thermaltake CL-W031-CA00SL-A Pacific DIY LCS Chrome 1/2" ID x 5/8" OD Compression Fitting

The Thermaltake CL-W031-CA00SL-A is a G 1/4 compression fitting for connecting 1/2-inch ID × 5/8-inch OD PVC tubing in a custom PC liquid-cooling loop, suited to builders whose tubing matches those dimensions.

Recommended For

• Custom-loop builders using flexible PVC tubing sized 1/2-inch ID × 5/8-inch OD who need a matching compression fitting.
• PC water-cooling builders connecting compatible soft tubing to components with G1/4 ports.
• Builders who prefer a compression collar to help secure flexible tubing at each custom-loop connection.
• Builders matching chrome fittings to the visible hardware in a custom liquid-cooling loop.

Real-World Use Scenarios

• In a custom PC water-cooling loop, use it to connect a length of matching soft tubing to a G1/4 port on a compatible block, radiator, pump, or reservoir; it provides a threaded tube connection, but the loop still needs to be leak-tested before use.
• For a first custom-loop build, pair it with correctly sized soft tubing when you want to avoid hard-tube bending; the flexible tube can be cut and routed by hand, though tight turns need care to prevent kinks.
• When a case layout makes a straight tube run awkward, use matching soft tubing to route around nearby components; plan the path and bend gently so the tube does not kink or obstruct the loop.
• During a loop rebuild or expansion, use it to replace or add a connection when the existing soft tubing is 1/2-inch ID by 5/8-inch OD and the component port is G1/4; matching both tube dimensions helps avoid a mismatched connection.
• In a windowed build with visible loop fittings, choose the chrome finish to coordinate with other polished components; the finish changes the look of the loop, not its cooling performance.
