Thermaltake Pacific CL-W033-CA00BL-A Pacific DIY LCS Black 3/8" ID x 1/2" OD Compression Fitting

The Thermaltake Pacific CL-W033-CA00BL-A is a black G1/4 compression fitting for DIY PC liquid-cooling builders using tubing with a 3/8-inch inner diameter and 1/2-inch outer diameter; its pre-installed O-ring supports a secure connection.

Recommended For

• Custom-PC builders assembling or expanding a water-cooling loop with flexible tubing sized 3/8-inch ID × 1/2-inch OD and G1/4 ports.
• Builders replacing a fitting in an existing soft-tube loop who want to keep the same tubing dimensions and use a black finish.
• DIY loop builders connecting flexible tubing to compatible G1/4 ports on water-cooling components; the fitting includes a preinstalled O-ring for the port connection.
• PC builders coordinating a black-themed custom loop who need a matching compression fitting for the specified flexible-tubing size.

Real-World Use Scenarios

• When building a soft-tube custom PC cooling loop, use these fittings to connect flexible tubing between compatible components such as a pump, radiator, and water blocks; the compression collar secures each tube connection.
• When choosing tubing for an existing loop, match both dimensions: this fitting is for flexible tubing with a 3/8-inch inner diameter and 1/2-inch outer diameter. A size mismatch can prevent a secure fit.
• When connecting tubing to a water block, radiator, or reservoir with a G1/4 port, the threaded end is designed for that connection; check the component port and available clearance before installation.
• When assembling or revising a loop, flexible tubing can be easier to route and adjust than rigid tubing, making it a practical choice for builds where the tube path may change during installation.
• When finishing a black-themed custom loop, the black fittings provide a consistent look at the tube-to-component connections; after filling, check the joints for leaks before putting the PC into regular use.
