Thermaltake Pacific SF Male to Male 20mm Extender Matte Black/DIY LCS/Fittings CL-W390-CU00MK-A

The Thermaltake Pacific SF is a matte-black, 20mm male-to-male extender fitting for DIY PC liquid-cooling loops, suited to builders who need a compact G 1/4-threaded connection between compatible fittings or components.

Recommended For

• Custom-loop builders bridging two G1/4 female-threaded ports who need a fixed 20 mm male-to-male extension.
• Builders adjusting a liquid-cooling fitting during installation or disassembly; the extender has a 360-degree revolvable design.
• Custom-loop users routing a drain connection beneath a radiator, where adding an extender and a 90-degree fitting can make coolant changes easier.
• Builders finishing a custom liquid-cooling loop with matte-black fittings who need a compact 20 mm connector rather than a tubing compression fitting.

Real-World Use Scenarios

• When two G1/4 female-threaded ports need a short male-to-male connection, a builder can use this extender to join them and add 20 mm of separation; confirm the port layout and clearance before installation.
• When a radiator port is difficult to reach, a builder can place the extender beneath a compatible 90-degree fitting to raise it for easier access, including when setting up a coolant-change point.
• During loop assembly, a builder can use the rotating fitting to adjust its orientation after threading it into place, helping align the connected parts without needing to reposition the whole component.
• In a custom-loop build with limited space around a port, a builder can add the 20 mm extender to move the next fitting away from the port; whether it resolves a clearance issue depends on the surrounding components and tubing route.
