Thermaltake Pacific SF Male to Male 20mm Extender Silver Black/DIY LCS/Fittings CL-W390-CU00SL-A

The Thermaltake Pacific SF CL-W390-CU00SL-A is a 20mm male-to-male G 1/4-inch copper extender for DIY liquid-cooling loops, suited to PC builders who need to bridge compatible threaded fittings or components.

Recommended For

• Custom-loop builders with compatible G1/4 ports who need a male-to-male connection extended by 20 mm; the 360-degree rotator helps set the fitting’s orientation during installation.
• Builders adding a more accessible drain or coolant-change point near a radiator, when pairing the extender with a compatible 90-degree fitting as Thermaltake describes.
• Custom-loop builders working around tight installation access who want a knurled fitting that is easier to grip and can be rotated while positioning.
• PC builders matching visible fittings to a silver-and-black custom-loop theme who specifically need a 20 mm male-to-male extender.

Real-World Use Scenarios

• To make radiator coolant changes easier, a builder can pair the extender with a separate 90-degree fitting under the radiator to position the outlet where it is easier to reach.
• When nearby fittings or hardware leave too little room, the 20mm extender can add space between G1/4 connections; check the fit in the case, since it adds another 20mm to the assembly.
• When planning a hard-tube loop, a builder can use the extender to shift a connection point by 20mm, which may help match the planned tube route without changing the component’s port position.
• During installation or loop disassembly, the fitting’s rotatable design can help the builder orient the connection more conveniently without relying only on how the threaded parts stop when tightened.
• When an existing custom loop needs a small layout change, the extender can add reach between compatible G1/4 ports, helping reposition a fitting or loop branch without replacing the radiator or water block.
