Thermaltake Pacific 10mm Extender Fitting

The Thermaltake Pacific CL-W045-CU00BL-A is a G 1/4 female-to-male extender fitting built for custom liquid-cooling loops. It adds 10 millimetres of spacing between components without restricting flow. The black chrome-plated brass body suits builders who need precise tube routing in tight layouts.

10mm Offset With High-Flow Path

The fitting provides a straight 10 millimetre extension while maintaining a high-flow, leak-free channel. Its internal bore matches standard G 1/4 threads so coolant moves freely. The 22 by 15 millimetre profile fits most block and radiator ports. It cannot bridge larger gaps or replace angled adapters.

Brass Construction With Pre-Installed Seal

The copper-alloy body weighs 27 grams and resists corrosion under normal loop temperatures. A pre-installed O-ring seals the G 1/4 interface without extra tape or paste. The rigid metal construction adds negligible thermal load and produces no noise. It draws zero power.

Questions about this item

Will the G 1/4 threads on this extender fit the fittings already on my older radiator and blocks?

Yes — both ends use standard G 1/4 threads, so they mate with any component that follows the same thread spec.

How can I confirm the extender is seated correctly and not leaking after I install it?

Tighten each side by hand until the pre-installed O-ring compresses, then run a leak test with the pump only; no drops at the joints means it is sealed.

Does the package include any tubing, clamps or extra O-rings, or is it just the single extender?

The box contains the black chrome-plated brass extender fitting only; tubing, clamps and spare O-rings must be purchased separately.
