Flow indicator for custom loops

The Alphacool 17366 Eisfluegel adds a visual flow indicator to a custom watercooling circuit. Its clear plexi housing and black fins create an aesthetic highlight while confirming coolant movement. The unit suits builders who want immediate visual verification that their loop is operating correctly. It is not for buyers who need an active pump or reservoir integrated into the same component.

Simple inline installation

The indicator connects inline using hoses with a 6 to 11 mm inner diameter. No tools or power connections are required beyond the standard tubing and fittings already used in the loop. The compact body measuring 88 by 40 by 15 mm fits tight routing paths. The only common issue is forgetting to orient the unit so the fins remain visible through the case window.

6 to 11 mm hose compatibility

The single specification that decides fitment is the accepted hose inner diameter range of 6 to 11 mm. If your loop uses tubing outside this range, the barbs will not seal correctly. Match this figure to your existing tubing before purchase.

Questions about this item

How can I confirm the flow indicator is working correctly once installed?

The black fins inside the clear body spin silently when coolant passes through, giving immediate visual confirmation of flow direction and rate.

What comes in the package and which fittings or tubing must I supply?

The indicator itself is included; you need to provide hoses or tubes with an inner diameter between 6 and 11 mm and suitable compression or barbed fittings to connect them.

Which version of the Eisfluegel should I choose for a standard custom loop?

Model 17366 with the clear plexi housing and black fins fits any loop using 6 to 11 mm ID tubing and adds a compact 88 x 40 x 15 mm visual flow check.
