Reservoir Fittings
Fittings that go into the reservoir itself rather than into a block or a radiator. Their job is to stop the incoming flow from stirring the reservoir into a whirlpool, which pulls air into the pump inlet and gives you a loop that never fully bleeds.
Stocked here: the Alphacool Bubble Down in black, which breaks the incoming jet before it hits the coolant surface, Barrow anti-cyclone adapter fittings in black and silver, and the Alphacool ES 5/3mm compression fitting in deep black.
If your reservoir looks like it is boiling on fill day, this is the part that fixes it.
