Watercool PCI Slot Pass-Through Bracket 2×2 G1/4 Black

SKU CH-WS5B-9SZ91

Connects an external radiator to an internal loop via two G1/4 ports per side without restricting flow

  • ColorBlack
  • FeaturesConnect external components like a MO-RA radiator to your in
  • Connect external radiators without case mods using ATX-standard bracket
  • Two G1/4 ports each side accept standard fittings and quick disconnects
  • High-diameter channels maintain full flow rate without restriction
  • Reinforced walls with quality O-rings ensure leak-free operation
  • Simple pass-through design links internal loop to outside components

External Loop Connection

The Watercool PCI slot pass-through bracket lets you route coolant from an internal loop to external hardware such as a MO-RA radiator. It occupies a single expansion slot and uses standardised G1/4 threads on both faces. The black finish matches most chassis interiors. No case modifications are required for installation.

Build Integration

The bracket follows ATX specifications so it aligns with any standard rear cut-out. Two G1/4 female ports on each side accept common fittings or quick-disconnects with male G1/4 threads. Internal channels are sized to avoid restricting flow rate. High-quality rubber o-rings and reinforced wall thickness keep the seal leak-free under pressure.

Capacity And Limits

The assembly provides four G1/4 ports in total, giving enough connectivity for a single external radiator or reservoir loop. It cannot accommodate more than one external circuit because only two independent channels are present. Builders needing multiple separate external loops will require additional brackets. The slot-mounted design also means it cannot be used in cases without a free PCI opening.

Questions about this item

Will the G1/4 channels restrict flow when the loop runs all day?

The internal channels have a very high diameter so they do not restrict flow rate even under sustained use.

Does the bracket generate noise or heat during continuous operation?

The bracket is a passive metal pass-through with no moving parts, so it produces no noise and adds no measurable heat.

Which fittings must I already own to connect this bracket?

You need standard male G1/4 fittings or quick-disconnects for the four ports on the bracket.
