Replacement End Cap for Cape Coolplex

The Alphacool Cape Coolplex 3 Port End Cap 29050 is a direct replacement part for the Cape Coolplex reservoir series. It provides three G1/4" ports to integrate the reservoir into a custom liquid-cooling loop. The component is aimed at builders who need to restore or reconfigure their existing Cape Coolplex unit.

Simple Passive Component

As a static metal fitting, the end cap adds no active heat, noise or power draw to the system. Thermals and acoustics remain entirely dependent on the pump, radiators and fans chosen for the loop. The part simply seals the reservoir and routes coolant through its three threaded openings.

Fits Cape Coolplex Reservoirs

The cap threads directly onto a compatible Alphacool Cape Coolplex reservoir body using the standard G1/4" interface. It frees up three connection points for tubing, fittings, sensors or drain valves within the loop. Builders without a Cape Coolplex reservoir cannot use this end cap.

  • Direct replacement restores original Cape Coolplex sealing integrity
  • Single-piece acetal construction resists coolant corrosion long-term
  • Simple thread-in installation requires no special tools

Questions about this item

How do I install the 3-port end cap on my Cape Coolplex reservoir?

Remove the original end cap, align the three G1/4" ports, and hand-tighten the new cap until the O-ring seats evenly; over-tightening strips the acrylic threads.

What maintenance will the replacement end cap need later?

Inspect the three G1/4" O-rings annually and replace them if they flatten or crack; the cap body itself requires no scheduled service.

What limit appears first when the loop runs under sustained load?

The acrylic reservoir body reaches its temperature ceiling before the G1/4" end cap, so monitor coolant temperature rather than the cap.
