Product information

Description

Connection terminal OEM EK Water Blocks 3831109903445 is a transparent acrylic terminal designed for use in custom PC liquid cooling systems. Machined from cast acrylic (plexi), the terminal measures 41×72×23 mm and serves as a compact interface to route or join coolant channels between the GPU water block and the active backplate in compatible EK-Quantum Vector² Strix/TUF RTX 4080 and 4090 ABP setups. The part replaces the original black POM acetal terminal when a clear, glass-like finish is required and integrates with the DirectLink flow concept used in multiple-block solutions.

Advantages

The acrylic construction provides a clear view of coolant flow and a smooth finish that matches other plexi components. CNC machining ensures precise dimensions and clean sealing faces for reliable fitting with existing block and backplate assemblies. The terminal supports the conventional 4-port DirectLink layout, enabling flexible serial or parallel connections from adjacent or opposing sides. It is compact and compatible with setups that require space-efficient routing between the GPU water block and active backplate.

Suitable for

  • Custom water-cooled PC builds using EK-Quantum Vector² Strix/TUF RTX 4080 or 4090 ABP sets
  • Setups requiring a transparent terminal for visual coolant inspection
  • Configurations with vertical GPU mounts or distribution plates where routing flexibility is needed

Key specifications

  • Material: Cast acrylic (plexi)
  • Finish: Transparent
  • Dimensions (W×D×H): 41 × 72 × 23 mm
  • Flow layout: 4-port DirectLink-compatible terminal geometry
  • Manufacturing: CNC-machined

How to use

Install the terminal in place of the stock black acetal terminal on compatible EK-Quantum Vector² Strix/TUF RTX 4080 or 4090 ABP assemblies by following the water block and backplate manufacturer instructions. Transfer any required brass inserts and magnetic covers from the original terminal when your ABP set uses those components; these inserts and covers are not included with this acrylic terminal. Ensure sealing surfaces are clean and use appropriate gaskets or O-rings from the original assembly to maintain leak-free connections. Tighten fasteners to the specified torque values and confirm correct alignment of flow ports before filling the loop.

Usage recommendations

Use original brass inserts and magnetic covers from the OEM terminal to preserve DirectLink functionality and branding rotation options. Inspect O-rings and seals during replacement and perform a pressure or leak test before powering the system. Avoid strong solvents on acrylic surfaces and clean with a soft, lint-free cloth and mild soapy water to prevent scratching.
