## Summary description

Fitting by EK Water Blocks (model 3831109905463) for custom PC liquid cooling loops. Machined brass construction with a titanium-colour finish. Compact dimensions: width 23 mm and height 21 mm. Designed to connect tubing and components in water-cooling systems, providing a durable sealed connection for radiators, blocks and reservoirs in desktop builds.

## Long description

EK Water Blocks 3831109905463 is a brass panel-mounted pass-through fitting with a satin titanium finish, designed for custom PC liquid cooling loops. Machined from brass and plated for a titanium-colour appearance, the compact adapter measures approximately 23 mm in width and 21 mm in height. Fitted with female G1/4" BSP threads on both ends, it provides a sealed threaded interconnection for tubing, radiators, water blocks and reservoirs in desktop and small form-factor builds. The fitting is secured to a chassis panel using the supplied grip nut, enabling external radiator or component routing when internal space is limited.
Advantages
This EK Water Blocks pass-through fitting offers durable CNC-machined brass construction with a satin titanium-colour surface that resists corrosion and wear while matching common cooling hardware aesthetics. Dual female G1/4" BSP threads allow direct threaded connections without additional adapters, and the compact dimensions suit cramped or small form-factor (SFF) cases. The included grip nut secures the adapter to panels, producing a reliable sealed connection between separate chassis compartments.
Suitable for
Small form-factor (SFF) and compact PC cases that require external radiator or component routing
Panel-mounted liquid cooling through-ports between separate chassis compartments
Custom water-cooling loops using G1/4" threaded components
Key specifications
Material: CNC-machined brass
Surface finish: satin titanium-colour plating
Thread type: female G1/4" BSP on both ends
Width: approximately 23 mm
Height: approximately 21 mm
Mounting method: panel-mounted with supplied grip nut
How to use
Install the fitting by inserting it into a suitably sized hole in the chassis panel and securing it with the supplied grip nut from the opposite side to achieve a firm panel mount. Thread compatible G1/4" fittings, extensions or hose barb adapters into the female threads to connect tubing, radiators, water blocks or reservoirs. Ensure thread sealing and leak prevention by using appropriate PTFE tape or approved sealing methods on threaded connections as required for your loop design. Tighten fittings to a firm, hand-assisted torque to avoid cross-threading or overtightening.
Usage recommendations
Use this adapter in systems that require external routing or compartmentalized cooling; verify compatibility with your existing G1/4" components before assembly and perform a full leak test after installation.
