## Long description

EK Water Blocks fitting 3831109851326 is a brass push-in connector finished in gold, designed for custom PC liquid-cooling loops. With a compact 10 mm height and 16.5 mm outer diameter, this fitting is intended for use with rigid tubing and captive runs where minimal profile and a secure connection are required. Machined brass construction with gold plating and an internal EPDM rubber gasket provide corrosion resistance and a sealed grip on tubing. The product is manufactured in Slovenia and is compatible with EK Water Blocks cooling components.
Advantages
The brass body with genuine gold plating offers durable corrosion resistance and a consistent surface finish that integrates visually with premium cooling hardware. The internal EPDM gasket secures solid tubes and helps maintain leak-free joints. Compact dimensions make this fitting suitable for tight clearances and captive tube routes, while CNC machining yields precise tolerances for reliable mating with other components.
Suitable for
Custom PC liquid-cooling loops using rigid acrylic or PETG tubing
Short captive tube runs between blocks, radiators, or distributor plates
Installations requiring a low-profile connector in constrained spaces
Key specifications
Material: brass body with gold plating
Sealing: internal EPDM rubber gasket
Height: 10 mm
Outer diameter: 16.5 mm
Finish: gold
Manufacturer country: Slovenia
How to use
Prepare the rigid tube end square and clean. Insert the solid tube into the fitting until the tube seats against the internal stop; the EPDM gasket will compress to form a seal. For installations where the barb feature must be tightened, use a 9 mm Allen key or a purpose-made multi Allen key tool to engage the internal hex socket—apply controlled torque and avoid excessive force to prevent damage to fittings or adjoining cooling components. Verify alignment for captive runs so the tube cannot move when the system is assembled.
Usage recommendations
Use with 12 mm solid tubing such as acrylic or PETG for optimal grip. Do not allow axial movement of the tube in captive installations. When tightening with an Allen key, use an appropriate tool and moderate force to avoid damage. Confirm compatibility with other EK components and follow standard liquid-cooling assembly and leak-testing procedures before powering the PC.
