Alphacool Eiszapfen G1/4" 13mm ID 19mm OD Compression Fitting Black 6 Pack

Precision Water-Cooling Fittings

Alphacool Eiszapfen compression fittings connect 13 mm inner-diameter, 19 mm outer-diameter flexible tubing to any component with a G1/4" thread. The six-pack supplies enough connectors for a typical CPU-and-GPU loop or a dual-radiator build. Machined brass bodies with a deep black coating resist chipping and peeling through repeated assembly cycles. Each fitting includes three coloured O-rings for customisation or UV-reactive highlights.

High-End Loop Builders

These fittings suit enthusiasts who demand secure, high-flow joints and a consistent matte-black aesthetic across every visible connector. The slanted nut corners press the O-ring firmly against the tube wall, improving seal integrity during transport or case rotation. Installers who prefer push-fit or barbed connections, or who work with tubing sizes other than 13 mm ID and 19 mm OD, should select a different fitting style.

Coloured O-Ring Set Included

Every pack ships with O-rings in three distinct colours, letting builders colour-code flow paths or add UV-reactive accents without extra purchases. The durable surface treatment keeps the black finish intact even after multiple disassemblies, so the loop retains its original appearance over time. No additional tools or lubricants are bundled.
