High-End Chrome Fitting for 13mm HardTube

The Alphacool Eiszapfen 1012933 is a premium compression fitting designed for custom water-cooling loops using 13mm outer-diameter hard tubing. Its chrome finish undergoes a special binding process that resists chipping and peeling for long-lasting appearance. The knurled union nut features slanted corners to press the O-ring securely against the tube, improving hold during transport and operation.

G1/4 Thread Compatibility and 90° Rotatable Design

The fitting connects via a standard G1/4 thread, which fits 95 percent of water-cooling components such as radiators, blocks and reservoirs. A 90-degree bend in the body simplifies routing in tight spaces, while the rotatable threaded base allows the fitting to be oriented freely after installation without stressing the tube or seal.

Verify Tube Material and Loop Clearance Before

Confirm that your loop uses 13mm acrylic or brass hard tubing, as this fitting is not compatible with soft tubing or other diameters. Ensure the 90-degree profile and overall length suit the available space around your components, and that a single G1/4 port is free on each device you intend to connect.

Questions about this item

Should I choose the 13 mm or a different tube size?

This fitting is made for 13 mm hard tube only; the other side uses a standard G1/4 thread that fits 95 % of water-cooling components.

How does the 90° angle affect flow in my loop?

The 90° bend lets you route tube directly between blocks without extra hose, and the rotatable thread lets you orient the fitting after tightening.

What does the G1/4 thread limit in practice?

G1/4 is the near-universal thread for water-cooling parts, so the fitting connects to virtually any block, radiator or reservoir with that port.
