16 mm Hard-Tube Compression Fitting

The Alphacool Eiszapfen 1013366 is a 16 mm hard-tube compression fitting with a 45° rotatable G1/4 thread. It is designed for custom water-cooling builders who need a secure, angled connection between rigid tubing and standard components. The deep black finish matches dark-themed loops while the knurled union nut allows tool-free tightening during assembly.

Deep Black Coating and Rotatable Thread

A special bonding process anchors the matte black coating to the metal body, preventing chipping or peeling over time. Slanted corners on the union nut press the O-ring firmly against the tube for a tighter seal that resists vibration during transport. The G1/4 thread rotates freely, letting you orient the 45° bend without stressing the connected block or radiator port.

Verify Tube Material and Port Clearance

Confirm that your loop uses 16 mm outer-diameter acrylic or brass hard tube before ordering. Check that each component offers a G1/4 female port and that the 45° bend clearance fits within your chassis layout. The fitting is sold individually, so count the required angled connections in your planned routing.

Questions about this item

What thread standard does the 45° rotatable fitting use, and what share of components does it fit?

It uses a G1/4 thread, which the maker says is compatible with 95% of water-cooling components.

What tube size and material does the 16 mm compression end accept?

The compression end is sized for 16 mm outer-diameter hard tube, either acrylic or brass.

How do you secure the tube, and which step is often missed?

Slide the union nut and olive onto the tube, insert the tube fully into the fitting body, then tighten the nut until the slanted corners press the O-ring firmly against the tube; the step often missed is pushing the tube all the way in before tightening.
