Alphacool 1013366 Eiszapfen 16mm 45° Rotatable G1/4 Knurled Deep Black fitting

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.
