High-Flow Chrome Fitting

The Alphacool Eiszapfen 16mm HardTube compression fitting connects 16mm acrylic or brass tubing to any G1/4 port. Its rotatable 45° design simplifies routing in custom liquid-cooling loops. The chrome finish resists chipping and peeling for long-lasting appearance.

Leak-Secure Construction

Slanted corners on the union nut press the O-ring firmly against the hard tube for a reliable seal that withstands transport vibration. The high-flow internal geometry minimises restriction while maintaining secure connections throughout the loop.

Universal G1/4 Compatibility

The 1/4-inch thread fits 95 percent of water-blocks, radiators, reservoirs and pumps on the market. Rotatable threading allows final alignment after installation without stressing the tube. One fitting is supplied per package.

Questions about this item

How do I install the 16 mm hard tube into this 45° rotatable G1/4 compression fitting and what step do people often miss?

Slide the union nut and compression ring onto the tube, push the tube fully into the fitting until it seats against the internal stop, then tighten the knurled nut by hand plus a quarter turn with a wrench; the step most people miss is confirming the tube is bottomed out before tightening, otherwise the O-ring will not seal properly.

What maintenance or replacement will this chrome-finished fitting need over time?

The bonded chrome coating resists chipping and peeling, so the fitting body itself rarely needs replacement; plan to inspect and, if necessary, replace the internal O-ring whenever you drain the loop or notice any seepage at the 16 mm tube connection.

What is the first limit I will hit when running this 45° rotatable fitting under sustained flow?

The 45° bend introduces a modest flow restriction compared with a straight fitting, so under sustained high-flow operation the pressure drop across the elbow becomes the limiting factor before the G1/4 thread or the 16 mm tube seal reach their limits.
