Alphacool Eiszapfen 16mm G1/4 Fitting

This Alphacool Eiszapfen compression fitting connects 16mm outer-diameter hard tubing to a G1/4 threaded port. The knurled nut provides grip for hand tightening. A durable black coating resists chipping and fading. The package includes one fitting and three coloured O-rings for customisation.

Suits custom loops using 16mm rigid tubing

Builders using soft tubing or a different outer diameter cannot use this fitting. Systems requiring angled or rotary adapters need separate components. The single G1/4 thread fits standard water-blocks and radiators but will not match proprietary thread sizes.

Hand-tighten the knurled nut onto the prepared tube

Cut the hard tube square and chamfer the edge before insertion. Push the tube fully into the fitting until it seats against the internal stop. Overtightening can damage the O-ring or tube. Ensure the G1/4 threads match the target component to avoid leaks.

Questions about this item

What hard-tube outer diameter must I already have for the 16 mm compression end to seal?

The fitting accepts rigid tubes with a 16 mm outside diameter.

Will the G1/4 thread mate with the blocks and radiators I already use?

Yes, the ¼-inch external thread is the standard G1/4 size used by most water-cooling components.

How can I verify the fitting is seated correctly after assembly?

The knurled nut presses the O-ring firmly against the tube; a snug, leak-free joint with no visible gap confirms proper seating.
