Eiszapfen 13mm G1/4 HardTube Fitting Sixpack

The Alphacool Eiszapfen series delivers high-end compression fittings for 13mm outer-diameter hard tubing with a G1/4 thread. A knurled nut design secures the tube firmly, while a special coating process resists chipping and peeling. The chrome finish suits custom loops where visual consistency matters.

Verify tube diameter and thread compatibility

Confirm that every tube in your loop measures 13mm outer diameter and that all components accept a G1/4 thread before ordering. The package includes O-rings in three colours for aesthetic choice, and an optional UV-reactive variant is available. Ensure your existing blocks, radiators and reservoirs present matching G1/4 ports.

Sustained loop integrity under vibration

The slanted nut corners press the O-ring evenly against the tube wall, maintaining a reliable seal during transport and continuous pump operation. This mechanical lock reduces the risk of slow leaks that can develop from vibration or thermal cycling over time. The durable chrome coating preserves appearance through repeated assembly and disassembly.

Questions about this item

Does the sixpack include the 13 mm hard tubes or only the chrome G1/4 compression fittings?

The package contains six chrome G1/4 compression fittings for 13 mm hard tube; the tubes themselves are not included and must be purchased separately.

Should I choose the chrome finish or the matte black version for a UV-reactive build?

Both finishes are offered; the chrome version ships with O-rings in three colours that glow under UV light, so it supports a UV-reactive theme directly.

Will the 13 mm G1/4 fittings work with standard 13 mm OD hard tubing in a custom loop?

Yes, the knurled compression nuts and slanted-corner design press the O-ring firmly against 13 mm OD hard tube for a secure, leak-free seal.
