HardTube fitting for 16 mm loops

This Alphacool Eiszapfen PRO fitting connects 16 mm PETG hard tubing using a standard G1/4 thread. The chrome finish suits custom water-cooling builds that value a clean metallic look. It is sold individually so buyers can match the exact number of joints their loop requires.

Nylon insert resists tube deformation

An internal nylon sleeve supports the tube wall, reducing the risk of PETG softening when coolant reaches 60 °C. The enlarged compression seal and O-ring distribute clamping force over a wider area, holding the tube firmly from both sides. Alphacool reports tensile testing beyond 8 kg without slip.

Replaces standard compression fittings

Builders who have seen PETG kink or walk out of ordinary fittings under load gain extra security here. The design is not recommended for Bitspower tubing, so users of that brand should choose a different fitting. The upgrade is worthwhile when loop temperatures approach the deformation threshold.

Questions about this item

What thread standard does the Alphacool 1017617 fitting use?

The fitting uses a G1/4 thread, the common standard for custom water-cooling components, allowing it to screw directly into radiators, blocks and reservoirs with matching ports.

Which tube size does the Eiszapfen PRO 16mm fitting accept?

It is designed for 16 mm outer-diameter hard tubing such as PETG or acrylic; the internal nylon insert grips the tube wall to prevent deformation up to 60 °C.

How do I install the fitting without the tube slipping?

Slide the compression ring and nylon insert onto the cut tube, push the tube fully into the fitting body, then tighten the collar by hand plus a quarter turn with a spanner to engage both the O-ring and the larger compression seal.
