Alphacool Eiszapfen Pro 16mm Spare Parts 10 O-rings 1020230

Replacement O-rings for 16mm Eiszapfen Pro fittings

This pack supplies ten replacement O-rings designed for Alphacool Eiszapfen Pro 16mm hard-tube fittings. The wide rings sit inside the fitting body and create the primary seal against the tube. They are intended for builders maintaining or extending a custom liquid-cooling loop that uses these specific connectors.

O-ring material and PETG tube considerations

The O-rings are made to withstand the temperatures and compression forces found at CPU and GPU block outlets. PETG tubing is softer than acrylic and can deform under heat and pressure; the original nylon inserts that helped prevent this deformation are no longer included in the spare-parts kit. Users running PETG should be aware that the inserts must be sourced separately if required.

Not compatible with Bitspower tubing

Alphacool notes that these O-rings are not recommended for use with Bitspower-brand hard tubes, so builders mixing component brands should verify fitment before assembly. The kit directly replaces worn or lost seals in existing Eiszapfen Pro 16mm fittings, restoring leak-free operation without needing new fittings. It is not a fitting upgrade and does not add additional connectors or tubing.
