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.

Questions about this item

Which fitting size do these 16 mm O-rings match?

They are made for Alphacool Eiszapfen Pro fittings that accept 16 mm outside-diameter hard tubing.

What tube types can I seal with these rings?

The rings seal both acrylic and PETG hard tube; PETG additionally needs the separate nylon insert to stop heat-induced deformation.

How do I install the wide O-ring without pinching it?

Slide the ring into the fitting's internal groove first, then push the tube straight in — twisting the tube while inserting is the step that damages the seal.
