Alphacool Eiszapfen Pro 13mm OD Inserts

These replacement O-rings and nylon inserts are made for Alphacool Eiszapfen Pro fittings that use 13mm OD hard tubing. They provide the sealing components needed to maintain a watertight connection in a custom liquid-cooling loop. The parts are sold new under article number 17565.

Suited for builders using PETG hard tubes

The nylon inserts stop PETG tubing from deforming under heat and compression, which can otherwise cause leaks at GPU or CPU outlets. This kit is not intended for acrylic tubing, which does not need the inserts, nor for Bitspower brand tubing, where fitment is not recommended.

Kit contains O-rings and nylon inserts for 13mm OD

The wide O-ring seals the tube inside the fitting while the insert supports the PETG wall against softening at higher coolant temperatures. Without the insert, PETG can collapse at restriction points and break the seal. Acrylic hard tubes do not require the insert, so this kit adds no benefit there.

Questions about this item

Will these inserts fit my existing Alphacool Eiszapfen Pro fittings for 13mm OD hard tubing?

Yes, they are made specifically for Alphacool Eiszapfen Pro fittings sized for 13mm OD HardTube.

Do I need these nylon inserts if I am reusing PETG tubing instead of acrylic?

Yes, PETG is softer than acrylic and can deform under heat and compression; the inserts prevent that deformation inside the fitting.

How can I confirm the inserts are seated correctly after assembly?

The wide O-ring sits inside the fitting body and the nylon insert sits within the tubing; a leak-free loop under pressure confirms correct seating.
