Hard-tube fitting for 16 mm PETG loops
The Alphacool Eiszapfen PRO is a G1/4 compression fitting designed for 16 mm PETG hard tubing in custom water-cooling builds. It targets builders who want a secure seal without relying on standard O-ring pressure alone. The deep black finish matches dark-themed loops. A single fitting is supplied in the package.
Nylon insert reinforces tube against heat
The fitting uses an internal nylon insert that stabilises the hard tube from the inside while a compression seal grips the outside. This dual reinforcement prevents the tube from slipping even when coolant temperatures approach 60 °C, where PETG can begin to soften. The larger contact area of the seal improves hold compared with conventional O-rings. No special tools are required beyond standard G1/4 threading.
Tested to over 8 kg tensile load
Alphacool reports the joint withstands more than 8 kg of pulling force, giving ample headroom for vibration or case movement. The design is not recommended for use with Bitspower brand tubing, so builders using that tubing should choose a different fitting. The fitting adds no flow restriction beyond the normal G1/4 port. It suits single-loop builds where long PETG runs must stay rigid.

Questions sur cet article
At what temperature can the PETG hard tube start to deform inside this fitting?
The PETG hard tube can begin to deform at 60 °C, which the Eiszapfen PRO fitting is designed to prevent by using internal nylon inserts that stabilise the tube.
How much heat or noise does this fitting generate during continuous operation?
The fitting itself produces no heat or noise; it is a passive brass component that simply secures the tubing within the liquid-cooling loop.
What tubing size and thread standard must I already have for this fitting to work?
You need 16 mm outer-diameter PETG hard tube and a component with a G1/4 female thread to accept the fitting.
