The new Eiszapfen PRO HardTube fittings from Alphacool are a further development of the well-known, previous Eiszapfen. When developing the fittings, Alphacool concentrated on one particular problem: the deformation of PETG hard tubes at high temperatures. These can deform at 60 ° C. Although such a temperature is rarely reached, it can still occur. The Eiszapfen PRO prevents this problem from the outset and keeps the tubes in position.

Deformation is prevented by the new nylon inserts on the inside which stabilizes the hard tubes. Furthermore, the fitting still has an O-ring and a compression seal. However, the contact area is much larger than with normal O-rings, which ensures a better hold. Through the use and the compression seal in the screw connection, the tube is reinforced from the inside and outside.

The HardTube does not slip even under higher loads. Alphacool has tested the tensile strength of up to over 8kg! So there is no need to worry about this.

Please Note: Not recomended for use with Bitspower brand tubing.
