Alphacool AlphaTube HF 5/3mm Tubing

This 1 m length of PVC tubing has an outer diameter of 5 mm and an inner diameter of 3 mm. It is designed to connect water cooling components such as pumps, radiators and blocks. The Ultra Clear finish suits builds that want a transparent look. Builders who need coloured or UV-reactive hose should choose a different variant.

Flexible PVC With 65-70 A-Shore Hardness

The material balances easy routing with resistance to kinking at tighter bends. Rated for a working pressure of 2 bar and a burst pressure of 8 bar, it handles typical loop pressures. Operating temperature range spans -10 °C to 80 °C. The retail box carries part reference 18620.

Upgrade From Opaque Or Stiffer Hose

Replacing cloudy or rigid tubing improves flow visibility and simplifies tight runs. The jump is worth it when a clear aesthetic matters and the 5/3 mm size matches existing fittings. Loops requiring larger bore or different material will not fit this hose.

Questions about this item

What inner and outer diameter does the AlphaTube HF 5/3 mm tubing use?

The tube has a 3 mm inner diameter and a 5 mm outer diameter, matching standard 5/3 mm compression fittings.

What is the minimum bend radius before the PVC tube kinks?

With a 65-70 A-Shore hardness the hose stays flexible for tight bends yet resists kinking; warm it briefly in hot water if a very sharp corner is needed.

How do you secure the tubing to barbs or compression fittings without leaks?

Slide the 3 mm bore over the barb, then tighten the compression nut by hand plus a quarter turn with a spanner — overtightening crushes the PVC and causes seepage.
