Rigid PETG HardTube 16/12mm

This clear PETG tube is a rigid alternative to flexible soft tubing for custom liquid-cooling loops. Its 16 mm outer and 12 mm inner diameters suit builders who want precise, straight runs and a clean aesthetic. It is sold new in a 500 mm length for cutting to exact fit.

Thermals noise and power

The tube itself generates no heat, noise or electrical draw because it is a passive conduit. Thermal performance depends entirely on the coolant, radiator and pump you pair with it. Proper bending and fitting eliminate flow restriction that could raise loop temperatures.

Bundled accessories and software

The package contains one 500 mm clear tube only; no bending cord, heat gun, bending tool or specialised 16 mm hardline fittings are included. You must source those separately to shape the tube and secure leak-free connections. Using standard compression or barb fittings will cause cracking and leaks.

Questions about this item

How do I install the 16mm PETG hard tube and what is the common mistake?

Cut the 500mm tube to length, chamfer the ends, then heat evenly with a heat gun while inserting a bending cord to form bends; the frequent error is using standard compression or barb fittings instead of dedicated 16mm hardline fittings, which causes cracking and leaks.

What maintenance or replacement will the PETG tube need later?

Inspect the clear 16/12mm tube periodically for clouding, plasticiser buildup or micro-cracks near bends; replace the 500mm section if discolouration appears or if a fitting is re-seated and the tube end shows stress whitening.

What limit appears first during sustained use of the hard tube?

The PETG material softens above its glass-transition temperature, so continuous coolant temperatures approaching that point will cause the 16mm tube to lose rigidity and deform before any fitting failure occurs.
