Rigid PETG Tubing for Custom Loops

PrimoChill 12mm ID 16mm OD rigid PETG tube is supplied in a pack of six 30in lengths for building custom watercooling circuits. The material cuts and bends with basic tools, making it accessible for first-time builders. Its smooth inner surface resists particulate buildup and helps keep coolant clear over time.

Suited for DIY Builders Needing Forgiving Material

This tubing suits enthusiasts who want to shape rigid runs without specialised heating equipment or complex fitting inventories. Builders who require tighter bend radii than PETG allows, or who plan to use alcohol-based or ethylene-glycol coolants, should consider alternative tubing types.

Fits 16mm OD Compression Fittings

Each 30in piece connects directly to 16mm OD rigid compression fittings, reducing the need for 90 degree rotaries or excessive adapters. The 2mm wall thickness provides structural rigidity for straight sections while still allowing measured bends. Six pieces give enough length for multiple runs with spare material for test fits.

Questions about this item

Do I need 16 mm OD rigid compression fittings to connect these 12 mm ID tubes?

Yes, the 16 mm outer diameter requires matching 16 mm OD rigid compression fittings for a secure seal.

Can I mix these 16 mm OD PETG tubes with older 12 mm OD acrylic runs in the same loop?

No, the 16 mm OD tubes need 16 mm fittings while 12 mm OD tubes need 12 mm fittings; they cannot share the same fitting size.

How can I confirm the 30 inch tubes are seated correctly after bending and cutting?

Check that each tube sits fully into the 16 mm compression fitting collar with no visible gap and that coolant flows without leaks at the joints.
