PrimoChill 5/8in Rigid PETG Tube Clear

This PrimoChill 5/8in rigid PETG tubing suits performance enthusiasts and case modders building custom watercooling loops. The clear tubing enables tight bends and straight runs while reducing the need for excessive compression fittings or 90 degree angle rotaries. It is made in the USA with thicker walls for safer operation and is environmentally responsible, safe, and non-toxic. The pack contains six pieces of 30 inch tube.

Before ordering check fitting compatibility

Verify that your existing loop uses 5/8in OD rigid fittings matching the tubing outer diameter of 5/8in with a tolerance of ±.005 and an inner diameter of 1/2in ±.005. Ensure you have the tools and technique to measure, cut, and bend PETG tubing to the required shapes. Confirm that your coolant choice and flow rates are compatible with PETG material to avoid appearance changes.

Upgrades from acrylic tubing

This PETG tubing replaces acrylic tubing by offering superior strength and easier bending without the same risk of cracking. The thicker wall provides safer operation under pressure. The jump is worth it for builders who want tighter bends, fewer specialised fittings, and a more forgiving installation process while keeping a clear aesthetic.

Questions about this item

What comes in the box and which fittings must be purchased separately?

The package contains six clear PETG tubes, each 30in long with a 5/8in outer diameter and 1/2in inner diameter. You will need 5/8in OD rigid fittings to complete the loop.

Which tube size matches the 5/8in OD specification shown in the listing?

The listed tubes have a 5/8in outer diameter, 1/2in inner diameter and 1/16in wall thickness, so choose 5/8in OD rigid fittings for a direct fit.

What does the 5/8in OD figure mean once the tubing is installed in a custom loop?

It sets the required fitting size; the 1/2in inner diameter and 1/16in wall give a rigid run that holds tight bends without extra 90-degree rotaries.
