Tubing for Custom Loops

PrimoChill PrimoFlex LRT tubing is made for builders assembling custom water-cooling loops. The 7/16 inch inner diameter and 5/8 inch outer diameter match common compression fittings and barb-and-clamp setups. It ships in a 10 foot length bundled with system preparation fluid and coolant. The purple colour adds a distinct visual accent to the loop.

Compatibility and Limitations

This tubing suits enthusiasts who want a flexible, USA-made option with a long track record in the hobby. It is not for users who require tubing certified for alcohols, ethylene glycol or other aggressive chemicals, as those fluids are explicitly prohibited. Builders who prefer rigid acrylic or PETG runs should look elsewhere.

Build Integration

The 3/32 inch wall thickness gives enough structure to hold shape while remaining pliable for tight routing around components. It works with standard 7/16 by 5/8 fittings, though strict-tolerance brands such as Bitspowr and Lamptron have shown minor fit issues. Dyed coolants will stain the material, so clear fluids preserve the original purple hue.

Questions about this item

Which fittings match the 7/16in ID and 5/8in OD of this tubing?

Use 7/16in x 5/8in compression fittings or 7/16in barbs with 5/8in clamps for a secure seal.

Will the Advanced LRT formula work with my existing closed-loop cooler components?

It is formulated for broad closed-loop compatibility, though strict-tolerance brands such as Bitspower or Lamptron may show minor fit issues.

How can I confirm the tubing is performing correctly after installation?

Check for leaks at every fitting, verify coolant flows without kinks, and monitor for staining if dyed fluid is used.
