PrimoChill PrimoFlex LRT Tubing 7/16in ID 5/8in OD 10ft Purple

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.
