PrimoChill Water Cooling Cleaning Prep Kit New System diy cooling

SKU CH-AZGN-JMNZJ

Complete kit flushes radiators, cleans loops, and balances pH for new copper or brass cooling systems

  • TypeCPU Block
  • Complete new-loop cleaning kit removes factory residue
  • Radiator flush eliminates manufacturing film and debris
  • System prep clears dust from tubing and blocks
  • PrimoPrep balances pH for mixed-metal loops
  • Water-based, non-toxic formula safe for copper and brass

New Loop Cleaning Kit

This all-in-one kit is designed for builders assembling a brand-new custom water cooling loop. It contains three dedicated solutions to remove manufacturing residues from radiators, tubing, blocks and other components before the system is filled with coolant. The kit targets anyone who wants a clean, low-maintenance start without sourcing separate chemicals.

Replaces Ad-Hoc Flushing Methods

The kit replaces improvised cleaning routines such as vinegar rinses, distilled water loops or single-purpose cleaners that may miss specific contaminants. The jump is worth it when you are commissioning a fresh loop with new radiators and blocks and want a single, sequential process that addresses metal films, debris and pH balance in one package. It is not for loops that are already running or for maintenance flushes on existing coolant.

Copper and Brass Compatibility Only

The chemicals are formulated for copper and brass components and are explicitly not compatible with aluminium water cooling parts. Using the kit in a loop containing aluminium radiators or blocks risks chemical damage and corrosion. Builders planning mixed-metal loops that include aluminium must choose a different preparation method.

Questions about this item

What radiator sizes and tubing diameters does the kit clean?

The kit works with any copper or brass radiator, block and tubing combination; it is not compatible with aluminium water-cooling components.

In what order should Rad Clean, Sys Prep and PrimoPrep be run?

Flush radiators with Rad Clean first, then circulate Sys Prep through the whole loop, and finish with PrimoPrep to balance pH before adding coolant.

Does the kit need to be reapplied after the initial fill?

No, the three-step process is designed for a one-time new-loop preparation; ongoing maintenance only requires your chosen coolant.
