Water Cooling Loop Cleaning Kit

This all-in-one kit simplifies the rebuilding of an existing water cooling loop. It contains Rad Clean, System Reboot, and PrimoPrep solutions to flush residue, remove dye remnants, and prepare the system for new coolant. The water-based formulas are non-toxic and safe for plastics, rubbers, and acrylic components. It removes the guesswork from changing over coolant in a custom system.

For Copper and Brass Loops Only

This kit suits builders servicing a loop made from copper or brass components who need to strip old fluid and film before a refill. It is not compatible with aluminium watercooling parts, so systems containing aluminium radiators or blocks should look at a different cleaning method. The included Rad Clean bottle holds 2oz of radiator flush solution. Users requiring a larger volume of cleaner will need additional bottles.

Rad Clean 2oz Bottle Included

The supplied Rad Clean bottle contains 2oz of fluid designed to scrub the inside of radiators and flush out bits and chemical film. This specific volume determines how many radiators or how large a loop can be treated in a single pass. Check your total loop capacity against this amount to decide if one kit is sufficient for your flush.
