EK-Cryofuel Loop Superflush is a solution made to flush out manufacturing residues, impurities, and leftover chemicals. It can be used either as a stand-alone solution or after the EK-CryoFuel Loop Cleaner. Stand-alone - prepares a new, unused loop for a new coolant and extends its life, improves stability, and reduces soft tube yellowing. Follow up - after using EK-CryoFuel Loop Cleaner to clean gunk and old coolant, Superflush is used to pick up and rinse any residue chemicals left from the cleaner. The premix comes in a 1-liter bottle and is ready to use. This solution does not act as a corrosive inhibitor or biocide for coolants. Compatible with all EK soft and hard tubing. Model: 3831109897706
