NOTICE
Risk of using the wrong type of glycol. Can cause piping damage, coolant fluid leaks, and catastrophic and
expensive building and equipment damage.
Do not use automotive antifreeze as it contains chemicals that can damage the piping system.
Typical inhibited formula ethylene glycol and propylene glycol are supplied with corrosion inhibitors and do
not contain a silicone anti-leak formula. Commercial ethylene glycol and propylene glycol, when pure, are
generally less corrosive to the common metals of construction than water itself. Aqueous solutions of these
glycols, however, assume the corrosivity of the water from which they are prepared and may become
increasingly corrosive with use when not properly inhibited.
