SPEC HIB 900 is a one-part Universal Add Pak that incorporates cutting-edge inhibitor technology to provide a reasonably priced antifreeze additive package. SPEC HIB 900 possesses several advantages associated with organic long life add paks, including lower dissolved solids levels and the absence of sometimes objectionable add pak components. SPEC HIB 900 is a non-silicate, non-phosphate, non-nitrate, non-nitrite one-part inhibitor package. It contains additives to minimize hot surface scaling while also preventing heat transfer surface fouling due to minor oil leakage.

This inhibitor package produces antifreeze that meets ASTM D 3306 specification for light-duty and automotive and ASTM D 4985 specification for both heavy-duty and diesel engines. SPEC HIB 900 can be used effectively with either ethylene or propylene glycol.

This Universal Add Pak can also be used with either virgin or high-quality reclaimed glycol from distillation units, reverse-ismosis membranes, or most flocculation/filtration systems. Available in 5 gallon pails and 55 gallon drums.
