333Q0001906 Frick #11ST Refrigeration Oil - 55 Gallons

A premium version of FRICK #11 refrigeration oil, blended to condition O-rings in ammonia systems that have operated on mineral oils. This product is also compatible with mineral oils and equipment designed for mineral oils. The seal treatment (ST) in the formulation reduces the risk of seal leakage caused by O-ring shrinkage in retrofit of systems that have operated on mineral oils. FRICK #11ST refrigeration oil is recommended for evaporator temps of -70°F (-57C) and above, and meets the requirements for a lubricant where there is no possibility of food contact (H2) in and around food processing areas.
