Available in ISO grades 46, 68 , 100 and 150. Airco Glo-Lubes are standard PAGs, pre-treated with Glo-Leak® UV tracer fluid. They are handy to use when topping up a system which has already been treated with Glo-Leak®, and also when refilling with oil after a system flush and/or a change of compressor.
