AP3 Grease Full Form and Meaning
AP3 = All-Purpose grease of NLGI consistency grade 3. The NLGI number (set by the National Lubricating Grease Institute) describes how firm the grease is, from 000 (almost fluid) to 6 (block-hard). Grade 3 is a firm grease that stays put on pins, threads and exposed bearings without slumping in heat — the reason it is the default choice on Indian construction sites over softer NLGI 2 greases for exposed points.
AP3 Grease Uses
