Dielectric Grease Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Super Lube is the best-performing dielectric grease brand in July 2026, moving 15,000 units across 3 ASINs for 31.9% of Top 10 volume. Lucas Oil follows with 13,000 units (27.7%), ahead of Permatex on 6,000 units (12.8%).

With 6 brands splitting the Top 10 and 72.3% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $9.00 to $13.60, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, one ASIN forced its way in: B000DZFUPC booked 2K units at $5.48, with ▲ 100.0% MoM change. On the growth side, B000HBNV58 leads positive momentum with ▲ 400.0% MoM growth on 1K units, with B0044NI2M2 close behind at ▲ 250.0% MoM on 700 units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
