This is a bulk pack of (50) Single Use Packets of Silicone Dielectric Grease. We also offer larger bulk packs: 500, 2500, 5000 pieces, click on Related tab for larger packs. Apply to plow electrical connections when mounting or removing plow. Every manufacturer recommends it! Great for trailer plugs and light bulb sockets too. Big tubes are great, and we sell those too under "Related Items" but a big tube belongs in the shop, toolbox, or garage. These you can keep in the truck, give out to your customers, include with a product you sell, leave on the front counter as an impulse buy. We sell them for $1 each here.
