This is a Single Use Packet of Silicone Dielectric Grease. We also offer bulk packs: 50, 500, 2500, 5000 pieces, click on Related tab for larger packs. Great to keep some in the truck to be sure and 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.
