A complete gearbox lubricant. Including bearing, air-seal and gear grease. The gear grease is a high viscosity lube designed to stick to the gears even as they are turning. The bearing grease is specially designed to reduce friction on the bearings. The air seal grease is designed to be used in the cylinder, on the piston head, and inside the air seal nozzle to seal up any possible air leaks and create the perfect seal for maximum efficiency. Ensure your Gel Blaster works smooth and has better performance. Essential accessories after upgrading or repairing the gearbox.
