Loader nipples enable grease guns to suction-load grease from bulk containers. Also called loader couplers, they attach to grease guns solely for this purpose. They are useful in industrial settings that use a high volume of grease where it is more practical, cost-effective, and environmentally sensitive to use barrels of lubrication rather than individual cartridges.

Grease gun holders mount to equipment or machinery to hold a grease gun for quick access. These metal brackets encircle the barrel of the grease gun to keep it secure and off the floor when not in use.

Bearing grease packers are hand-operated devices that help repack fresh grease into bearings while removing old grease. They reduce waste, mess, and eliminate the need to clean bearings prior to packing.
