Our Anti-Static Ground Wire should be used when attaching the Hose Kit to the J-7 Aerosol Can-Emitor to prevent sparks and reduce the risk of fire from static electricity that can be generated by the movement and flow of flammable liquids and propellants. Measuring approximately 6 feet long, our Anti-Static Ground Wire is made of flexible copper and features an industrial alligator clip and a ground lug for easy attachment.
