These are genuine Gardner Denver belts for Gardner Denver air compressors. These are a must to keep the warranty on your machine valid. Using a non-original Gardner Denver belt will void any warranty on your machine. These genuine belts are long lasting and of best quality.
Using these belts on out of warranty machines will also make sure the unit stays operational and no damage is done to it… a belt that fails can be dangerous even with a protective cage! Losing an eye is not repairable!
