“Fat Boys” silicone shock absorbing o-rings
quantity 8
GMK 0110


"Fat Boys" are shock absorbing o-rings. These 3mm ID silicone o-rings are perfect for use with 3mm or 4-40/5-40  screws to hold your fuel tank to your vehicle, for extra shock and vibration damping. Properly damping the vibration to your fuel tank can help to stop the fuel from foaming. You can also use these anywhere you need shock absorbing isolation on your vehicle.
