Flat rubber gaskets to go under your antenna where it presses on the metal surface. Fits around the normal NMO body mount and seals out water and protects the car surface. Most antennas will use this style gasket to compress when tightened.

Made of Premium Quality Diecut Neoprene, these are ready to last having a Durometer rating of 60 Duro (+/- 5) Shore A. Neoprene has a good chemical stability and flexibility over a wide range of temperatures and is also resistant to oil, heat, light and oxidation. Moderately resistant to ozone and UV light. This works better on a vehicle's surface and the 60 Duro rating still allows it to slightly conform to weather pitting of the paint and irregular conditions of the car's body surface better!
