They are available in a large array of colors, and can be applied to a wide variety of sizes & configurations, to allow ease of installation. We also supply several grades of Dow Corning silicone lubricants, that are applied to the surface of the seals and controlled by strict proportioning of the water & lubricant, to ease the installation of the seal.
