Profile: Lutz Sales supplies rubber o-rings, seals and gaskets. We are a licensed DuPont Vitonr distributor and stock Vitonr, Buna-N, silicone, Teflon and many other materials. We are accredited with ISO 9001:2000 quality systems. We provide PTFE (often called Teflon®) industrial coatings for all our seals. PTFE industrial coatings spray on like paint and bake to a tough, inert finish. PTFE is available in a large array of colors and can be applied to a wide variety of sizes and configurations to allow ease of installation. We offer several grades of Dow Corning silicone lubricants that are applied to the surface of the seals and controlled by strict proportioning of the water and lubricant to significantly ease the installation of the seal.
