Our comprehensive range includes both standard and the enhanced\u00a0Fisher ENVIRO-SEAL\u2122 live-loaded packing systems<\/strong>, which are engineered to deliver exceptional stem sealing capabilities. These systems are easy to install in your existing valves and help conserve valuable process fluid while protecting against the emission of hazardous fluids. The live-loading mechanism ensures a constant, optimal load on the packing material over its lifespan, significantly reducing the need for maintenance adjustments and downtime.<\/span><\/p>

Whether you require PTFE for general service or specialized materials like Graphite ULF for higher temperatures, our kits help you achieve sealing performance that can keep emissions well below the 100 ppm requirement set by the U.S. Environmental Protection Agency (EPA).<\/span><\/p>
