Chemola™ Desco Green Wellhead Packing is a proprietary packing formulation that has been developed primarily for the energizing of elastomer seals in crossover bushings in wellhead applications. It has also been used quite successfully as a packing energizer in blowout preventers. A blend of silicone oils and inert synthetic fibers allows for lubrication and the necessary bridging capabilities.
