This Palmetto style 1585 carbon compression packing seal with a graphite coating protects pumps and valves from fluid leaks in high-speed,
This Palmetto style 1585 carbon compression packing seal with a graphite coating protects pumps and valves from fluid leaks in high-speed, high-temperature applications. The interwoven braided packing seal is made of 95-percent assay carbon polyacrylonitrile (PAN) staple yarn, which absorbs and retains wet and dry lubricant for improved sealing and reduced friction and wear on the shaft or stem. It also exhibits high tensile strength, thermal conductivity, and resistance to abrasive media and harsh chemicals. Its low coefficient of friction reduces wear on the shaft. The carbon fibers are coated with graphite to increase the transfer of frictional heat away from the shaft, permitting high shaft speeds and reducing the chance of leakage.
This packing seal is compatible with media in a wide pH range of 1-14, except for strong oxidizers in the 1-2 pH range, such as oleum, fluorine, and fuming nitric acid. It has a maximum pressure limit of 3,500 pounds per square inch (psi), a pressure-velocity (PV) factor of 800,000, and a shaft speed of 4,400 feet per minute (fpm). This high temperature packing seal operates to a maximum temperature of 1,200 degrees F (650 degrees C) in steam and 650 degrees F (343 degrees C) in oxidizing atmospheres. Style 1585 is suitable for use in high-speed pumps, furnace gaskets, blowers, driers, high-temperature valves, and as anti-extrusion rings with style 4010AF for extended life in boiler feed, condensate pumps, and turbines.

Rope seals provide a pressure seal to help retain fluids and gases in a wide variety of commercial and industrial applications. They have a round, square, or rectangular cross section, and come in various braided designs including braid-over-braid, braid-over-core, laminated, twisted, or interwoven. Rope seals can be manufactured from a single material or a combination of materials that suit specific pressure, temperature, speed, and chemical applications. Some rope seals are impregnated with lubricant and have reinforced cores for improved performance in specific environments, such as extremely high temperatures. They can be used to create a static seal in fixed or slow-moving applications like expansion joints, doors, and valves, or a dynamic seal in equipment with reciprocating, rotating, or oscillating movement like centrifugal pumps, rotating stems, and blowers. Rope seals come in uncut lengths on spools or as precut molded rings. They are used in numerous industries including agriculture, oil and gas, automotive, aerospace, construction, and consumer goods.
Palmetto Inc. manufactures packing products for pumps and valves, such as compression packing seals, packing tools, gasket sheets, and fillers. The company, founded in 1872, is headquartered in Denton, MD.
