Palmetto 1382 Series Expanded PTFE with Graphite Compression Packing Seal Dull Black 1/8 Square 5 Length

This Palmetto style 1382 expanded PTFE and graphite compression packing seal with an inert lubricant s rotating pumps and s from fluid leaks in chemical or abrasive slurry applications. The interwoven braided packing seal combines yarns made of expanded polytetrafluoroethylene (ePTFE) and graphite to provide a seal that withstands harsh chemicals and handles high shaft speeds. ePTFE is a strong flexible material that exhibits the same characteristics as polytetrafluoroethylene (PTFE) such as low friction and resistance to harsh chemicals but has a more porous conformable structure that accepts lubricant better and helps reduce leak-off in applications with irregular surfaces and s. Graphite yarn transfers heat away from the shaft to prevent glazing and scoring extending the packing and sleeve life. It handles high temperatures high shaft speeds and exhibits a low coefficient of friction for reduced shaft wear. An inert lubricant improves break-in time reduces frictional heat and prevents the packing from spinning with the shaft or stem reducing the chance of wear and extending the packing life. This packing seal is compatible with media in the pH range of 0-14 except for strong oxidizers in the 0-2 pH range such as oleum fluorine and fuming nitric acid. It has a pressure limit of 1 900 pounds per square inch (psi) and a shaft speed rating of 3 800 feet per minute (fpm). It operates across a wide temperature range from -400 to degrees F (-240 to 288 degrees C). Style 1382 is suitable for applications such as sludge paper asphalt pumps and chemical and mining pumps.Rope seals provide a pressure seal to help retain fluids and gases in a wide variety of and industrial applications. They have a round square or rectangular cross section and come in various braided designs including braid-over-braid braid-over- 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 s 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 s 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 s such as compression packing seals packing tools gasket sheets and fillers. The company founded in 1872 is headquartered in Denton MD.
