This Palmetto style 1607 flax compression packing seal with graphite and a petroleum and wax-based lubricant protects pumps and valves from fluid leaks in general service applications. The interwoven braided packing seal is made of premium-grade flax fiber for high tensile strength. The flax fibers are coated with graphite to increase the transfer of frictional heat away from the shaft, keeping the stuffing box cool and reducing the chance of leakage. A petroleum and wax-based lubricant improves break-in time, further reduces frictional heat, and prevents the packing from spinning with the shaft or stem, reducing the chance of scoring and wear.
This packing seal is compatible with media in the pH range of 6-8 (brines, cold water, and oils), has a maximum pressure limit of 250 pounds per square inch (psi), and a shaft speed of 2,500 feet per minute (fpm). It operates to a maximum temperature of 210 degrees F (98 degrees C). Style 1607 is suitable for use in general service applications such as rotary and reciprocating shafts, rams, and plungers, among others.

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.
