This Palmetto style 1347AF PTFE-impregnated synthetic compression packing seal with a petroleum-based lubricant protects pumps and valves from fluid leaks in general service applications. The interwoven braided packing seal is made of soft, flexible acrylic (Syn-Tex) yarn impregnated with a fifty-percent dispersion of virgin polytetrafluoroethylene (PTFE). PTFE fills gaps in the braid to improve sealing and protect the packing from harsh chemicals, including solvents, acids, bases, and strong oxidizers. Its low coefficient of friction reduces shaft wear by minimizing drag and heat buildup between the packing and the shaft or stem. The packing is saturated with a petroleum-based break-in lubricant that provides lubrication and sealing at initial start up to prevent overheating and glazing. It also reduces the need for frequent adjustments during break-in. The packing is non-contaminating and non-staining. This packing seal is compatible with media in the pH range of 2-12, has a maximum pressure limit of 1,500 pounds per square inch (psi), a pressure-velocity (PV) factor of 335,000, and a shaft speed of 2,300 feet per minute (fpm). It operates at temperatures from -10 to 450 degrees F (-23 to 232 degrees C). Style 1347AF is suitable for use in equipment such as centrifugal pumps, mixers, blenders, agitators, and knife gate valves, among others.Specifications pH range 2-12 Pressure limit 1,500 psi (103.5 bar) PV factor 335,000 Shaft speed 2,300 fpm (11.7 m/s)Temperature range -10 to 450 degrees F (-23 to 232 degrees C)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.

Absolutely amazing, should have changed over from flax yarn packing long ago!
Absolutely amazing. I am not a fluid engineer, just a beekeeper with a 60 gallon agitator tank with a shaft through the bottom that we use a few times each year to mix sugar syrup to feed bees in the late fall. We mix hundreds and hundreds of gallons, previously I had used old style flax based valve gland seal but even with careful adjustment during break-in it would eventually leak like a sieve. The drips coming through the shaft seal would hit the spinning bottom flywheel and spray out across the floor, leaving a sticky mess covering everything. As we do not require food grade, I received some advice to try the Palmetto 1347A PTFE lubricated packing. I installed it today and ran the agitator for hours, no visible leakage through the stuffing box, not even a drip on the floor! I can't believe I waited all of these years to change direction on packing, this stuff appears to be a serious improvement for our hundred year old agitator tank and stuffing box!

Reciprocating shaft pump seal
I use it on a 5/8" X 4"stroke slow reciprocating pump shaft pumping 135 degree water at up to 150 lbs pressure. No problems. Yes I let it leak 1-2 drips a minute out of stupidity or habit.

Teflon flax shaft seal
Very high quality materials on a spool that makes the seal material of the correct diameter rather than forming it upon installation.
