Palmetto Packings-631A-13470235 1347AF Series Synthetic with PTFE & Lube Compression Packing Seal, White, 1/2" Square, 10' Length

Like it to be longer

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!

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.

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

Excellent!

Worked as expected

Quality at a good price. Fast delivery
