ARMOR 3500 - Our Highest Grade Industrial Tire Sealant Designed for The Most Hazardous & Extreme Operating Environments, 5-Gallon Pail with Pump

This Multi Seal is amazing. Used it for our forklift that ran over a board with 3 large nails. Used it for our tractor tire that was punctured. Easy to use, excellent product!

OMG, this Multi sealer really sucks. I can't go and see my favorite tire dealer any more!(As much, there are some really big holes on sidewalls this will not seal) Put 32oz in trailer tires or 40oz in light truck tires and you won't have the same relationship you had in the past with your tire dealer. We were literally buying 60 trailer tires a year, patching and plugging so many more. Would go through 2-3 sets of truck tires per truck as well. So many tires were being retired early with good tread, it was ridiculous. Now I'm actually saving money on tires this year. 3 months into the construction season and not one trip to the tire dealer. They even sent me an email thinking I was upset at them because they haven't seen us this year. Get the pump for the 5 gal pail, you'll need it. 8oz per pump is installed each full stroke. Not 1oz like the little pumps on the green stuff,(which never really worked for us). Easy to assemble pump and to use. Save time and a lot of money. Pulled a 16 penny nail from a trailer tire, pumped 40oz in a rear dually tire, told driver to go. Actually watched a 6 to 8 inch stream shoot from the tire as he drove off, then nothing. Both of us couldn't believe how fast it works. Just like the video on their site. After use have a spare bucket and seal lid on unused portion. Rinse pump with water and place assembled pump on spare bucket. Now I have more time to spend on that honey do list. Thanks a lot Multi Seal!

Bottom line up front: The pump was worth the purchase because it worked way better than any homemade solution I could come up with; however there were a special adapter and repairs to the coupler needed before I could do any install of fluid. Also, the pump shaft leaked a good bit and started to seize during install.Real quick, the stem on my JD 3032e tires (and my lawn tractor tires as well) had a shoulder that kept the quick connect from locking on. I purchased a 2 1/2 inch Tire Valve Extension from NAPA, part 90-312. You will need proper valve stem removal tool. Remove the extra long valve core from the extension and take a small drill and ream out the small plastic piece just to the inner diameter of the extension that holds the far end of the core. Do not remove completely. Leave the small o ring on top of the plastic piece it will help seal when you are installing fluid. Once you are ready, check tires inflated to at least 15 psi, remove valve core from stem, install extension hand tight. Install connector and start pumping.Quick connect issue. The quick connect is designed to slip over the valve stem and clamp on. My quick connect was not functioning. You can check by connecting to the valve stem on the bucket lid and pumping. The problem was that the quick connect was not assembled properly. If you look at the end where it connects to the valve stem, there is a small (~1mm) ring that holds it together around the center piece. Take a small pick or very small flat blade screw driver and pry it out carefully, just lift out one end and it should ring out easily without deforming. The inner and outer part slide apart exposing the spring, ring and 2 shoulder pieces. The ring and spring go under the shoulders when its facing up with the ring holding the spring back. Then reassemble into the coupling and replace the small spring clip.Also had issue while pumping fluid it quit going up all the way and some liquid was coming out around the shaft. I will disassemble and clean to see what happened there. I was able to complete the last couple tires with half strokes.I found the problem with the pump, it was the o ring on the piston was all chewed up. I found one at my local Ac3 hardware store, they are also available on Amazon Danco 35741w Oring, 7/8 X 1-1/8 X 1/8 aka Danco D 27.

I loaded my rear tractor tires (R-14s) with RV antifreeze and added the recommended quantity of this sealant. One of the tires has a puncture from a mesquite thorn in one of the lugs. When I park the tractor with the puncture at the six-o'clock position, it appears to seal temporarily. But, as soon as the wheel rotates, air escapes. So I'm not impressed with the sealants performance when weighed against the manufacturer's claim...but that's my experience, yours may be different.

I run a roll off trailer and the dump here was punchering at least 2 tires a month... Not anymore, not only did this seal my spare that came back from the shop leaking, but it also sealed a tire with a bad leak that had been driven flat more than I will admit to. But the real kicker is the tire I had driven around flat had a bunch of pin holes in the sidewall, so I took it off the trailer and laid it down and this stuff has kept it at 100psi+ for months. That's right, it sealed the holes in the sidewall, I'm sure that isn't a "recommended use" and I haven't reinstalled it but it's abs holding air.

I used this product to seal leaks on a boom lift tire that had a rusty rim around the beade.Last resort before buying a new rim.Product sealed the leaks, works very well!

I used Gempler's Ultraseal Extreme Heavy-Duty Grade Tire Sealant before this product. The two could not be farther apart. Gempler's sealed everything up to 3/16. This does not seal a pin hole up to 3/16. It just leaks out and makes a mess.I have had to change so many inner tubes since using MULTI SEAL PRO HD 2500.With Gempler's when i did change an inner tube, such as changing the tire, I would find hundreds of places on the tube where it stopped the leak.With MULTI SEAL PRO HD 2500 --- I replace the tube often due to leaks, and I pull out the tube to find a liquid mess inside the tire. It seems to pass from the tube to the tire without sealing the leak.

This product sealed the tire leaks of several off road vehicles that other products failed to seal. This stuff works every time.
