I an somewhat superstitious, afraid to think how many flats I have not had with Orange Seal Endurance or making any boasts about how long it has been since I had a flat…
As an aside, I must relate my first amusing efforts at getting sealant into my tires. I bought some fancy rig which was supposed to thread onto the valve with a big syringe injector. They must have known how much sealant would end up on the floor and require the purchase of more sealant! Since then I use a tapered Monoject syringe and just pour it in.

I just use a 60ml syringe with a Leur lock and a little bit of plastic tubing, For the most part, it just works like a funnel with a convenient volume measurement. If I absolutely have to, I can use the rubber-tipped plunger, but it is usually easier not to do it that way.

It does not work for Panaracer sealant properly, as it filters out all the walnut shell particles. For that stuff, even their conical screw-on cap doesn't work. You have to pour it in the tire directly, after breaking the rim/tire seal, which is why I decided to try Orange Seal.

That’s not true, as I use a small, 3oz sealant bottle (either a Bontrager or Stan’s, I forget which) with the conical top cut just wide enough to slide over the valve stem, and simply squirt the sealant in. It’s very simple and easy, and of course there is no filter in it, so any sealant goes right through, no problem.

You went to the trouble of putting what I was referring to, which is Panaracer's sealant, in square brackets, yet you invalidly infer becuase it works for Bontrager or Stan's, it will work for Panaracer. Do either Bontrager or Stan's use walnut shell particles? Panaracer does, and some of the particles are significantly wider than the bore of the conical top.

Here is what the Panaracer stuff looks like. The largest chunks are coating the side of the bottle, but even what is on the postcard is fairly marco-granular.

Stan's. Works for me so far.

chaadster

No, you misunderstood.

I use an old Bontrager (or maybe it’s Stan’s) 3oz bottle to squirt Panaracer SealSmart.

The use of brackets inside a quote is to clarify a referent, in this case, to clarify your phrase, “that stuff,” refers to Panaracer SealSmart.

Further, it should be obvious that the “bore” of the conical top is not only variable based on where you cut it, but also since I said I slid it over the valve stem, that the “bore” is obviously larger than any particle in the sealant.

Polaris OBark

It isn't larger in diameter than the largest particles in Panaracer's sealant.

Presta valves are 6mm (~ 1/4 inch) in outside diameter, so the "bore" has to be bigger than that to slip over it. Panaracer sealant has particles that won't fit through a bore that big? The particles in the photo look much smaller than that.

chaadster

Your contention is that Panaracer makes a sealant with particles too big to fit through a valve stem?

That’s news to me, and I’ve used quite a bit of it.

But, just because I’m surprised doesn’t mean it’s not true. Maybe there’s batch variation, and I’ve just been lucky.

It would be silly for Panaracer and Herse not mention, as Stan’s do for their Race sealant, that it needs to be poured directly into the tire.

Interestingly, when I just went to see if Panaracer or Herse specified a maximum particulate size, I found a pic on the Herse blog, in a post announcing the newly releases SealSmart, of exactly the filling technique I use with their Panaracer SealSmart:



Notice the conical top is cut wide enough to fit over the valve stem.

In the picture, the nozzle is going inside the sleeve of the valve. When you do it that way, yes, the larger particles in Panaracer's sealant form a mesh and then the conical dispenser starts to clog.

The last bottle I bought from Rene Herse didn't come with the conical dispenser, FWIW. I can only speculate why.

For valves like mine, the main concern is that they will clog at the end inside the rim.

Conical valve sleeve bore mesh.

Awesome.

I like Monoject syringes because they have a tapered curved tip that seals nicely into the valve.

^ That's the bottles of Stan's I got also.

It worked a treat just squeezing the sealant in via the valve stem (valve removed of course). For my full-disc TT wheel with only a small valve hole cut-out, I used a syringe and thin bit of tubing to "inject" via the valve stem.

You know what? I went to a dollar store and found a set of squeeze bottles with tips the fit inside the valve stem with the core removed. The bottles are semi transparent so it is easy to measure out the amount of sealant needed. A gentle squeeze and the sealant flows into the tire though the valve stem. Low tech, but very effective. Haven't clogged a valve stem yet. the slow flow does the trick
