Which tubeless sealant?

I’ve read on another forum that some people are doing a little bit of Orange seal, letting it dry out, and then adding Stans. The theory is that the Orange seal provides an initial coating inside the tire.

Is anyone trying these combo techniques?

Personally, I’ve had good luck with Stans regular on my gravel bike. I went road tubeless (GP5000TL + Orange Seal) in October 2019 but I haven’t had a single flat yet.

I run tubeless on both my Commuter (32mm slicks) and my Road Bike (25mm tires) I started with Stans but it never held well at road tire pressures (~60psi on the commuter, 80 on the road) Switched to Orange which worked better. My local shop stopped carrying Orange Seal and I went to Stans Race which also works well at higher pressures. That said I still run into issues if the hole is big enough.

I worry about availability and compatibility between sealants more than slight improvements in performance. If I were to use a lesser known brand and run out and can only get Stans (or Orange Seal etc) at my local shop (or at the race support shop) I don’t want to worry about either cleaning the old stuff out of the tire or if the chemicals are compatible.

My biggest recommendation if your going to switch to tubeless is get a plug kit and use it.

+1 for Orange Seal regular. Both Orange and Stan’s are good for sealing little pinholes like from goat heads, etc, but Orange does a noticeably better job at larger holes and/or cuts/holes on the sidewall (pinches from rim strikes, for example). Nowadays there are also a few great options for tubeless plugs that can help fix fairly sizable punctures. There is plenty of n=1 evidence out there for using these on MTB/gravel tires, but they are also really good for helping the sealant deal with punctures on road tubeless at higher pressures. Recently I was riding with a buddy who got a fairly significant puncture from a piece of glass on his Schwalbe Pro One 28 tubeless tire. Sealant was spraying everywhere, and it was obvious it wouldn’t be able to seal. He jammed a single dyna plug in there and we were able to ride another 40 miles without incident. Since then, I keep a plug setup in my seat bag on my road bike, too.

Another vote for Stan’s. Caffelatte is also well rated but I have no first hand experience with it.

Stay away from Finish Line. They claim it lasts as long as the tires and isn’t affected using CO2 so no need to top up but it just goes slimy and doesn’t seal road TL very well.

Stan’s and Orange for me. Have had great success with both.

For days where I’m most concerned with a puncture, like races, then I do Stan’s Race Sealant.

I did some experimenting in the shop with Stan’s, Orange and Muc-off. We drilled holes and used a knife on the tire to synthesise a flat.
Stan’s filled holes, not slashes
Muc-Off sealed the biggest holes and slashes, but you needed A LOT of it to cover the inside of the tire.
Orange Seal sealed all holes like Muc-Off, and some slashes, but didn’t need as much.

I run Orange Sealant after this, (then I’d use Muc-Off, then I’d go for Stan’s)

Used Stans for years: MTB, gravel and road. No problems. One sidewall gash that needed plugs and tape but that was most definitely the sealant and not the utter idiot who jumped an XC bike with XC tires into a rockgarden… The gash was about an inch and it held, so I’m happy with Stans…

I’ve found standard Stans for MTB works great - been using it for years. But didn’t work for road tyres - had better luck with Orange and Stans Race sealant.

Obviously a lot of recommendations for Stans and Orange, but I can also recommend Muc-Off sealant, CO2 compatible, sealed up and holding pressure well in Hutchinson Fusion 5 Performance rubber. I did have a gash fail to seal (about 5mm long), but it’s absolutely fine now I’ve patched the tyre. The bottle it comes in allows direct pouring through the valve so less mess too.

One downside of the Mud-Off sealant is when it dries it can break down into tiny balls which work there way into the rim and can make a rattle.

Don’t get Finish line. The never dries out sounds good but it never hardens on a p’ture hole either. I found I was getting tiny p’tures which any other sealant would seal but FL wouldn’t I’d gradually lose pressure then if I hit something like a cat eye the whole tyre would unseat. I almost gave up on tubeless until I realised it was the sealant. I’ve used mainly Joe’s or Stan’s in the two years plus since without a problem.

I’ve always used what’s cheapest. Usually either Goldilocks or Trucker Co. Both have worked fine. Been tubeless for 6 years on 3 of 4 bikes. Not tubeless on the road as it is a pain in the ass and takes to long to clean up and fix on a group ride. Felt great though.
