Injectable through your valve, seals a 6mm+ puncture, and lasts up to 6 months. The perfect sealant for those looking for the ultimate sealing power, longevity, and ease of use.

The original sealant formulation, released 2.5 years ago, was designed primarily for effective puncture sealing by maximizing the surface area of the liquid latex for enhanced performance. Pro racers valued its convenience, as they frequently changed tires based on race conditions and could easily pour in fresh sealant without needing to inject it through the valve. However, we heard two main concerns from more casual cyclists—it dried out quickly when not in use, and its composition of the longer strand carbon fiber made injection difficult and problematic, leading to a potentially messy installation if not handled carefully. 

Please Note: Injectors are sold separately.

Lastly, the old Natural Latex formula needed a two-step process to stay liquid longer. That has been eliminated with our new blend of natural and synthetic latex. SILCA Ultimate Sealant Is a one-step process lasting +6 months and still, above all else, sealing punctures on race day.

Not for super chewers
Color: Blue
This ball seems to be of good quality; has held a charge well and is easy to use. Sadly, the cover lasted less than 15 minutes with our dog.... not for aggressive chewers for sure. Pretty funny to watch the hound dog jowls shake though.

Great fun for dogs!
Color: Orange
Two of our dogs really love this! It caused a lot of barking and chasing and running around trying to grab it. It's really funny to use the remote to control it (and especially make it stop when things get a little too chaotic!) It feels durable even when pawed and bumped into and stepped on. The battery life seems good. I plugged it in overnight to charge so not sure how long it took to charge, but it has lasted quite a while with the dogs playing with it and still doesn't need a charge. It's easy to screw off one side of the ball to plug it in to charge. The size is a little bigger than a tennis ball I would say and has a soft texture.

It doesn't work.
Color: Blue
The two halves of the ball shell come apart again and again when the dog plays with them. When it is time to recharge the core, it will not take a charge. The dog loves it, but it's unsafe to play with.

My dogs fight over it
Color: Orange, Color: Orange
Easy to use, durable, and has a great battery love. At first my dogs were curious and unsure about it, now its become one of their favorite toys. They'll stare at it while its being charged and impatiently wait for it so they can have fun again. Perfect size for most breeds.
