Pirelli’s bright new yellow tubeless sealant pours road, gravel & MTB versions

The new Pirelli tubeless tire sealant comes in two unique formulas, one for high-pressure road use, and the other for gravel, mountain bikes, and urban/commuter bikes.

Both are bright yellow, which should make spotting smaller punctures easier, and they’ll come in a huge range of bottle sizes, from single-use to shop jugs…

For road bikes, the Pirelli P-Zero sealant uses an ammonia- and latex-based formula made for higher tire pressures and is CO2 compatible. It also has micro-sealing particles to help it plug the hole quickly, and it’s good from -20ºC (-4ºF) up to 70ºC (158ºF).

For gravel and MTB, there’s the Cinturato / Scorpion blend, which is the same, but named differently depending on the bottle simply to match their tire nomemclature to reassure you at retail that you’re getting the right thing.

This formula is ammonia- and latex/protein-free, so it’s safer for all rims and is hypo-allergenic. They say it works well with tire pressures from 1bar (15psi) to 7bar (100psi) across the same temperature range as the P-Zero road sealant.

They say this low-pressure version is only CO2 compatible in an emergency, that the gas will speed up coagulation, so you’ll want to replace the sealant when you get done with the ride. Otherwise, both versions are good for 3-6 months depending on weather conditions and quantity used.

At launch, the P-Zero High Pressure Sealant only comes in a 60ml (2oz) single-use bottle. The Cinturato / Scorpion version comes in a 125ml (4.5oz) travel bottle, and larger 240ml (8oz), 1L (33.8oz) and 5L (175oz) bottles for home and shop use.

Pirelli says all of them run clean and won’t leave a sticky residue inside your tire when it’s time to refresh it.

Who in the world puts sealant in that way? You inject it through the valve stem for crying out loud.

I was as ignorant as you until I experiences Silca sealant which poured in the same way

Loads of people do! Stops the valve stem from clogging up.

I put sealant inside of a tire both ways. For tires with easier beads I’ve poured it in then went around the edge of the Pizza. Makes it pretty easy as I just grab the inflator, pop it onto the valve press the button and the tire is both seated and inflated without having to clean an additional tool afterwards or remove a valve core. For tougher beads I use the injector but re-screw on the valve core prior to inflation/seating.

The label on the bottle shows it is ammonia free, latex free, and NOT CO2 compatible. You can’t use ammonia based sealants with AirLiner inserts.
