Choosing the right tubeless sealant
Most riders don't need the "best" sealant so much as the right one for how and where they ride.
A quick guide:
Mountain bike (trail, enduro, gravel)
You want a sealant that plugs bigger cuts and copes with lower pressures. Stan's NoTubes is a proven all-rounder here, and Joe's No Flats is a solid value option for everyday trail use.
Road & fast gravel
Smaller volumes, higher pressures and smaller punctures, so you want a fine, fast-sealing formula.
Silca Ultimate is a fibre-reinforced sealant popular with road and gravel riders; Stan's and Muc-Off's Road & Gravel formula also suit high-pressure road setups.
Everyday & commuting
Longevity matters more than outright seal speed. A long-life sealant means fewer refresh sessions between rides.
Not sure what suits your tyres? Ask our workshop team — we set up tubeless wheels every day and can match a sealant to your bike, tyre width and riding.
How our sealants compare
The sealants we stock each do a different job.
Here's how they compare, drawing on independent testing (CyclingWeekly, BikeRadar) and each brand's own specs:
Silca Ultimate
Best for big holes and high pressure.
Its FiberFoam formula suspends recycled carbon-fibre strands that build a dam across a puncture, sealing holes up to 7.5mm — the largest in independent group tests — and holding firm at road pressures.
It's CO2-safe. The trade-off is a premium price, and some versions need to be poured in rather than injected.
Stan's Race Tubeless Sealant
Best for racing and fast MTB sealing.
It uses around twice the particulate of standard Stan's, so it clots quickly and plugs roughly 6mm holes with minimal air loss at trail pressure.
The trade-off:
It dries out faster than the others, tends to form rubbery clumps ("boogers") over time, and can gum up if you inflate with a CO2 cartridge.
Muc-Off No Puncture (Road & Gravel)
Best for higher-pressure road and gravel.
A zero-ammonia synthetic-latex formula with biodegradable bamboo flakes and natural-fibre particles that plug holes up to 7mm and hold at pressures up to 110psi. CO2-safe, and lasts 3–6 months.
Muc-Off No Puncture (MTB)
Best for trail, enduro and downhill.
Tuned for 15–80psi, it seals tears up to 6mm, plugs porous casings and bead gaps, and adds a UV dye to spot leaks. CO2-safe, lasts 6+ months and won't ball up.
How much tubeless sealant do I need?
Sealant is dosed by tyre size, so bigger tyres need more.
Use the ranges below as a starting point and always check the dosage chart on your chosen sealant, as amounts vary by brand:
- Road & gravel (28–45mm): 30–60ml per tyre
- Mountain bike – Trail (2.20–2.40"): 60–100ml per tyre
- Mountain bike – Enduro & Plus (2.50–2.80"): 100–150ml per tyre
- Fat bike (3.80"+): 150–240ml per tyre
A tubeless sealant injector or syringe makes this easy and mess-free — you can add sealant straight through the valve without breaking the tyre bead.
Topping up and refreshing your sealant
Sealant doesn't last forever.
It slowly dries out as it seals small punctures and loses moisture through the tyre casing, and in Australia's heat that happens faster than the packaging often suggests.
Check yours every couple of months and refresh it at least every 6–8 months.
Left too long, old sealant turns into a rubbery skin or clumps ("boogers") inside the tyre and stops sealing punctures.
For a quick top-up, add fresh sealant through the valve with a removed valve core and an injector.
For a full refresh, remove the tyre, drain and wipe out the old sealant, and clean off any dried residue with Muc-Off Glue & Sealant Remover before you re-mount and add fresh sealant.
Running inner tubes? There's a sealant for that too
Tubeless sealant is designed for tubeless tyres, but if you run inner tubes you can still get puncture protection.
Muc-Off Inner Tube Sealant goes inside the tube, lasts the life of the tube and doesn't dry out, and seals punctures up to 4mm.
Your tube needs a removable valve core so the sealant can be injected.
Complete your tubeless setup
Sealant is one part of a reliable tubeless system. It works alongside your tubeless bike tyres, tubeless valves and rim tape, or grab a tubeless conversion kit or tyre inserts if you're building or protecting a new setup.
