Product details
Conavi emergency tyre repair foam – instant puncture sealant (450ml)
When you’re stuck at the side of the road, you want something that works and works quickly. The Conavi CX450 is one of those handy little canisters designed to get you moving again without the faff of a jack or spare wheel. It acts as both a sealant and an inflator for punctured tubeless tyres — ideal for when a nail or shard of glass ruins your tyre and you need a quick, temporary fix to get to safety or the nearest garage.
what it does
The foam plugs small to medium punctures from the inside while reinflating the tyre so you can drive a short distance at a modest speed. It’s a temporary repair to help you get off the hard shoulder or away from a busy junction and to a tyre specialist. It won’t replace a professional repair, but it saves time, hassle and the need to change a wheel on the side of the road.
key features and benefits
- Instant action: seals and inflates tyres in seconds for a quick, temporary repair.
- Multi-vehicle use: suitable for cars, motorbikes, scooters and many tubeless bicycles.
- TPMS and rim safe: formulated to be compatible with tyre pressure monitoring systems and alloy wheels.
- Portable: 450ml canister that slips easily into a glovebox, the boot or a pannier.
- Simple to use: attach to the valve, release the foam and drive slowly so the sealant spreads.
how to use
Take off the valve cap, fit the can’s adaptor onto the tyre valve and dispense the foam following the instructions on the can. If needed, top up to a safe pressure and then drive gently for a few minutes to help the product coat and seal the damaged area. Head straight to a garage afterwards for a proper inspection — this is only a temporary measure. It’s worth noting: this product is for tubeless tyres only and won’t work on inner tubes.
typical situations where it helps
- A nail in the tyre on the morning commute — saves time and stress.
- Late-night punctures when the garage is shut — handy when you need a speedy fix.
- Road trips — a compact backup that avoids changing a wheel on a remote stretch of road.
- Winter emergencies — when cold, wet conditions make swapping a wheel a right palaver.
Technical bits: model CX450, 450ml canister, roughly 380 g item weight and compact packaging that won’t hog much space. Even though the formula is designed to be TPMS- and rim-friendly, you should still have the tyre professionally checked and properly repaired or replaced as soon as possible. If you’re unsure whether a puncture is too big to seal, best to call for help rather than press on with a compromised tyre.
All told, the Conavi emergency tyre repair foam is a straightforward, no-nonsense roadside aid. It’s not a permanent cure, but it’s a practical, reliable short-term solution that gets you where you need to be without unnecessary bother.
