Continental Revo Sealant – Technical details
Revo Sealant is the only sealant produced by Continental and, while it is suitable for use in a tubeless tyre, and also within tubular or inner tubes, the information provided only gives details for use in larger tyres. Revo sealant is suitable for temperatures ranging from -20 degrees Celcius all the way up to 70 degrees Celcius.
Limited information is available but it is an ammonia-free and protein-free solution. The amounts required are similar to other brands, starting with 80-100ml for 2.0 to 2.1in and up to 120-150ml for 2.4 to 2.5in.
For our assessments using a 47mm (1.85in) tyre, the lowest recommended amount of 80ml was used.
Continental Revo Sealant – Performance
To test sealant performance, we created a standardised puncture test to assess each contender. The same exact tyre on the same rim for each sealant. The tyre used was a Halo GXC, measuring 47mm. Tyre sealant was added in the amount suggested by the manufacturer, and the tyre was inflated to 40psi. This pressure was chosen to give a realistic tyre pressure for all areas of off-road riding. A digital tyre pressure gauge was used to ensure that the pressure was identical on each test. After that, the tyre was rotated sufficiently to ensure that it was distributed evenly throughout the tyre. The tyres were all punctured by driving a 3mm nail through the carcass. The wheel was rotated to assess if the sealant had successfully sealed the hole. If the sealant worked, the test was repeated using a 5mm diameter nail and, if successful on the larger hole, the remaining air pressure was measured with a digital pressure gauge and the result was recorded.
Continental Revo performed well, sealing the smaller 3mm hole instantly. On a larger 5mm puncture, tyre pressure was measured at 35psi. We repeated the test on the rear tyre, which sealed with 37psi remaining.
It also lasted well, not showing any sign of drying out after several months. The small particles within the solution could also be seen clearly within the liquid with no clumping or sticking to the carcass.
Continental Revo Sealant – Verdict
Prices for Revo Sealant start at £6 for the small 60ml bottle to £13.45 for the 240ml, while the 1-litre comes sin at £39.95, which places it on the pricier side of the spectrum. For context, other sealants rated at 1-litre including top-rated Peaty’s Holeshot is £30, while Vittoria Universal Tire Sealant comes in at the same price.
Despite very little information being available through Continental, the sealant has performed well, with quick puncture sealing and no signs of drying out after several months of use. It’s not as well priced as some of its rivals, which may limit the appeal, but it stacks up well in terms of performance.
