Gravel TPU tubes built where TPU usually fails
It isn't trying to be the lightest, but the one that won't leave you stranded. Premium 0.35 mm TPU, double heat reinforcement at the valve base and an end-to-end joint with compression control.
Black Seal Gravel TPU Inner Tube 700c 32-42C Ultralight 64g
The IMPALAPRO Black Seal Gravel is a 700c TPU tube of 64 g in premium 0.35 mm TPU, with a 65 mm, 100 % metal Presta valve, a removable core and a double-reinforced base. Designed against the usual TPU failures: valve leaks, seam blow-outs and pressure loss.

Frequently asked questions
700C (28") wheels with 32, 35, 38, 40 and 42 mm tires (700x32C to 700x42C), so it also works as a 700x32 TPU tube. The maximum stretch is 0.3 %.
Yes. It's compatible with disc and rim brakes, and it can be fitted on rims with tubeless sealant residue.
64 g. It saves over 100 g against a butyl tube (150–200 g), and its 0.35 mm wall resists punctures far better than 0.20–0.25 mm TPU tubes.
Yes. It's a 65 mm, 100 % metal Presta with a removable core compatible with valve extenders.
Pre-inflate the tube to 20–30 % (max. 6 PSI) so it takes shape, insert the valve into the rim, place the tube evenly inside the tire and finish inflating to the recommended pressure. Don't inflate it outside the tire or use metal tire levers.
Its 0.35 mm wall resists punctures far better than 0.20–0.25 mm TPU tubes, and the double-reinforced valve base protects the joint where TPU usually fails. At 64 g it's still over 100 g lighter than butyl (150–200 g).
