The Impac DV12 is a 12-inch inner tube for tyres in the ETRTO 47/62-203 range. It is fitted with a 26 mm Dunlop valve, a common valve style on city, child and utility bikes in many European markets.
Before fitting, compare both the ETRTO 47/62-203 range and the valve type with the old tube and rim. The tube must sit inside a compatible 203 mm bead-seat-diameter tyre and the rim must accept a Dunlop valve.
