Dunlop
— an outdated type of nipple, once widely used in Soviet bicycles. It has a diameter of about 8 mm and thinning at the end; between the thick and thin part, there is a washer, when unscrewing it the valve opens and the air comes out of the wheel. Bicycles with a similar nipple are rarely produced, however, there are many old, but quite functional units, so Dunlop compatibility is still found in modern bike pumps.
