19x32x7 22.7x47x7x7.5 27x37x7 mm includes O-ringsAs a rule of thumb, to ensure correct positioning of your fresh oil seals, the 'open' side of the seal always faces towards the one of the chambers that it separates, with the higher pressure. This higher pressure also helps the inner circumference maintain the seal to the shaft by pushing the inner edge against it.
