Abstract
A liquid dispensing nozzle has an annular member of a relatively soft material at one end of a bellows, which is disposed in spaced relation to the spout of the nozzle to form an annular vapor return passage therebetween, to engage the fill pipe to form a seal therewith when the spout is disposed therein so that the vapors flow from the tank to the annular vapor return pasage of the nozzle. The soft seal member is removably fastened to the end of the bellows for easy replacement. The spout has a pair of latch rings thereon spaced from each other with each having a retaining lug to enable the spout to be retained within any type of fill pipe since one of the lugs on one of the latch rings is always capable of being retained by the lip of the fill pipe opening.
