Oxford United extended their unbeaten run to five matches, their best since March 1997, but two solid defences ensured there were no goals at the Kassam Stadium.
Since the 2-2 draw with Torquay United on September 7, Oxford have achieved three straight wins on their travels but they find scoring more difficult at their new stadium.
Hull, languishing in the lower half of the division, had the clearer chances in an evenly contested first half and Oxford keeper Andy Woodman twice saved from Gary Alexander and kept out efforts from Ryan Williams and Phil Jevons.
Oxford's biggest threat on Hull's goal came after 14 minutes when a hurried clearance by a defender struck David Savage and the ball looped dangerously across the face of goal and inches past the far post.
Oxford raised their game in the second half and for long periods had Hull's defenders on the back foot but they were unable to create any clear-cut chances.
The best was wasted on the hour by full-back Scott McNiven who blasted a pull-back from David Oldfield over the bar from ten yards.
Bobby Ford was by far the best player in midfield and nine minutes from the end he started and finished a move that deserved a goal.
He linked up with Andy Scott and James Hunt in a short passing move which put him clear of the visitors defence but Paul Musselwhite pushed his shot away.
Hull's defence held out and when they hit back late in the game substitute Lawrie Dudfield twice had chances to snatch victory.
Four minutes from the end he won the ball off Woodman outside the area and drove wide of an open goal from a narrow angle and with the last kick of the match hit a spectacular shot narrowly wide.
The result satisfied both managers. "I've no complaints at the way we're trying to play but we need a bit of devilment near goal," said U's boss Ian Atkins.
"We were not brave enough to throw more players into their box."
Hull manager Jan Molby attributed the result to a lack of ambition. "There was a lot of respect out there from both teams," he said. "They were not prepared to gamble, nor were we."
