Torquay extended their unbeaten League Two run to four matches following a goalless home draw with promotion-chasing Dagenham.
Genuine goalscoring opportunities were at a premium with United defender Mark Ellis sending a 19th-minute volley wide from the far post following skipper Nicky Wroe's corner from the right.
A minute later visiting keeper Tony Roberts made a routine stop from Chris Zebroski's 18-yard shot on the turn.
Daggers striker Josh Scott glanced a header just wide from Jon Nurse's angled cross from the left in the 28th minute as the visitors finally countered with intent.
Wroe's 58th-minute shot from the edge of the area flew just wide as the home side went in search of the opening goal.
Lee Mansell came closest to breaking the deadlock, thumping a dipping 25-yard shot over Roberts and off the bar.
Roberts made a superb stoppage time diving save to keep out Eunan O'Kane's goalbound free-kick from the left.
