The teams produced nine goals the last time they met but although there were no goals on this occasion the match was not short on incident.
County's Sam Morrow headed against the crossbar in the first half and the visitors twice thought they had broken through in the second, with Sam Parkin denied by a post and John McGinn's effort cleared off the line.
After kick-off was delayed by five minutes as the lights temporarily went out, the home side made a bright start as an Iain Vigurs shot was blocked in front of goal in the fifth minute after he played a one-two with Rocco Quinn.
Kenny McLean let fly from distance at the other end but his effort was well wide of Mark Brown's left-hand post.
Play was swinging from end to end and McGinn picked up a loose clearance from Ross Tokely, but inside but this time his effort was straight at Brown.
County came closest to an opener in the 16th minute when Brittain sent an inviting cross into the box for Morrow, whose header crashed off the face of the crossbar before being cleared.
Saints came close themselves five minutes later when Jim Goodwin drive just cleared Brown's crossbar after some stout defending from the home side.
The chances kept coming and after McLean lashed a shot wide whilst in a good position, Vigurs whipped a free-kick just wide of Craig Samson's left-hand post.
The County man looked as if he was heading clean through when he was taken down by Lee Mair, who became the first player to go into referee Steven McLean's book
The visitors were pressing for the opener and they came close again in the 59th minute when the ball fell for McLean, but his shot from 12 yards broke off Tokely and behind for another corner.
Samson was forced to make his first save of the match in the 70th minute when Vigurs got on the end of a Mark Fotheringham pass and his shot was on target before the Saints keeper got a hand to it at the near post.
But it was mostly Saints and Scott Boyd, making his 200th appearance for County, was forced to clear the ball off the goal-line in the 77th minute after McGinn made contact with a Parkin knock down.
