Marc Newsham had his penalty saved by keeper Tim Deasy in the fifth minute of added time after Nathan Hotte and Matty James had sandwiched a Mark Jones leveller.
Newsham and Gary Silk both hit the post for United, while both keepers were kept busy, but Deasy was hailed as the hero after becoming the first custodian to stop Newsham scoring from the spot during his four seasons with the Pilgrims.
