Petr Sykora added his second goal of the preseason, strengthening his chances of making the team. Sykora scored on a breakaway off a pass from Zach Parise that got by three Flyers at 4:12 of the second.
The Flyers took a 1-0 lead on Scott Hartnell's power-play goal with 3:31 left in the first. Philadelphia used with few regulars, but Ilya Bryzgalov played the entire game and made 18 saves.
Martin Brodeur backstopped New Jersey's regular lineup and stopped 25 shots.
New Jersey (3-3) will open the regular season at home against Philadelphia (4-2-1) next Saturday.
