Hintz scored on a wrist shot from the right face-off circle 15 seconds into the second period to increase the lead to 4-0.
The line of Robertson, Hintz and Pavelski combined for seven points (three goals, four assists) and nine shots.
"We've played the right way, we've gotten a little bit of puck luck along the way, some bounces, but we've worked to get multiple chances," Pavelski said of his line. "In this league, you find out you kind of need a couple good chances just to get one, and the guys are playing hard."
Bratt scored a power-play goal on a snap shot from the left face-off circle to pull the Devils within 4-1 at 12:16.
"They keep the puck along the wall, and a couple of lines are really quick," Devils coach Lindy Ruff said. "I think they know their strength is keeping the puck out of the danger areas ... every puck went deep."
