Jared McCann had two assists, and Philipp Grubauer made 23 saves for the Kraken (24-44-6), who had lost two straight.
Jesper Bratt scored his 25th of the season for the Devils (26-42-7), who were 0-for-3 on the power play and have lost seven of nine (2-5-2). Nico Daws made 23 saves.
"It's probably the reason we lost the game, our power play wasn't good enough," New Jersey coach Lindy Ruff said. "When we did get our opportunities, we missed the net or our execution wasn't very good. And then they score on the power play. So if you want to look at one thing in the game, it's probably that we could have generated momentum, we could have generated some good energy, and we didn't."
Beniers put Seattle in front 3-2 at 16:57 of the second period, getting to a rebound and shooting into an open net on the power play.
"We won the draw back and I was just crashing the net and it popped out to me," Beniers said. "Kind of a lucky goal for me, you don't get many like that. It was a great feeling and I just kind of jumped into [McCann's] arms. … After the goal it was electric, I couldn't help smiling."
Damon Severson tied the game 3-3 at 4:55 of the third when he shot past a falling Grubauer, who had tripped over the skate of Haydn Fleury.
"It's almost like we're missing a bit of that swagger that we had," Severson said. "I'll use that word. … Obviously, we're just going to try to simplify. When I say that, I mean like just getting more shots."
