Brad Richards scored his 15th goal of the season for New York and Derek Stepan took advantage a gaffe by Penguins goalie Marc-Andre Fleury to notch his ninth goal as the Rangers won their fourth straight.
New York improved its position atop the Eastern Conference by riding Lundqvist, who has won six straight starts. He held the Penguins in check with a series of flashy glove saves and dug in when Pittsburgh turned the pressure up late.
Ben Lovejoy scored his first goal of the season for Pittsburgh and Fleury stopped 18 shots but badly misplayed a clearing attempt in the third period, leading to Stepan's goal.
The victory capped an eventful week for New York, which has surged to the top of the Eastern Conference standings over the past month despite the presence of camera crews that documented the build-up to the annual Winter Classic in Philadelphia on Monday.
