Each team played for the first time since the Flyers won 3-0 against the Penguins at Wells Fargo Center on Jan. 21.
"I liked our 5-on-5 game tonight," Philadelphia coach Alain Vigneault said. "Thought we got better, and our execution got better, as the game went on, both defensively and offensively. Against a pretty good hockey team, we've played five pretty good periods of hockey. Now we got a point tonight."
Crosby circled above the slot before shooting blocker side from atop the right face-off circle for his ninth goal.
Pittsburgh scored three straight goals to take a 3-1 lead before Pitlick and Scott Laughton scored for Philadelphia to tie it 3-3.
Pitlick went glove side with a snap shot, cutting it to 3-2 at 16:29 of the second, and Laughton scored on a wrist shot by finishing a pass from Kevin Hayes that went through traffic and off Pitlick at 2:20 of the third.
"Obviously, you want to get two points," Pitlick said. "It is what it is. I thought we had a good effort. We played really well in the third period. Most of the game, played a simple game. Didn't have a lot of turnovers or anything like that. So I thought we had a good effort."
After Jakub Voracek put Philadelphia ahead 1-0 on a power play with 29 seconds remaining in the first period, Malkin tied it 1-1 at 3:55 of the second by tapping in a rebound off a shot from Patric Hornqvist that Elliott failed to glove.
Bryan Rust gave the Penguins a 2-1 lead on a power play at 5:16 for his 22nd goal before Kris Letang made it 3-1 by banking a shot off the back of Elliott for a power-play goal at 11:03 of the second.
"We definitely didn't have our best [in the third period]," Rust said. "We gave them quality looks there, but give a lot of credit to [Jarry]. He made some really big saves for us. We were able to push it to overtime and win it there."
