Ovechkin deflected a shot by Dmitry Orlov to give Washington a 3-1 lead at 8:55 of the second period.
"It's nice to be in that company," Ovechkin said. "It's pretty big numbers so just move on. Obviously, it's nice to be tied, but I still have a couple games left."
Ovechkin has played 1,209 regular-season games during 17 seasons with Washington, which selected him with the No. 1 pick in the 2004 NHL Draft. Hull played 1,269 regular-season games in 19 NHL seasons with the Calgary Flames, St. Louis Blues, Dallas Stars, Detroit Red Wings and Coyotes before retiring in 2005.
"It's fun to watch," Hull said of Ovechkin. "I wouldn't say he's one of a kind until he possibly passes Wayne [Gretzky]. Then he can be one of a kind. But he is part of a group of guys that could score. Just to keep doing it like he is, you have to tip your hat to him. He's a great player."
Ovechkin leads the NHL with 11 goals in 12 games this season. He passed Marcel Dionne for fifth in NHL goals by scoring No. 731 and No. 732 in a 5-1 season-opening win against the New York Rangers on Oct. 13.
Ovechkin needs to score 37 goals this season to pass Jaromir Jagr (766) for third in NHL history, behind Gordie Howe (801) and Gretzky, who is first with 894.
"Well, let's don't jump ahead," Ovechkin said when asked about catching Jagr. "We have to get [past Hull] first and then we are going to talk about it."
Gretzky said again before this season that he believes Ovechkin can break his record.
"First of all, he's definitely got a legitimate shot," said Gretzky, a studio analyst for the "NHL on TNT." "... He's got a great opportunity. He's on a good team. He plays with really good centermen. He enjoys playing and loves playing in Washington. So he just has to be himself, go out there and play hard like he does every night."
Ovechkin nearly scored 2:13 into the game with a redirection of a Trevor van Riemsdyk shot, but the puck deflected off Tom Wilson's elbow before getting past goalie Dustin Tokarski.
"If it wasn't for me, he would have passed Hull," said Wilson, who scored two goals. "He tipped it off my arm or something. I should have just got out of the way and we would have been talking about Jagr."
Ovechkin had two assists against Buffalo, getting him to 600 in the NHL.
"He's moving the puck well," Washington coach Peter Laviolette said. "The line (with Wilson and Evgeny Kuznetsov) is moving the puck well, and inside of that, there's going to be times where we need people in front of the net. He does go there, and that goal was a good example. There was somebody in front, he was the second layer, and he was able to get a piece of it."
