Mafioso-turned-canary Salvatore Gravano, in a wide-ranging new videotaped interview, even weighs in on some of the conspiracy theories surrounding pedophile Jeffrey Epstein’s death.

“I was in 9 South,’’ Gravano, aka “Sammy the Bull,” said in the YouTube chat, referring to the wing at the Metropolitan Correctional Center in Manhattan where he spent time holed up years before Epstein.

“It don’t take long to kill yourself, if he hung himself. I don’t believe anybody killed him. I think he knew it was over … and he took himself out,’’ the former Gambino crime family mobster said of the 66-year-old accused sex trafficker’s death in August.

Gravano — speaking on video for the first time in more than two decades — added that he was disgusted that the rich and famous, including former President Bill Clinton, chose to pal around with Epstein at various points.

“We also know he’s a f–king degenerate,’’ Gravano said of Clinton before adding, “Don’t take that personal, Clinton, wherever you are, that I’m calling you a degenerate.

“But you are what you are. I’m a man. I understand. But when you hit a certain point, you gotta keep your zipper closed. You can’t be nailing a 21-year-old. She’s old enough to know better, and I give you that. But still, you’re in a tremendous position of power. But you’re a douche, I don’t even want to talk about you,’’ he said, apparently referring to the married then-president’s Oval Office affair with White House intern Monica Lewinsky.

A rep for Clinton did not return a request for comment Monday.

Gravano is infamous for squealing on his Mafia boss, John Gotti, in 1992, helping to finally put the Dapper Don behind bars. The Bull was the highest-ranking mob turncoat at the time. Gotti died while still behind bars in 2002.

It is unclear where Gravano is currently living since being sprung from prison in 2017 after a nearly 18-year sentence for drug-peddling.
