Pulis started with former England team-mates Michael Owen and Peter Crouch in attack, but it was Championship side Palace who looked most likely to break the deadlock.
Wilfried Zaha was particularly impressive, although Yannick Bolasie, Andre Moritz and Jason Banton all also went close for the home side.
Pulis said: "When the draw was made we knew this would be a very tough fixture, especially away from home.
"We have just come off the back of four very tough Premier League games. This is a tough ground to come to and they are a top Championship side.
"They played really well. They have got some dangerous players in their team and we are pleased with the result.
"They are a good side. Ian Holloway's got them well-motivated and it was always going to be difficult."
Pulis said he had no intention of resting players and used all the resources at his disposal in an attempt to snatch a win.
He added: "I was bringing on players like Kenwyne Jones, Cameron Jerome and Charlie Adam to try to win the game.
"But both teams are in the draw, so that's something to look forward to."
