The Shannonsiders had a 1-11 haul from their lethal inside line as they set up a July 8 provincial decider against Cork.
Tipp have contested the last three Munster finals in this grade but were outclassed by their opponents as captain Willie Griffin led by example once again for Limerick.
Griffin bagged 2-6 in the quarter-final victory over Waterford and hit 0-5 yesterday.
Full-forward Tom Morrissey collected 1-3 and in the other corner, Mike Fitzgibbon helped himself to 0-3.
Limerick had nine different scorers on a day when Tipp were over-reliant on Adrian Ryan and Liam McGrath for attacking inspiration.
McGrath, Tipperary’s 2011 All-Ireland minor winning football captain, finished with a haul of 1-5, including a late consolation goal.
Ryan scored four points, split evenly between both halves, but Tipp didn’t help themselves with a haul of 13 wides.
And it was Limerick, despite playing against the breeze from the start, who roared into a 0-6 to 0-0 lead within 10 minutes.
McGrath finally opened Tipp’s account with a 10th minute free but Limerick led by 1-10 to 0-7 at half-time, as Morrissey pounced for a 30th minute goal after Griffin’s initial effort was saved.
Tipp were 11 points down on three occasions in the second half but did manage goals from Kieran Morris and McGrath to make the final scoreline more respectable.
Limerick had class running through every line of their starting 15, starting with the presence of 2007 All-Star Brian Murray between the sticks.
At centre-back, U21 star Diarmuid Byrnes stood out and the Patrickswell man banged over four trademark scores from long-range placed balls.
“We never got to the pace of it at all today,” Tipperary boss John Carroll admitted, while Limerick boss Don Flynn reflected: “Tipp beat us by a point last year and we wanted to turn them over today. We were well up for it.”
