I have the a fitting with 1.5 inch barb (from Lowes) and 1.5 inch Trident 102 and WOW - I can't couple them together.
That's because, unlike marine fittings, the 1/5" barb you bought at Lowes has a 1.5" INNER diameter...its outer diameter is 1 5/8". Don't even think of using heat and lubricant...get thee to a marine store and get the right kind of fitting.
In the '80s and early '90s boat stores--and my company--were selling 1.5" gray pvc thread-barb tank fittings that were the scourge of everyone who tried to get a hose onto one of 'em. The THREADED end was 1.5" OD, but the barb end was 1.5" ID...1 5/8" OD same as you got. I prob'ly got 3 calls a week, complaining about 'em. Took me close to a year to figure out what the problem was.
