AC expansion tube install
 

Hi guys,
I'm converting my R12 to R134 for the upcoming season. I've changed all the fittings and out of an abundance of caution I decided to check the expansion(orifice) tube. I took a little of a tug to remove it and as it turned out it was fine. When reinstalling it I kind of buggered up the end so now I'm waiting on a new one. My question is, is there a tool or a trick to reinstalling this expansion tube? Thanks
