Split nuts for Pentair?

Hello all,

First let me say this site has saved me hundreds of dollars in pool chemistry and repairs thanks to all the contributors.

Today's problem..... Pentair IC40 plastic nut has a hair line crack. Same thing happened last year and I cut pipe, installed new union and nut. Not enough room on the side that is broken this year to cut and install new. Purchased a split nut off Amazon and it does not fit (thread wise) on the pentair IC40. I read somewhere else pentair makes their sizes unique.

Are split nuts for pentair products available? If so, part # and site please. THANKS
