I'm running several hundred feet of IPS DR11 2" HDPE from my water holding tanks to various risers in my orchard. The supplier had the HDPE in stock, but not the fittings. So, I ordered the fittings separately. But, now I'm concerned that I didn't get the right size fittings.
The DR11 2" HDPE has an average interior dimension of 1.917", according to what I think is the catalog for it:

However the fittings I have are:
Dixon RDM26 insert x insert pipe mender; exterior dimension exactly 2", according to
https://dixonvalve.com/en/products/dixon-hose-mender/rdm26
Dixon RST25 insert x male king nipple; exterior dimension 2 1/32", according to
https://dixonvalve.com/en/products/king-combination-nipple-npt-threaded/rst25
I haven't worked with HDPE before. When I heat it with a propane torch, how much can I expect it to stretch/expand? If these fittings are too large, what is the right way to shop for the correct sized fittings?
