In a residential chilled water distribution system using 1" pex with F1960 expansion fittings, are there any simple/easy products available for insulating the tee fittings?

I assume that the typical preformed insulation tees for use on copper wouldn't fit very well, because the OD of the installed pex rings is much greater than the OD of a copper fitting solder cup. If I'm mistaken and there is a way to use those, that would be great.

The pipe runs are to be insulated with 3/8" thick Armaflex LapSeal. The ideal product would be pre-molded on the inside to conform to the profile of the assembled tee and pex rings, and should have legs on the pex runs that taper down to 3/8" insulation thickness. It should be vaportight, since the point of insulating is to prevent condensation.

Thanks,
Wayne
