This Boiler Wrap Metal replacement with insulation is Metal the Brand-new Amish built cooling unit use which is a heavy gauge metal, not the thin aluminum foil Norcold OEM coils used on the older units.

This metal upgrade Boiler Wrap kit can be used to replace your OEM boiler pack with a little adjustment since the OEM coils would a little different design.  In some cases you may need to trim to fit. This is a minor issue.

Most of the time if you ever had to replace the  AC electric heating elements,  the old boiler pack will be damaged to a point it the boiler wrap must be placed. Most of the time the RV tech will just tape it back together. Norcold does have a metal boiler pack for the old 1200 series.
