True Refrigeration 66237-4 Gasket 21-3/4 X 29-1/2

This gasket’s dimensions vary a bit from the one I’m trying to replace. How will I know if it fits?

The best way to ensure compatibility is to find the part number for your gasket, since the OEM and equivalent gaskets we sell will use the manufacturer’s specifications for that gasket. Dimensions are a good guide, but gaskets can be measured in a variety of ways – for example, if you measure your gasket from the centerlines (darts) vs. the maximum width and height those dimensions will be different for the same part number. The figures we display are generally provided by the manufacturer and information may not be available on which method was used to measure.
