Customer questions about this product

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.

This Avantco 178GSKT17757 lid gasket is a perfect replacement for the one that came with select HBB and GF series units. It is a vital part of your unit's lid assembly, working to create a firm seal and keep the cabinet set to the right temperature. A broken or malfunctioning lid gasket can prevent your unit from maintaining specifications and cause strain on other components, so be sure to replace it promptly.
