Need to fix a leaky oven door on your Southbend commercial-style range? This is the genuine replacement door gasket you're looking for. The part number is 1185135, and it's designed specifically for the Southbend R2 Deluxe 5-PAN series ovens. Over time, the original gasket (that black rubbery seal around the door) can get brittle, cracked, or compressed, which lets heat escape and makes your oven less efficient. Replacing it is a common repair that can really help your oven retain heat properly again. This is the official part, so you know it will fit and perform correctly. Before ordering, always double-check your oven's model number to make sure this gasket is the right one. Installation usually involves removing the old gasket from the channel in the door and pressing this new one into place. It's a relatively straightforward fix that can make a big difference in your oven's performance.
