part number MUU-20X28X5, is that the same seal that some folks list as C1MC35? trying to make sure i'm ordering the right one before i pull the trigger

Same seal, different number. MUU-20X28X5 is the Hercules part number, and C1MC35 is just an alternate cross-reference for the same product. Either number points you to this exact symmetrical U-seal, so if your old part or supplier paperwork shows C1MC35, you're looking at the right replacement.

Part number cross references are straightforward here. MUU-20X28X5 is the Hercules Sealing Products U-seal, and C1MC35 is listed as an alternate part number for the same item.
