got a seal kit that calls out part number C1DQ57, that the same thing as this poly-pak here?

Answer by: Customer Support on Jul 21, 2025, 8:13 AM

Yeah, C1DQ57 is one of the alternate part numbers tied to this exact product. MI-01197976 and MINO-00407X60336 also cross to it. If your kit paperwork shows any of those numbers, you're looking at the right seal.
