The UnitedBuilt S32690MS mechanical seal is a 1-1/8-inch Type C replacement sealing component for the M3ZRMS water pumps listed below. It serves the mechanical-seal configuration, rather than the rope-packing arrangement used in M3ZRM pumps.
S32690MS is the mechanical seal component, not the complete M3ZRMS reseal kit. A broader reseal job may also involve the inner grease cap, water slinger and volute gasket. Checking those separate components before ordering helps you choose the repair scope without confusing a seal with an assembled powerhead.
