Viton (FKM) seal kit for the M4MF-21 hydraulic motor.
Viton (FKM) seal kit for the M4MF-21 hydraulic piston motor, from the Bondioli & Pavesi M4 family, which works with M4PV pumps on hydrostatic transmissions.
Viton withstands higher oil temperatures and special fluids that attack NBR. The kit is used to reseal the motor after opening it, because of leaks at the shaft or at the covers.
Before ordering, check on the nameplate that the motor is an M4MF-21 and whether the original sealing is Viton.
