A vibration isolator suitable for isolating and/or dampening vibrations generated in a vibrating machinery component such as a motor or pump so as to minimise the unwanted effects (such as audible secondary sounds) of those vibrations. The isolator may be installed in a home appliance such as a laundry washing machine and may be a separate, unitary component installed between a motor/pump and the structure of the laundry machine or may be installed between a mounting bracket of the motor/pump and the laundry machine. Alternatively, the isolator may be integrally formed with a pump/motor mounting bracket, on upper and/or lower surfaces of a mounting flange. The isolator is preferably formed from a substantially incompressible material and in one preferred embodiment has a washer-like form with a central opening at least partially surrounded by a tubular ridge with a plurality of radial projections extending outwardly and/or inwardly from outer/inner surface(s) of the tubular ridge.
