A vibration isolation mount 5 for a compressor, the mount being formed of an elastomeric material and comprising a sleeve 60, a plurality tapered studs or axial ribs 62 spaced around the sleeve, and a lip seal 61 extending around the sleeve. The mount is intended to be located between a compressor and a housing. The studs or ribs then deform to isolate the housing from radial vibration of the compressor, and the lip seal creates an annular seal between the housing and the compressor. Preferably the lip seal is more compliant radially than the studs or ribs.
