Replacement pads, extension hoses, AC adapters and insulation barriers are available for all current models (Polar Care Cube, Glacier, Kodiak and vPulse) of Breg cold therapy units.
Gasket seals, water filters, hose connectors and other repair parts are not available. Cold therapy units are FDA regulated medical devices and as such are intended for use in a single medical care instance (one knee or shoulder repair/replacement, etc.) After that, the manufacturer recommends the unit not be saved for future use, given or loaned to someone else, etc.
Breg Polar Care 300 and 500 models are very old and should be disposed of and not used.
