Use this catalogue to identify the spare parts you need to repair your compressor. The OEM catalogue is crossreferenced with our spare parts database, matched items are highlighted. Some of our existing spare parts may not be shown because our database is incomplete (e.g. missing OEM P/N), or because we sell the items separatelly (typical example is the piston-connecting rod assembly). If you have any doubt please ask us.
All OEM manufacturer's names, part numbers, diagrams, products description and information are provided for reference and identification purposes only, and it is not implied that any part listed is the product of the OEM manufacturer.
