"
For how long do manufacturers have to provide genuine spare parts?
The short answer is that there is currently no legislation that states that spare parts have to be available for any set period of time, either in UK or EU legislation.
What this means is that if you buy any equipment such as a compressor, dryer or pneumatic tool, the manufacturer or brand owner has no responsibility to ensure that spare parts are available for any set period at all, and you have no recourse in law to challenge a genuine spare part not being available."
