Due to upcoming changes in EU import regulations from 1st July 2026, we have temporarily paused deliveries to EU countries.
We are working to restore this service as quickly as possible and thank you for your patience.
Designed to restore the rapid, reliable firing cycle of your pneumatic tool, this replacement spring serves as a critical return valve and tension spring within the internal firing mechanism, ensuring clean staple feeding and crisp trigger response with every shot in machines such as:
