New Primpact module assembly

A redesigned Primpact module has been introduced in 2015 on all P250A & P250F tools. The significant change consists of the assembling of the head and the cylinder. In the new version, the two components are now snapped together as compared to the previous version which were screwed together.

There are now several components that are no longer compatible between versions, including main body, head, head cap, cylinder, valve and bumper.

Check which version your tool is when ordering replacement parts.
