NFPA-spec tie-rod cylinders built to U.S. industrial standards, with imperial bore and stroke dimensions for retrofit and new-build applications. This subcategory carries the Numatics-heritage lineup — TaskMaster, PowerMaster, and related series — that has anchored Aventics's North American business since the 2010 Numatics acquisition. The right choice when a project spec calls out NFPA dimensions or when matching existing installed equipment.
