This part closes out small openings, especially on JOST assemblies, to keep components clean and avoid contamination. It’s often added to jack systems or head assemblies and is a match for those needing a snug, threaded end-cap solution. When in doubt, the JOST NT0000005 saves time and keeps exposed threads protected without overcomplicating the job.
