The thread sealing nut and copper washer are then screwed onto the repair insert, securing it in place and creating a tight seal.

This NAPA Spark Plug Thread Repair Kit is ideal for use in various applications, including personal vehicles, commercial fleets, and industrial equipment. By repairing damaged threads instead of replacing the entire engine component, this kit can save time and money while ensuring optimal engine performance.
