Integrated diamond & nozzle nut (IDNN). For fastest maintenance in small spaces, with limited time. Diamond and nut are 1-piece. Apply a small amount of blue anti-sieze to face or use the brass seal to prevent galling. The IDNN will last longer than other diamond mounts, even with multiple cleanings.
