This button features a gray background with bold black "N" (Nitrogen) lettering, adhering to the SEFA (Scientific Equipment and Furniture Association) color-coding standards.

Expert Insight:
The 216-578JKNF is the industry-standard marker for Nitrogen service, where the gray color provides an immediate visual distinction from oxygen or air lines. Installation Tip: These buttons use a "friction-lock" tab system. When installing, align the "N" so it is upright relative to the user before pressing it into the handle; once snapped in, they can be difficult to rotate without prying them back out. Pro Tip: Nitrogen is often used as an inert "blanket" or for sensitive drying processes; using a correctly labeled "N" index is vital to prevent someone from accidentally connecting a different gas that could cause an adverse reaction. These buttons are made from a high-density polymer that resists the brittleness often caused by dry gas environments.
