4an Bottle Nipple & Nut For CO2 Valve

The 4AN Bottle Nipple & Nut For CO2 Valve is a precision adapter designed for operators and technicians who demand reliable connections in high-pressure pneumatic systems. This fitting bridges CO2 valve assemblies to 4 AN male connections, making it essential for nitrous oxide injection systems, pneumatic tools, and specialized equipment common in performance and tactical applications. Built by NITROUS EXPRESS, a manufacturer with proven expertise in pressurized delivery systems, this nipple and nut assembly ensures leak-free performance in mission-critical scenarios where system integrity cannot be compromised.

Constructed from black anodized aluminum, the 4AN Bottle Nipple & Nut delivers corrosion resistance and durability in demanding environments while maintaining a lightweight profile—critical when every ounce matters in field operations. The straight adapter configuration minimizes pressure drop and turbulence, maintaining system efficiency while the included gasket ensures a hermetic seal that prevents loss of pressurized gas. The 4 AN male connection standard aligns with mil-spec and industrial pneumatic standards, allowing seamless integration with compatible manifolds, regulators, and distribution lines. Anodized aluminum finish provides protection against oxidation and UV degradation, extending service life in both indoor and outdoor tactical deployments.

This adapter serves personnel managing CO2-based systems across law enforcement, military support, and specialized equipment operations. Installation is straightforward—thread the nipple into the CO2 valve outlet, secure with the nut, and connect the 4 AN male end to your downstream assembly. The compact 1.9 x 1.5 x 4.85 inch footprint minimizes spatial constraints in tight equipment configurations. Verify thread compatibility with your specific CO2 valve before purchase, as nipple thread sizes vary across manufacturers. Regular inspection of the gasket ensures continued seal integrity, particularly in high-cycle applications or after extended storage periods.
