#6 Male to #4 Male Port Ano-Tuff Adapter

The #6 Male to #4 Male Port Ano-Tuff Adapter is a precision hydraulic and pneumatic fitting designed for high-pressure fluid transfer systems in tactical, military, and industrial applications. Built to military and law enforcement specifications, this adapter bridges two different port sizes while maintaining system integrity under extreme conditions. Whether you're assembling a custom weapon system, maintaining tactical equipment, or working with pressurized fluid lines in field operations, this fitting ensures reliable connections where redundancy and durability are non-negotiable.

Manufactured by EARLS, a trusted name in performance fittings, the #6 to #4 adapter features Ano-Tuff coating—an advanced anodized finish that resists corrosion, oxidation, and chemical degradation in harsh environments. The male-to-male configuration allows seamless integration between #6 and #4 ported components, maintaining consistent flow rates while preventing pressure loss at connection points. This compact design weighs just 0.02 lbs and measures 2.95 inches in length, making it ideal for space-constrained tactical gear setups where every ounce and inch matters. The aerospace-grade construction ensures the adapter withstands repeated connect-disconnect cycles, vibration, and exposure to extreme temperatures.

This fitting is essential for operators maintaining modular hydraulic systems, custom rifle builds with advanced accessory integration, or any application requiring cross-compatible porting solutions. Field personnel, armorers, and equipment technicians rely on EARLS adapters for mission-critical assemblies because failure is not an option. Installation is straightforward—simply thread the adapter into existing #6 and #4 male ports using standard tools, ensuring proper torque to prevent leakage. For optimal performance, verify port compatibility and system pressure ratings before deployment.
