8AN/JIC Straight O-Ring Port Plug Black

The 8AN/JIC Straight O-Ring Port Plug in Black is a precision hydraulic and pneumatic system component designed for law enforcement, military, and industrial applications where fluid line integrity is non-negotiable. This straight-port adapter serves as a reliable closure or junction point in high-pressure systems, preventing fluid loss and contamination in tactical equipment, vehicle hydraulics, and weapon systems. Built for operators who demand fail-safe performance under extreme conditions, this plug is essential for maintaining system pressure and operational reliability in the field.

The 8AN port designation indicates an -8 SAE/JIC fitting size, a standard in military and commercial hydraulic applications. The o-ring seal design provides a positive, leak-free connection that withstands pressure fluctuations and thermal cycling without requiring thread sealant tape or compound, reducing installation variables and failure points. Black anodized or powder-coated finish resists corrosion and blends seamlessly into tactical systems while maintaining visibility in low-light environments. The straight configuration allows direct flow or closure capability, making it versatile across weapon mounted accessories, vehicle hydraulic systems, and portable tactical equipment requiring redundant pressure containment.

This adapter is ideal for armorers, tactical vehicle technicians, and equipment specialists building or maintaining hydraulic systems on patrol rifles, weapon platforms, or vehicle-mounted systems. Compatibility extends across all 8AN/JIC ported components, including accumulators, manifolds, and pressure regulators common in mil-spec and law enforcement equipment. Installation is straightforward—hand-tighten or torque per system specifications—and the lightweight profile (0.07 lbs) ensures negligible impact on overall system weight. Keep redundant plugs in your maintenance kit for emergency field repairs or system reconfiguration without breaking supply lines.
