  • The HPA (US) 2302 Quick Disconnect (QD) Adapter provides a robust, airtight interface designed specifically for airsoft High Pressure Air (HPA) platforms. Built around the industry-benchmark US Foster 2302 / 23-2 profile, this fitting ensures broad compatibility with standard US-spec air rigs, remote lines, and secondary regulators.

    Integrated directly into the fitting body is a precision push-in pneumatic connector tailored for standard 1/4-inch air tubing (6 mm outer diameter, 4 mm inner diameter). This enables swift, tool-free hose insertion and positive lockup, allowing airsoft technicians and players to configure or repair engine airlines in seconds while maintaining a dependable high-pressure seal under dynamic movement.

    Machined from a robust combination of stainless steel and structural copper, the adapter is engineered to handle repetitive coupling cycles without galling, thread deformation, or surface corrosion. It offers reliable flow rates and complete pressure stability for demanding HPA builds.

    • US Foster 2302 Profile: Fully compatible with standard American-style HPA couplers and QD plugs.

    • Tool-Free Push-In Fitting: Instant lock and release for 6mm (1/4") airline tubing.

    • Stainless Steel & Copper Construction: Long-lasting wear resistance and structural integrity.

    • Zero-Leak Tolerances: Precision-machined sealing surfaces prevent regulator pressure drops.

    • Streamlined Form Factor: Compact profile minimizes snag hazards inside grip frames and airline sleeves.
