The Parker Stratoflex 300-8D is an aerospace-grade straight flared hose fitting used with Stratoflex 111 series hydraulic hoses. It provides a secure mechanical and fluid-tight connection between flexible hoses and rigid tubing or aircraft hydraulic components.

This fitting is designed for high-reliability performance in aircraft hydraulic systems, ensuring leak-free operation under pressure, vibration, and temperature variation. It is commonly used in general aviation, business jets, and other certified aircraft hydraulic circuits where safe fluid transfer is critical.

Manufactured by Parker Stratoflex, it is made from high-strength corrosion-resistant metal and conforms to aerospace standards for hydraulic hose assemblies. The “-8” size corresponds to hose size compatibility, while the 3/4-16 thread ensures standardized installation in aircraft systems.
