111-12 – Stratoflex 1500 PSI Raw Hose Sold by the Foot
Available now on the Airparts.aero Marketplace.
Overview
The Stratoflex 111-12 is a high-performance, medium-pressure aerospace hose, the industry standard for reliable fluid conveyance in a multitude of aircraft systems. Engineered by Stratoflex (a division of Parker Hannifin), the 111 series features a robust, multi-layer construction with a synthetic rubber inner tube and a high-tensile textile braid reinforcement. This design provides excellent flexibility and durability for complex routing while maintaining a constant 1500 PSI working pressure. The 111-12 is the specified hose for fabricating custom-length fuel, oil, and hydraulic lines in nearly every category of aircraft.
Key Features
- Seamless Synthetic Rubber Tube: The inner tube is constructed from a seamless, fuel-resistant Buna-N (Nitrile) synthetic rubber. This material provides excellent compatibility with a wide range of aviation fluids and maintains its integrity across a broad temperature spectrum.
- High-Tensile Textile Braid Reinforcement: Features a synthetic fiber braid reinforcement layer. This textile construction provides the high pressure rating of 1500 PSI while offering significantly greater flexibility and vibration dampening compared to steel-braided hoses.
- Durable Outer Cover: The exterior of the hose is a synthetic rubber-impregnated textile braid, providing a tough, durable layer that is highly resistant to abrasion, weather, and exposure to oils and other fluids found in the aircraft environment.
- Versatile Fluid Compatibility: Approved for use with petroleum-based hydraulic fluids (MIL-H-5606), lubricating oils (MIL-PRF-7808, MIL-PRF-23699), and hydrocarbon fuels (Jet A, 100LL Avgas).
- Industry Standard: Conforms to the stringent requirements of military and aerospace standards, making it the proven, go-to choice for fabricating medium-pressure fluid lines.

The Stratoflex 111 series hose represents a carefully engineered balance of performance and flexibility. Unlike steel-braided hoses (like the Stratoflex 193 series), which offer higher pressure ratings but are stiffer and heavier, the 111-12's textile braid reinforcement allows for a much tighter bend radius. This makes it significantly easier to route in the confined spaces of an aircraft wing or fuselage without kinking. The textile braid also provides excellent vibration dampening, absorbing the high-frequency pulses from hydraulic pumps and engines, which reduces metal fatigue on the fittings and the components they are attached to. This makes it the ideal choice for the majority of medium-pressure fluid line applications on an aircraft.
Note: This is a raw hose product. To create a functional hose assembly, it must be properly cut and assembled with the corresponding Stratoflex 111 series reusable fittings. Hose assembly fabrication must be performed by a certified A&P mechanic or qualified technician in strict accordance with the procedures outlined in Stratoflex documentation and aviation standard practices like AC 43.13-1B.
