124J002-4CR-0240 – Stratoflex FAA-PMA Teflon Hose Assembly
Available now on the Airparts.aero Marketplace.
Overview
The Stratoflex 124J002-4CR-0240 is a premier, FAA-PMA approved, medium-pressure Teflon hose assembly, representing the industry standard for high-performance fluid conveyance in modern aircraft. Manufactured by Stratoflex, a division of Parker Hannifin, the 124 series hose is engineered for absolute reliability in demanding aerospace environments. This 24-inch assembly features a conductive Polytetrafluoroethylene (PTFE) inner tube, reinforced with a stainless steel braid, and terminated with corrosion-resistant steel fittings. It is the definitive choice for critical fuel, oil, hydraulic, and pneumatic applications where performance, temperature range, and fluid compatibility are paramount.
Key Features
- Conductive PTFE Inner Tube: The core of the hose is a seamless, smoothbore tube made from extruded, carbon-impregnated PTFE (Teflon). This conductive design safely dissipates static electricity generated by fluid flow, preventing dangerous electrostatic discharge events, especially in fuel systems.
- Corrosion-Resistant Steel Braid: A single braid of high-tensile, 300-series Corrosion Resistant Steel (CRES) wire is woven over the PTFE tube. This reinforcement provides a 1500 PSI operating pressure rating and protects the inner tube from abrasion, impacts, and damage.
- Superior Fluid & Temperature Compatibility: The chemically inert PTFE inner tube is impervious to virtually all aviation fluids, including petroleum and synthetic-based oils, hydraulic fluids (including Skydrol), and all types of fuel. It maintains its integrity and flexibility across an extremely wide operating temperature range of -65°F to 450°F.
- Low Profile & High Flexibility: The smoothbore design provides lower pressure drop and higher flow rates compared to convoluted hoses. The entire assembly is lightweight and offers a small bend radius, making it ideal for complex routing in confined spaces.
- FAA-PMA Certified: As an FAA-PMA approved assembly, it meets the highest standards for material, manufacturing, and performance, making it a fully airworthy component for installation on type-certified aircraft.

The Stratoflex 124 hose series represents a significant technological advantage over traditional rubber hoses. The smoothbore PTFE inner tube has an extremely low coefficient of friction, which not only improves flow efficiency but also prevents the accumulation of coke, sludge, and other deposits that can form in high-temperature oil lines. The conductive nature of the liner provides a continuous path to ground (through the CRES braid and end fittings), preventing the buildup of static charge from fluid flow, which can reach levels high enough to create an ignition source or interfere with sensitive avionics. This combination of material science and design makes it a foundational component of modern, safe aircraft fluid systems.
Note: This is a flight-critical component. Installation must be performed by a certified A&P mechanic. The hose must be routed in accordance with the aircraft maintenance manual, ensuring it is properly supported with clamps and is not subject to twisting, chafing, or bending tighter than its specified minimum bend radius. The end fittings must be torqued to the correct value.
