AE3663163E0240 – Textron Aviation OEM Teflon Hose Assembly
Available now on the Airparts.aero Marketplace.
Overview
The AE3663163E0240 is a genuine OEM, high-performance, medium-pressure Teflon hose assembly, manufactured in strict accordance with the SAE Aerospace Standard AS3663. This is not a standard rubber hose; it is an advanced fluid conveyance solution engineered for the most demanding applications in modern turbine and high-performance aircraft, including those manufactured by Textron Aviation. The assembly features a smoothbore, conductive Polytetrafluoroethylene (PTFE) inner tube, reinforced with a stainless steel braid, providing exceptional performance across a wide temperature range and compatibility with virtually all aviation fluids.
Key Features
- Conductive PTFE Inner Tube: The core of the hose is a seamless, smoothbore tube made from extruded Polytetrafluoroethylene (PTFE), commonly known as Teflon. It is impregnated with carbon, making it conductive to safely dissipate static electricity generated by fluid flow, a critical safety feature for 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 the high pressure rating and protects the inner tube from abrasion and damage.
- Superior Fluid & Temperature Compatibility: The PTFE inner tube is chemically inert and impervious to all petroleum and synthetic-based aviation fluids, including hydraulic fluid (Skydrol), jet fuel, and engine oil. It maintains its flexibility and strength in an extremely wide operating temperature range.
- Low Profile, High Performance: The smoothbore design provides lower pressure drop and higher flow rates compared to convoluted bore hoses. The entire assembly is lightweight and has a small bend radius, making it ideal for complex routing in tight spaces.
- OEM Specification: As a component specified by Textron Aviation, it guarantees the correct length, end fittings, and pressure rating required for a specific application on their certified aircraft, ensuring an airworthy and reliable installation.

Why Choose AE3663163E0240?
A ruptured hydraulic or fuel hose in flight constitutes a critical emergency. The AE3663163E0240 hose assembly is engineered to provide the highest level of safety and reliability. Its PTFE and stainless steel construction prevents deterioration from age or fluid exposure, a common failure mode for rubber hoses. Using a genuine OEM-specified hose guarantees that the length and fitting orientation are perfect for the intended installation, preventing chafing and stress that could lead to premature failure. For flight-critical fluid systems, there is no substitute for certified, high-performance hose assemblies.

The conductive nature of the AE3663163E0240's PTFE inner tube is a critical safety feature. As non-conductive fluids like jet fuel flow at high velocity through a hose, they can generate a significant static electrical charge through fluid friction, a phenomenon known as "flow electrification." In a non-conductive hose, this charge can build up to thousands of volts and then discharge as a spark through the hose wall, potentially igniting the fuel vapors. The carbon-impregnated PTFE liner in this hose assembly provides a safe path for this static charge to bleed off to the grounded end fittings, preventing static buildup and eliminating the risk of an electrostatic discharge event.
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.
