Hose Assembly, Heated, 125 psig, Lined Silicone, Potable Water, Procurement Specification
This SAE Aerospace Standard (AS) covers the requirements for a flexible, lightweight, low pressure, self-extinguishing, integrally heated silicone hose assembly. The hose has a fully fluorinated fluoropolymer inner liner and is primarily intended for use in aircraft potable water systems with an environmental operating temperature range of -65 °F (-54 °C) to +160 °F (+71 °C).
Revision F changes the solid film lubricant (SFL) from AS5272 Type I to AS6449 Type I or II (lead-free). This affects the nut and nut retaining wire(s) if present.
