Title:Hose Assembly, Polytetrafluoroethylene, Para-Aramid Reinforced, 3000 psi, 275 掳F, Heavy Duty, Aircraft Hydraulic Systems
Issuing Committee:G-3, Aerospace Couplings, Fittings, Hose, Tubing Assemblies
Scope:This document defines the requirements for heavy-duty polytetrafluoroethylene (PTFE) lined, para-aramid reinforced, hose assembly suitable for use in 275 掳F, 3000 psi aircraft systems where rapid rate pulsing and torsional/longitudinal flexing may occur in addition to normal hydraulic system loading. Size -16 and -20 are limited to +225 掳F service.
