Product Code:SAE AS1946
Title:Hose Assembly, Polytetrafluoroethylene (PTFE), Up to 450 掳F (232 掳C) and 1500 psi (10 500 KPa), Procurement Specification
Issuing Committee:G-3, Aerospace Couplings, Fittings, Hose, Tubing Assemblies
Scope:This Aerospace Standard (AS) covers the requirements for polytetrafluoroethylene (PTFE) hose assemblies for use in aerospace hydraulic, fuel, and lubricating oil systems at temperatures between -67掳F and 450掳F for Class I assemblies, -67掳F and 275掳F for Class II assemblies, and at nominal pressures up to 1500 psi. The hose assemblies are also suitable for use within the same temperature and pressure limitations in aerospace pneumatic systems where some gaseous diffusion through the wall of the PTFE liner can be tolerated. The use of these hose assemblies in pneumatic storage systems is not recommended. In addition, installations in which the limits specified by this standard, for example oxygen, shall be subject to the approval of the pruchaser.
