AS4897
This SAE Aerospace Standard (AS) covers the requirements for polytetrafluoroethylene (PTFE) hose assemblies for use in aerospace fuel and lubricating oil systems at temperatures between -67 and 450°F and at operating pressures per Table 1. 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 herein are exceeded, or in which the application is not covered specifically by this document, for example oxygen, shall be subject to the approval of the purchaser.

ARP4698A
This SAE Aerospace Recommended Practice (ARP) is intended as a guide for choosing a minimum wall thickness of tubing, based only on pressure, for use with welded tube fitting ends that have a “tube wall code” covering a range of tube wall thicknesses. These wall thicknesses are based on burst pressure with an arbitrary additional safety factor. If the weld fitting user has already established the required minimum wall thickness for given performance conditions, this guide does not apply.
