This design standard specifies the dimensions of the externally threaded fitting end to be assembled into an internally threaded fluid system port, using an elastomeric o-ring for sealing. Fitting end dimensions and o-ring sizes agree with ISO 7320-1985.
These formulae shall be used to determine drop dimensions for simple bend tube fittings utilizing flare and flareless end connection designs from 0° to 90° used in aircraft and aerospace applications. Individual design standards shall specify parameters, such as centerline bend radius (R), straight tangent length to accommodate bending equipment (X1 and X2), and nut to be used.
This SAE Aerospace Information Report (AIR) presents reference information for use in preparing detailed specifications and other documents. The intent is to have a master reference document containing frequently required tabulations of information, such as the meaning of abbreviations, the spelled out wording of acronyms, the definition of terms, etc. so that such tabulations need not be repeated in recommended practice documents describing how to prepare technical documents. This document is intended to provide references in the field of fluid system components for space applications. Space applications include spacecraft, such as satellites, space stations, launch vehicles and space shuttles, and servicing equipment and components used for ground systems and launching and for servicing in space. Fluid system components include couplings, fittings, hose and tubing assemblies.
