To present a summary of the guidelines and practices presently being used by the aerospace industry for the selection of coiled tubes, flexible hoses, swivel fittings, and extension fittings in aircraft fluid systems.
This SAE Aerospace Standard (AS) defines a series of standardized tube walls to be used for high pressure hydraulic tubing. These tube walls are applicable to all homogenous tube materials (i.e., aluminum, steel, titanium) throughout a rated pressure range of 1000 to 8000 psi and a maximum rated operating temperature range of 160 to 450 °F. All future aerospace applications for which a required tube outside diameter/tube wall combination is not presently available shall be selected from the table contained herein (see Figure 1).
This specification describes a method for determining the specific gravity of tubing, fabricated from polytetrafluoroethylene, after a controlled heating and cooling cycle. The specific gravity obtained by this method is a measure of relative molecular weight of the resin. The measure, termed Relative Specific Gravity (RSG), increases with decreasing molecular weight (see 2.3).

This SAE Aerospace Information Report (AIR) presents flexure fatigue strength of tube fitting joints in the form of graphs showing applied deflection D and total calculated axial stress S versus number of cycles to failure N. The graphs have been prepared from data obtained by actual testing conducted in accordance with ARP1185.

This Aerospace Information Report (AIR) establishes flexure test procedures to determine and classify the fatigue strengths of reconnectable or permanent hydraulic tube joints. The procedure is intended for conducting flexure tests of fittings and joints for hydraulic tubing materials such as AMS 5561 steel, AMS 4944 titanium and MIL-T-7081 aluminum alloy, mounted as free-free resonant beams. Of particular advantage are the inherent simplicity of test setup, minimum restraint from a test fixture, low power requirements, short test duration, and ease of varying stress level.
