Product Code:SAE AIR4789
Title:Aerospace Information Report on Evaluating Corrosion Testing of Electrical Connectors and Accessories for the Purpose of Qualification
Issuing Committee:Ae-8c1 Connectors Committee
Scope: This SAE Aerospace Information Report (AIR) establishes guidelines for evaluating the effects of corrosion testing of aluminum alloy connectors and accessories with cadmium or nickel plating.Product Code:SAE J1453
Title:Fitting--O-Ring Face Seal (Cancelled Jan 2009, Superseded by J1453/1, J1453/2, J1453/3)
Issuing Committee:Hydraulic Tube Fittings Committee
Scope:This SAE Standard covers material, dimensional, and performance requirements of steel O-ring face seal fittings for tubing and the O-ring face seal interface and nut portion of hose stem assemblies for nominal tube or hose diameters 6.35 mm (0.250 in) through 38.1 mm (1.500 in). These fittings are intended for general application and hydraulic systems on industrial equipment and commercial products, where elastomeric seals are acceptable to overcome leakage and variations in assembly procedures. These fittings are capable of providing leak-proof full flow connections in hydraulic systems operating from 95 kPa (28 in Hg) vacuum to working pressures shown in Table 1. Since many factors influence the pressure at which a hydraulic system will or will not perform satisfactorily, these values should not be construed as guaranteed minimums. For any application, it is recommended that sufficient testing be conducted and reviewed by both the user and manufacturer to assure that required performance levels will be safe. See Figure 1.The rated working pressure of a fluid conductor assembly using SAE J1453 hose stem connections or formed tube connection per Figure 32a, shall not exceed rated working pressure of the lowest rated component thereof.
