Design and Test of a 6000 PSI Hydraulic Tube Fitting Developed to Meet the High Pressure Trend in Off-Highway Equipment 760685

This paper discusses the trend toward pressure hydraulic systems in off-highway vehicles and relates that trend to current user requirements re components, safety, and reliability information. The development of a high pressure, 6000 psi fitting, and the importance of testing during development stages of these high pressure components is emphasized using a specific design as an example. Testing and test planning are discussed. A set of nine qualifying tests is reviewed and plans for a four-way analysis of variance projected.
