SAE J517:2017 pdf free.Hydraulic Hose
Hydraulic hose is rarely used without connectors. Hose with connectors attached are commonly referred to as hose assemblies. The general and dimensional standards for hydraulic hose connectors are contained in SAE J516. SAE J516 connectors are identified by a code system as specified in SAE J846. The hose code, in accordance with SAE J846, for use with their respective connectors is shown in Appendix B.
Hose assemblies may be fabricated by the manufacturer, an agent for or customer of the manufacturer, or by the user.Fabrication of permanently attached connectors to hydraulic hose requires specialized assembly equipment. Field attachable connectors (screw style and segment clamp style) can usually be assembled without specialized equipment although many manufacturers provide equipment to assist in this operation.
SAE J517 hose from one manufacturer is usually not compatible with SAE J516 connectors supplied by another manufacturer. It is the responsibility of the fabricator to consult the manufacturer’s witten assembly instructions or the manufacturers directly before intermixing hose and connectors from two manufacturers. Similarly, assembly equipment from one manufacturer is usually not interchangeable with that of another manufacturer. It is the responsibility of the fabricator to consult the manufacturer’s written instructions or the manufacturer directly for proper assembly equipment. Always follow the manufacturer’s instructions for proper preparation and fabrication of hose assemblies.
The test requirements for each 100R-series hose are detailed in this document. Specific procedures for conducting each test are contained in SAE J343. The specified tests provide a baseline for performance capability of a hose assembly under controlled laboratory conditions. Hydraulic systems seldom duplicate these test parameters precisely. The hydraulic designer shall consider the system demands on the hose assembly and correlate those demands with the specified requirements, with particular concern for the frequency and amplitude of pressure fluctuations. Rapid pressure cycling with a return to zero accelerates fatigue failures.SAE J517 pdf free download.
