This SAE Information Report is intended to provide design guidance in the selection of steel tubing and related tube fittings for general hydraulic system applications. The information presented herein is based on tubing products which conform to SAE and ISO standards listed in the reference section. The purpose of this document is to provide nominal reference working pressures for selecting tube material, OD size and wall thickness for given hydraulic system working pressures based on desired 4 to 1 design factor of the applicable burst pressure rating.
