Note: When choosing hydraulic  uid, the expected oil temperature extremes that will be experienced in service determine the most
suitable temperature viscosity characteristics. Hydraulic  uids with a viscosity index over 140 will meet the requirements over a wide
range of operating temperatures.

Tool to Hydraulic Circuit Hose Recommendations The chart to the right shows recommended minimum hose diameters for various hose lengths based on gallons per minute (GPM)/liters per minute (LPM). These recommendations are intended to keep return line pressure (back pressure) to a minimum acceptable level to ensure maximum tool performance. This chart is intended to be used for hydraulic tool applications only based on STANLEY tool operating requirements and should not be used for any other applications. All hydraulic hose must have at least a rated minimum working pressure equal to the maximum hydraulic system relief valve setting. All hydraulic hose must meet or exceed speci cations as set forth by SAE J517.
