1.1.4.2 Tightening torques for hydraulic unions
Use the tightening torques recommended for hydraulic unions according to the tables below:
• 1 for hydraulic unions with 37° flare
• 2 for EO2 hydraulic unions
• 3 for hydraulic unions with metric straight thread
• 4 for hydraulic unions with straight thread in inches
• 5 for steel unions with sealed thread.
When a specific torque is required, this is stated in the text.
The specifications for these tightening torques apply to zinc-plated steel unions used with hoses and rigid
hydraulic pipes that ideally include straight thread unions, unions with 37° flare or unions with an "O" ring
for bosses.
These values apply to dry assemblies. If the threads are oiled, reduce the tightening torques.
