Overview
Hydraulic tube bending is a precision fabrication process that produces rigid hydraulic lines capable of operating under demanding pressure and environmental conditions. Unlike flexible hose assemblies, rigid tubing provides stable routing, consistent support, and durable fluid conveyance in applications where dimensional accuracy and long-term reliability are critical.
PSI Hydraulics manufactures custom and replacement hydraulic tubing for industrial equipment, hydraulic power units, mobile machinery, and OEM hydraulic systems. Whether reproducing an existing tube assembly or fabricating tubing for a new installation, each bend must be produced with careful attention to dimensional accuracy, routing requirements, and compatibility with surrounding hydraulic components.
Successful tube bending extends beyond achieving the correct bend angle. Bend radius, wall integrity, end connections, and routing all influence hydraulic system performance. Improperly formed bends may restrict flow, introduce unnecessary stress into the tubing, complicate installation, or accelerate fatigue failures caused by vibration and cyclic loading. Maintaining smooth bend geometry and accurate routing helps preserve system performance while reducing unnecessary mechanical stress on fittings and connected components.
A replacement tube needs to fit the equipment as well as the drawing. PSI can reproduce an existing assembly or fabricate a new line, then bend and fit tubing onsite as part of an installation when the equipment layout calls for it. If you need PSI to source or custom-manufacture the tubing and install the complete run, see our Hydraulic Tubing service.

Why Choose PSI
Hydraulic tubing must do more than connect two points within a hydraulic system. Proper routing, bend geometry, and dimensional accuracy influence installation, serviceability, vibration resistance, and the long-term integrity of the hydraulic circuit. A tube assembly that fits correctly while minimizing mechanical stress helps reduce maintenance requirements and supports reliable hydraulic operation.
PSI Hydraulics approaches tube bending with an understanding of the complete hydraulic system rather than the tubing alone. By considering routing, component accessibility, connection geometry, and operating conditions throughout the fabrication process, we manufacture hydraulic tube assemblies that integrate efficiently into industrial and OEM equipment while supporting dependable system performance.
Frequently Asked Questions
Can existing hydraulic tube assemblies be reproduced if drawings are unavailable?
Yes. Existing tube assemblies can often be evaluated and reproduced through reverse engineering, allowing replacement tubing to match the original routing and connection geometry.
Why is bend radius important in hydraulic tubing?
Maintaining an appropriate bend radius helps preserve tube wall integrity, reduces stress concentrations, minimizes flow restrictions, and improves long-term fatigue resistance during operation.
How does tube routing affect hydraulic system reliability?
Proper routing helps prevent vibration-related failures, protects tubing from mechanical interference, maintains adequate clearance around moving components, and improves accessibility for future maintenance.
Can custom hydraulic tubing be manufactured for equipment modifications?
Yes. Custom tube assemblies can be fabricated for new hydraulic installations, equipment upgrades, system modifications, or replacement applications where standard tubing configurations are not suitable.
Can PSI bend hydraulic tubing onsite?
Yes. When a tube must be fitted to the equipment’s actual layout, PSI can bend and route it onsite as part of a hydraulic tubing installation. PSI also fabricates replacement and custom tube assemblies for projects that can be measured and built in advance.
What information is needed to fabricate replacement hydraulic tubing?
Engineering drawings are preferred, but existing tube assemblies, dimensional measurements, photographs, connection specifications, and equipment information can often be used to reproduce hydraulic tubing accurately.
How is tube fit verified before installation?
Tube assemblies are fabricated to maintain the required bend geometry, routing dimensions, and connection locations so they integrate correctly with the surrounding hydraulic components and support proper installation.
