CUSTOM FABRICATION

Custom Hydraulic Components Fabrication

Engineered-to-Spec Hydraulic Assemblies — Built, Modified, and Tested Under One Roof

When a catalog part doesn't fit your envelope, pressure class, or duty cycle, the answer is to build the component the application needs. HSC machines, modifies, assembles, and pressure-tests in-house — from a single pump shaft change to a complete hydraulic power unit. Backed by the HSC Engineering Center since 1947.

Built to your drawing, pressure class, and port configuration — then functionally tested before it leaves the floor.
Scope ranges from a single pump shaft change to a fully engineered, tested hydraulic power unit.
Machining, welding, tube bending, and assembly happen under one roof — fewer handoffs, tighter tolerances.
Backed by the HSC Engineering Center, led by a Certified Fluid Power Engineer (CFPE).

FABRICATION SCOPE

What Custom Hydraulic Component Fabrication Covers

Custom fabrication is a set of capabilities that let you specify a hydraulic component by function, not part number. Builds combine machining, welding, tube and hose fabrication, modification, assembly, and verification testing — coordinated by one team.

Common build types include:

Custom and modified hydraulic power units built to your flow, pressure, and reservoir requirements, with the valving and controls your circuit calls for
Pump and motor modifications — shaft changes, port conversions, and mounting adaptations to match your installation
Custom cylinder configurations and rebuilds to your bore, stroke, mounting, and seal specifications
Manifold and valve assemblies plumbed, set, and tested to your circuit
Hose assemblies, cut-and-weld work, and tube bending fabricated to print
Electro-hydraulic and proportional control integration for new builds and retrofits

Single Point of Accountability

Cut and weld, tube bending, hose assembly, and machining all happen in one facility. Fewer handoffs mean tighter tolerances and one team behind every build.

Verified Before It Ships

Critical assemblies are pressure- and function-tested in-house against spec before they leave the floor. What arrives at your dock is verified — not something to diagnose on the line.

BUILT TO SPEC

Built to Spec, Verified Before It Ships

Every build starts with your requirements, not our assumptions. We confirm what the component has to do — and the envelope it has to do it in — before a single part is machined.

We build from:

  • Operating pressure and flow, including peak and continuous duty
  • Port sizes, thread standards, and mounting configurations
  • Envelope, weight, and installation constraints
  • Fluid type, temperature range, and filtration requirements
  • Duty cycle, expected load, and cycle frequency
  • Drawings, schematics, or a sample of the part being replaced

From there, we machine, modify, and assemble to those locked specifications. Critical builds are pressure- and function-tested before shipment, so the component arrives verified against the spec.

REAL-WORLD APPLICATIONS

Where Custom Fabrication Earns Its Keep

After two decades of building and troubleshooting hydraulic systems, the pattern holds: custom fabrication pays off wherever a standard component forces a compromise.

Obsolete or Unavailable Parts

Recreate or adapt a component when the original is discontinued or lead times are unworkable. We work from drawings, samples, or the part being replaced.

Tight Installation Envelopes

Build to fit the space the machine actually has. Mounting, port location, and envelope follow your installation — not what's on the shelf.

Demanding Duty Cycles

Specify materials, seals, and pressure ratings to the real load — engineered for the work your machine actually does.

OEM and Production Programs

Repeatable, documented builds for OEMs and multi-unit fleets — locked specs, consistent results, one point of accountability.

System Upgrades and Retrofits

Integrate modern valving and electro-hydraulic controls into existing machinery — extending equipment life without a full system replacement.

The goal is the same in every case: a component engineered to the work, not an application bent to fit the part.

Custom Hydraulic Fabrication FAQs

What can Hydraulic Supply Company fabricate?

Anything from a pump shaft change to a complete, tested hydraulic power unit — including motor modifications, custom cylinder configurations, manifold and valve assemblies, hose and tube fabrication, and full power-unit builds with controls integration.

Do you build to our drawings and specifications?

Yes. Every build works from your approved drawings, schematics, or a sample part — plus your pressure, flow, port, and envelope requirements. Specs are confirmed before fabrication begins.

Can you modify an existing component instead of building new?

Often, yes. Shaft changes, port conversions, mounting adaptations, and cylinder rebuilds are routine. We'll also tell you when a purpose-built component is the better long-term answer.

Are custom components tested before delivery?

Critical assemblies are pressure- and function-tested in-house against spec before they ship, so the component is verified before it reaches your equipment.

Can your engineers help if we do not have a complete specification?

Yes. The HSC Engineering Center supports component selection through full system design — sizing pumps, valves, and actuators to your loads and operating conditions.

What industries do you support?

Manufacturing, heavy and mobile equipment, construction, agriculture, marine, and industrial automation — essentially any operation running hydraulic or electro-hydraulic systems.

How do I start a custom fabrication project?

Send your drawings or a sample part, operating requirements, and timeline. Our team will scope the build.
