Custom Hydraulic Fittings, Built to Your Blueprint.

When an off-the-shelf part is a compromise you can't afford to make, you talk to the factory. We turn OEM drawings into precision-machined reality. That's our specialty.

Your Factory Floor for OEM Components

Our catalog is a good starting point, but we know your best designs live outside of it. We are, first and foremost, a manufacturing plant with a shop full of CNCs, not a warehouse with a pick-list. Our real strength isn't just stocking parts; it's turning your engineering problem into a physical component that works, every time.

Whether you’re an OEM trying to simplify a complex manifold, or you need a non-standard fitting with a specific length, thread, or material, you’ve come to the right place. We work from your drawings. We respect your tolerances. This isn't a side-hustle for us—it's the core of what we do.

What We Can Do for You

Our production lines are built for this stuff. We can run custom jobs with the same tight quality control as our high-volume parts. Bottom line: If you can draw it, we can cut the metal.

  • 📐Modified Dimensions (Length, Hex, Threads)
  • 🔩Specialty Materials (316 SS, Duplex, etc.)
  • 🔧Complex & Integrated Manifold Blocks
  • Specialized Coatings (Zinc-Nickel, Passivation)
  • 💡Fast-Turnaround Prototyping
  • 🏷️Your Part Numbers Laser-Etched
  • 📦Custom Kitting & Packaging
  • 🤝Direct Access to Our Engineers

Our Process: From Your Print to Your Production Line

We built our process to be direct and no-nonsense, just like our parts. Here's exactly how we get a component from your desk to your assembly line:

  1. 1. Send Us the Drawing

    It starts with your RFQ. Send us your technical drawings (CAD is best, but a clear PDF works), material specs, and quantities. The more detail you give us, the faster we can give you a real answer. Start the conversation here.

  2. 2. Engineering Review (The Reality Check)

    Our guys will do a full Design for Manufacturability (DFM) review. We don't just say 'yes' or 'no.' If we see a way to tweak the design to make it stronger or save you money without compromising an ounce of performance, we'll tell you.

  3. 3. The Quote (No Surprises)

    You'll get a detailed quote with per-unit cost, any one-time tooling fees, MOQ, and a realistic lead time. We put it all on paper so there are no surprises down the road.

  4. 4. First Article: The Physical Proof

    For any new part, we machine a first-article sample. You get a real part to hold in your hands, measure, and test fit. We don't run a single production piece until you give us the official green light.

  5. 5. Production Run & In-Process QC

    Once you approve, it hits the floor. Our QC team is on it from start to finish, using the same ISO 9001 process we use for everything. Every part that comes off the line will match the one you signed off on.

  6. 6. Final Inspection & Shipping

    Your finished parts get a final, comprehensive inspection. We package them how you want them, handle the export paperwork, and get them on a boat from our factory to your door.

Shop Notes: From a Tangle of Hoses to One Smart Manifold

The Problem: A big construction OEM was using a dozen standard fittings to plumb a valve. It was a mess of potential leak points, a nightmare to assemble, and even worse to service in the field.

Our Fix: We worked with their engineers and designed a single, custom-forged manifold block that did the job of all 12 of those parts. After they approved the prototype, we moved to full production. The result: a 60% drop in potential leaks, faster assembly time, and a hydraulic system that was tougher and easier to work on. That's the kind of problem we like to solve.

Custom Hydraulic Fittings – Frequently Asked Questions

What is the minimum order quantity (MOQ) for custom fittings?

MOQs vary based on the complexity and material of the part. Simpler modifications on standard fittings may have lower MOQs, while fully custom designs from specialty alloys will require larger production runs. Contact us with your drawing for a straight answer.

Can you work from a PDF instead of a CAD file?

We can absolutely work from a detailed PDF. We'll just have to create a CAD model on our end for you to sign off on before we cut any metal.

How long does it take to get a prototype?

Prototype lead times typically range from 2 to 4 weeks, depending on material availability and machine scheduling. We will provide a firm lead time with your formal quotation.

Can you supply fittings with special plating like Zinc-Nickel?

Absolutely. We have our own in-house plating facility and offer a range of finishes, including standard Zinc, superior Zinc-Nickel for high corrosion resistance, and Electroless Nickel for chemical resistance. Tell us what it needs to survive, and we'll spec the right coating.

Do you offer private labeling or packaging per our spec?

Yes. We offer laser part marking with your brand, part numbers, or logos. We can also provide custom kitting and packaging solutions to streamline your assembly process. More information is on our quality assurance page.

Let's Make the Part You Actually Need.

Whether it’s a one-off prototype or a full production run of ten thousand pieces, our job is to give you a competitive edge by building the exact component your design demands. Stop compromising. Start manufacturing.
