Inventory & Lead Time You Can Plan On
We confirm MOQ and lead times upfront, then we hit our dates. We manage production schedules for our OEM partners to ensure your assembly line never stops waiting for a fitting.

Your Direct Line to a 290,000 sq. ft. Hydraulic Fitting Factory
Since 1998, Delphi Fittings (legally Yuhuan Dongfei Machinery Co., Ltd.) has been the factory, not the middleman. Trust isn't built with slogans; it's earned with calipers and an in-house plating line. When you partner with us, you're dealing directly with the ISO 9001 certified institution that machines, tests, and ships your components. Learn more about our story and our facility.
About the Name: Why "Delphi"?
In ancient Greece, the Oracle at Delphi gave clear, unambiguous answers to high-stakes questions. An engineer with a blueprint is in the same boat—you can't afford to guess if a fitting will hold 6,000 PSI. We chose the name Delphi because our job is to provide that certainty. Every fitting we machine is a clear, reliable component that does its job, every time. No guesswork. Just the right answer, forged in steel.

The Factory Floor: The Source of Your Competitive Edge
Factories don’t usually impress seasoned buyers - but ours earns repeat POs. Walk the floor and you’ll see 200+ machines (including 100+ CNC lathes), bright work areas, and parts moving with discipline, not chaos. It’s not flashy. It’s controlled. That’s the difference between a supplier that ships once, and one you can reorder from for years.
We don’t chase capacity - we built it so you can plan supply. With 200+ machines, in-house plating, and lot-based QC, we hold specs steady from batch to batch. If a part doesn’t pass inspection, it doesn’t ship. You get fittings that match spec, thread clean, and seal right - without the rework and returns that quietly eat margin.
Plating? Ours happens 50 feet from where the parts are made. No trucks. No outsourcing. No guessing. That’s why when customers crack open a box from Delphi, they know what they’re holding: parts that hold pressure, hold up under salt spray, and hold your name on the line.
Vetted by the Partners Who Depend On Us
We're not just a supplier; we're a critical link in our partners' supply chains. Here's what they have to say about working directly with the factory floor.
"We brought Delphi in as a secondary source for our top-moving hydraulic fitting SKUs. Batches have been consistent, threads are clean, and reorder communication is straightforward - the kind of supplier you can keep on an approved list."
