DELPHI FITTINGS
An ISO 9001 Certified Quality System You Can Audit
Our 5-step QC process and in-house testing lab ensure every hydraulic fitting, from raw material to final packaging, is fully compliant and traceable for our North American partners.
Our Philosophy: Control the Process, Control the Part.
At our factory, quality isn't a final inspection - it's the first thing we think about. We know the fittings we make are going into your critical systems, and a single failure can cost you a fortune in downtime, repairs, and reputation. We take that responsibility seriously. That's why our entire manufacturing process, from checking the raw steel that comes in the door to the final count in the shipping box, is built around one principle: owning every step.
We machine everything to the letter of the international standards - SAE, DIN, BSP, JIC. You can be damn sure that when you order a part, it will fit and perform exactly as it's supposed to. That's not a promise; it's a guarantee backed by a process you can see for yourself.
The Paperwork to Back It Up
We are an ISO 9001:2015 certified factory. For us, that's the starting line, not the finish line. This certificate is the third-party proof that we have a serious, repeatable quality management system in place. It tells you we don't just wing it; we have documented processes for everything we do, a commitment to getting better, and a focus on making sure the part you get is the part you ordered.
When you're vetting a new supplier, this is the first thing you should ask for. It’s the baseline proof that you're dealing with a professional operation, not a fly-by-night outfit.
Our 5-Step Quality Gauntlet
Every single fitting we make goes through this process. No exceptions. It’s how we find and fix problems before they ever get near your loading dock.

Step 1: Raw Material Inspection
We don't trust our steel suppliers' paperwork. Every batch of raw bar stock that comes in gets hit with our Spectrometer to verify its chemical makeup. If the steel isn't right, it doesn't even make it onto the rack.

Step 2: In-Process CNC Checks
Our operators are constantly checking parts as they come off the CNCs. We use profilometers, digital calipers, and thread gauges right at the machine to make sure every dimension, thread, and surface finish is dead-on spec.

Step 3: In-House Plating Control
This is a big one. We run our own zinc-plating line. We control the chemistry and the process to ensure a tough, consistent coating. We then test the parts in our Salt Spray Chamber to make sure they'll stand up to rust.

Step 4: Final Inspection
Finished parts get a final, rigorous shakedown. This includes 100% visual checks for any defects, thread gauge verification, and hardness testing. Nothing gets boxed until it passes.

Step 5: Shipment & Packaging QC
The last step is to make sure the right parts get in the right box. We double-check every order for accuracy and inspect the packaging to ensure your fittings arrive in perfect shape, not rattling around loose.
Laboratory & Metrology: The Proof Behind the Part
Our in-house lab is the core of our ISO 9001:2015 quality system. It gives us the independent capability to verify every critical attribute—from raw material chemistry to final part cleanliness—ensuring every fitting we ship to our North American partners meets or exceeds the required specifications.
Material & Metallurgical Analysis
- Optical Emission Spectrometer (OES): Verifies alloy grade and elemental composition against certified standards.
- Copper-Alloy Spectrometer: Dedicated OES for precise analysis of brass and other copper alloys.
- Rockwell Hardness Tester: Measures material hardness to validate heat treatment and strength class.
- Metallographic Microscope: Observes the material's microstructure and grain size to confirm proper forging and heat treatment.
- Metallographic Mounting Press & Polisher: Prepares metallurgical samples for microscopic analysis.
Dimensional & Surface Metrology
- Thread Ring & Plug Gages (GO / NO-GO): Guarantees that JIC, NPT, ORB, and other threads meet pitch diameter and form specs.
- Profile Projector / Optical Comparator: Provides non-contact measurement of complex 2D profiles and dimensions.
- Surface/Contour Profilometer: Assesses surface finish quality by measuring roughness, profile, and step height.
- Runout Tester / Concentricity Gauge: Confirms high-precision machining by measuring shaft runout and concentricity.
- Instant Vision Measurement System: Delivers rapid, automated, multi-dimension measurements, ideal for high-volume process checks.
Performance & Cleanliness Testing
- Salt Spray Test Chamber: Simulates corrosive environments to validate the performance of our in-house zinc and zinc-nickel plating.
- Cleanliness Analyzer (Particle Contamination Tester): Quantifies particulate contamination to meet stringent OEM cleanliness standards.
- Electric Thermostatic Drying Oven & Electronic Analytical Balance: Ensures precise and repeatable sample preparation for cleanliness and mass measurement tests.
Full traceability and documentation, including material certs, spectro-analysis reports, and hardness test results, are available with your shipments upon request to support your quality assurance programs.
This Is How We Build a Better Fitting.
This isn't just about passing an audit. This is about building a supply chain you can count on, backed by a process you can see. If you're tired of taking chances on quality, talk to the factory that doesn't.
