Stop Leaks Before They Start

According to our CNC machining knowledge base, CNC machining produces strong and accurate parts with simple or complex geometries, and it is especially effective for connectors and fittings that demand consistency and repeatability. That precision is what keeps hydraulic systems leak-free.

When a thread is out of class or a sealing surface is imperfect, your fittings fail under pressure. CNC Works AI delivers precision-engineered adapters, couplings, flanges, and quick-connects with tight tolerances and smooth finishes—so your assemblies seal the first time, every time.

  • Class-fit threads per UNF, BSPP, NPT, and metric standards
  • Smooth sealing surfaces and controlled surface roughness
  • Consistent repeatability for high-volume connector runs
  • Full inspection reports and material certs with every order

Frequently Asked Questions

CNC Works AI produces UNF/UNC, BSPP, BSPT, NPT/NPTF, metric, and JIC threads on hydraulic fittings. Thread fit classes include 2B/3B for inch threads and 6H/6g for metric threads. Thread milling is available for complex or high-value connectors where tap breakage is a concern.

Hydraulic fittings are manufactured for pressure ratings from 3,000 PSI (210 bar) standard duty to 10,000 PSI (700 bar) high-pressure applications. Every fitting lot is pressure-tested to 1.5× working pressure when required by the customer's specification.

According to our CNC machining knowledge base, programmed processes ensure all copies of components meet the same standard, which is critical for mass-produced connectors and fittings. CNC Works AI combines programmed toolpaths with in-process inspection and final CMM verification to maintain consistency from the first part to the ten-thousandth.

316L stainless steel is recommended for marine, chemical, and food-grade environments due to its superior corrosion resistance. Brass 360 is ideal for low-pressure, high-machinability applications. Carbon steel 1215 with plating is common for cost-sensitive industrial fittings.

Recommended finishes include electroless nickel per AMS 2404 for uniform hardness and corrosion protection, passivation per ASTM A967 for stainless steel, hard anodize for aluminum, and zinc or cadmium plating for carbon steel. Finish selection depends on the operating fluid, pressure, and environment.

Yes. CNC Works AI machines SAE J518 split-flange halves, flange heads, and counter-bore bodies for high-pressure hydraulic lines. Flange sealing surfaces are machined flat and bolt holes are held to true-position tolerances for reliable gasket compression.

Standard prototypes ship in 5-7 business days. Rush service is available in 7–15 days for urgent projects. Production volumes of 1,000+ units typically deliver within 2-4 weeks. We maintain raw material stock for common fitting alloys to reduce lead times.

CNC Works AI is ISO 9001:2015 certified for quality management, AS9100D certified for aerospace applications, and ISO 13485 certified for medical devices. The quality lab is equipped with CMM, optical comparators, surface roughness testers, and thread gages.
