JIC FITTINGS

JIC Hydraulic Fittings Manufacturer – 37° Flare & ORB Connectors

As a specialized JIC hydraulic fittings manufacturer, Sin Ling produces high-precision 37 degree flare fittings designed for high-pressure fluid transfer, industrial machinery, and construction equipment. Our fittings utilize a 37° metal-to-metal sealing surface, delivering excellent vibration resistance and leak-free performance in demanding hydraulic circuits.

Comprehensive Range of JIC Male & Female Fittings

Our extensive product lineup is engineered to meet SAE J514 requirements, including:
  • JIC male fittings & female flare connectors
  • Straight unions, elbows, and tees
  • Tube nuts and sleeves
  • Custom 37 degree flare fittings

O-Ring Boss (ORB) & Hybrid Adapters

We support a complete line of ORB fittings and O-ring boss fittings tailored to your drawings. These components ensure reliable sealing for systems requiring straight-thread connections compliant with SAE J1926.
Our specialized offerings include:
  • ORB hydraulic fittings (Plugs, Elbows, Port Adapters)
  • ORB to JIC fittings for smooth transitions between O-ring boss ports and JIC 37° flare connections.
All JIC and ORB components are CNC-machined in-house to ensure accurate flare geometry, thread integrity, and long-term sealing reliability.

FAQ

Q1: What are your JIC fittings used for?
Our JIC hydraulic fittings are used in industrial and automotive systems requiring a strong 37° metal-to-metal seal capable of handling high pressure and vibration.

Q2: What is the difference between JIC and ORB fittings?
JIC fittings use a 37° flare sealing surface for tube connections, while ORB fittings (O-Ring Boss) use straight threads with an O-ring for port sealing. We manufacture both types.

Q3: Do you offer ORB to JIC fittings?
Yes. As a manufacturer, Sin Ling produces ORB to JIC fittings to allow leak-free transitions between ORB ports and JIC flare systems in hydraulic manifolds.

Q4: Are your fittings compliant with SAE standards?
Yes. All 37 degree flare fittings are produced according to SAE J514, and all O-ring boss fittings follow SAE J1926 dimensional requirements.

Q5: Are custom JIC or ORB adapters available?
Absolutely. We support OEM and custom machining for special JIC male fittings, ORB hydraulic fittings, and complex transition adapters.
