Frequently Asked Questions (FAQ)
Q1: What are Sin Ling's JIC fittings used for?
Sin Ling's JIC hydraulic fittings are utilized in heavy industrial and automotive systems requiring a robust 37° metal-to-metal seal capable of withstanding extreme high pressure and intense mechanical vibration.
Q2: What is the difference between JIC and ORB fittings?
JIC fittings utilize a 37° flare sealing surface for secure tube connections, whereas ORB fittings (O-Ring Boss) use straight threads combined with an O-ring for robust port sealing. Sin Ling manufactures both types to precise international standards.
Q3: Does Sin Ling offer ORB to JIC transition fittings?
Yes. As a comprehensive manufacturer, Sin Ling produces high-precision ORB to JIC fittings to facilitate seamless, leak-free transitions between ORB ports and JIC flare systems within hydraulic manifolds.
Q4: Are these hydraulic fittings compliant with SAE standards?
Yes. All of our 37 degree flare fittings are rigorously produced according to SAE J514 standards, and all O-ring boss fittings strictly follow the SAE J1926 dimensional requirements.
Q5: Are custom JIC or ORB adapters available for OEM projects?
Absolutely. Sin Ling specializes in OEM and custom CNC machining for special JIC male fittings, custom ORB hydraulic fittings, and complex transition adapters based on specific engineering drawings.
