JIC Hydraulic Adapters (37° Flare)

Product Specification

Feature

JINGYE Fittings manufactures JIC 37° flare hydraulic adapters and custom connectors in Ningbo, China. Founded in 2008, we supply hydraulic distributors, machinery OEMs, hose and tube assembly manufacturers, and maintenance providers worldwide. Key Product Advantages: 1. Comprehensive JIC Adapter Range Twenty representative series: 1J, 1J4, 1J9, 2J, 2J9, 3J, 4J, 5J, 6J, 9J-CAP, AJ, BJ, CJ, DJ, 1JO, 1JO9, 1JN, 1JN9, 1JG, and 1JF. Options include straight connectors, 45°/90° elbows, male/female adapters, tees, crosses, bulkhead fittings, plugs, caps, and mixed-thread connections. 2. SAE J514 and ISO 8434-2 Standards JIC 37° flare connections follow SAE J514 and ISO 8434-2 where applicable. Unified inch threads support compatible tube and hydraulic fitting assemblies. The 74° included cone angle used in some catalogs corresponds to the 37° flare angle on each side. 3. Metal-to-Metal Flare Sealing Precision-machined 37° sealing faces form a metal-to-metal connection with compatible mating parts, without an O-ring at the JIC flare interface. Sealing reliability depends on correct cone geometry, surface finish, alignment, and installation. 4. Multiple Connection and Conversion Options JIC straight, elbow, tee, cross, and bulkhead configurations support compact hydraulic routing and branching. JIC-to-ORB, JIC-to-NPT, JIC-to-BSP, and JIC-to-ORFS adapters connect different interface systems, with the correct sealing method at each end. 5. Precision CNC Manufacturing JINGYE Fittings operates more than 100 CNC machines for standard and customized adapters. Machining control focuses on threads, 37° cone faces, bores, hex dimensions, elbow geometry, and consistent dimensions across batches. 6. C45 Steel and Corrosion Protection Standard adapters use C45 / SAE 1045 carbon steel with trivalent chromium zinc plating, typically 8–12 μm. Specified salt spray performance is ≥96 hours to white rust and ≥240 hours to red rust. Stainless steel 304, 316, 316L, brass, and enhanced coatings are available for suitable designs. 7. Pressure and Size Selection The catalog covers 140–420 bar working pressures and JIC threads from 7/16"-20 to 2-1/2"-12, depending on model and size. Correct selection considers tube OD, mating flare, thread dimensions, pressure rating, and the lowest-rated connection component. 8. Quality Control and Inspection Manufacturing follows an ISO 9001:2015 quality management system. Inspection includes material identification, thread gauging, 37° cone geometry, sealing surfaces, burr removal, coating condition, and critical dimensions. Pressure or leakage tests can be arranged to project requirements. 9. OEM and Custom JIC Adapters OEM manufacturing supports drawings, samples, and technical specifications. Custom options include reducers, special angles, bulkhead fittings, mixed-thread connectors, alternative materials, non-standard dimensions, and coatings. 10. Flexible MOQ and Second-Source Support Most standard models have no strict MOQ. Small-batch, mixed-SKU, volume, and long-term OEM orders are supported. In-stock items typically dispatch within 3–5 days; standard production generally takes 30–45 days. Brennan, Parker, Eaton, and other supplier part numbers can be reviewed for dimensional comparison, specification verification, custom production, and quotation. 11. Global Hydraulic Applications JIC adapters support construction equipment, agricultural machinery, mining, hydraulic power units, manifolds, cylinders, mobile hydraulics, and hose/tube assemblies. JINGYE Fittings supplies North American, European, Australian, and other markets with repeat-order and customized packaging support.
