SAE ORB Hydraulic Adapters (O-Ring Boss)

Product Specification

Feature

JINGYE Fittings is a China-based manufacturer of SAE ORB hydraulic adapters, O-Ring Boss fittings, and custom hydraulic connectors. Founded in 2008 in Ningbo, the company supplies hydraulic distributors, machinery OEMs, hose assembly manufacturers, and industrial maintenance customers worldwide. Key Product Advantages: 1. Comprehensive SAE ORB Adapter Range JINGYE Fittings offers 16 representative series: 1O, 4O, 4ON, 5O, 1JO, 1JO4, 1JO9, 1NO, 1NO9, 1BO, 1FO, 1FO9, 1CO, 1DO, 2OU, and 2OJ. Products cover straight adapters, plugs, male/female connectors, 45°/90° elbows, and conversions to JIC, NPT, BSP, ORFS, Metric, and NPSM connections. 2. SAE ORB Thread Standards SAE O-Ring Boss connections use straight threads with elastomeric sealing. Applicable standards include SAE J1926 / ISO 11926 for ORB ports and stud ends, and ASME B1.1 for unified inch threads. ORB connections differ from NPT tapered threads because sealing occurs at the O-ring interface rather than through thread interference. 3. Reliable O-Ring Boss Sealing ORB stud ends use an elastomeric O-ring to seal against a compatible SAE straight-thread port. NBR O-rings are standard, with FKM available for suitable fluids and operating temperatures. Correct O-ring selection, groove dimensions, sealing surfaces, and installation procedures help maintain leak-resistant connections. 4. Multiple Thread Conversion Options JIC-to-ORB adapters connect SAE 37° flare fittings to ORB ports. NPT-to-ORB adapters support tapered-to-straight thread conversion. ORFS-to-ORB, BSP-to-ORB, Metric-to-ORB, and NPSM connection options support different hydraulic systems. Straight and angled designs provide flexibility for equipment layouts and maintenance. 5. Precision CNC Manufacturing With more than 100 CNC machines, JINGYE Fittings manufactures standard and customized hydraulic adapters. Machining control focuses on thread accuracy, O-ring grooves, sealing faces, hex dimensions, and dimensional consistency across production batches. 6. C45 Materials and Corrosion Protection Standard adapters use C45 / SAE 1045 carbon steel with trivalent chromium zinc plating, typically 8–12 μm. Standard salt spray resistance is ≥96 hours to white rust and ≥240 hours to red rust under specified conditions. SS304, SS316, SS316L, brass, and enhanced coatings are available for suitable customized designs. 7. Pressure and Port Compatibility Selected SAE ORB adapters cover working pressures of 140–420 bar, depending on size, series, material, and sealing design. Catalog thread sizes range from 7/16"-20 to 2-1/2"-12. Pressure capability depends on the matching port, stud end, O-ring configuration, and lowest-rated connection component. 8. Quality Control and Inspection JINGYE Fittings operates under an ISO 9001:2015 quality management system. Inspection covers materials, straight-thread gauging, O-ring grooves, sealing faces, critical dimensions, burr removal, coating condition, and visual quality. Pressure and leakage tests can be arranged according to project specifications. 9. OEM and Custom SAE ORB Adapters JINGYE Fittings supports OEM production from customer drawings, samples, and technical specifications. Customization includes mixed-thread adapters, reducers, special elbows, non-standard dimensions, sealing materials, stainless steel options, and surface treatments. Technical teams can review reference numbers and drawings for manufacturing and quotation. 10. Flexible MOQ and Second-Source Supply Most standard hydraulic adapters have no strict MOQ. Small-batch, mixed-SKU, bulk, and long-term OEM orders are supported. In-stock items typically dispatch within 3–5 days; standard production generally takes 30–45 days. Customers may submit Brennan, Parker, Eaton, or other supplier reference numbers for dimensional comparison, technical verification, OEM manufacturing, and quotation. Interchangeability requires specification verification. 11. North American Applications and Global Supply SAE ORB adapters serve construction machinery, agricultural equipment, hydraulic power units, pumps, valves, manifolds, cylinders, mobile hydraulics, and industrial maintenance. JINGYE Fittings supports customers in North America, Europe, Australia, and other markets through repeat orders, customized packaging, and long-term supply programs. JINGYE Fittings combines SAE ORB sealing technology, CNC manufacturing, C45 materials, OEM customization, quality control, and flexible second-source supply for international hydraulic component procurement.
