Established in 2008 in Ningbo, China, the company serves hydraulic hose assembly manufacturers, distributors, machinery OEMs, and maintenance suppliers worldwide. Key Product Advantages: 1. Comprehensive 19-Series Product Range JINGYE Fittings supplies 87311, 87331, 87341, 87361, 87391, 87611, 87631, 87641, 87661, 87691, 87313, 87393, 87613, 87693, 87913, 87993, 87318D, 87398D, and 87698D Series. Configurations include straight, 45° and 90° elbows, alternative hose tails, and special flange connections for different hydraulic assembly requirements. 2. SAE Code 61 and Code 62 Connections The 873 Series covers SAE Code 61 flange fittings, commonly known as the 3000 PSI series. The 876 Series covers Code 62, commonly known as the 6000 PSI series. Connections follow applicable SAE J518 and ISO 6162-1 / ISO 6162-2 dimensional requirements. Actual pressure ratings depend on fitting size and assembly specifications. 3. High-Pressure and Interlock Flange Options The 87913 and 87993 Series cover special 9000 PSI-class flange configurations for compatible high-pressure interlock hose assemblies. The 87318D, 87398D, and 87698D Series offer additional specialized flange designs. Matching hose inserts, ferrules, and validated crimp specifications are required. 4. Multiple Hydraulic Hose Compatibility Selected fittings support compatible SAE 100R1/R2/R12/R13, EN 853 1SN/2SN, and EN 856 4SP/4SH braided and spiral hydraulic hoses. Compatibility depends on hose dimensions, fitting insert design, ferrule selection, and approved crimping specifications. 5. O-Ring Flange Sealing System SAE flange connections use O-ring sealing between the flange head and hydraulic port. NBR seals are commonly used, with FKM options for suitable operating conditions. Correct O-ring dimensions, flange geometry, clamps, fasteners, and tightening procedures support reliable connections. 6. Precision CNC Manufacturing With more than 100 CNC machines, JINGYE Fittings supports precision manufacturing of flange heads, O-ring grooves, hose tails, elbows, and sealing surfaces. Dimensional inspection and machining control help maintain consistent quality across standard production and customized orders. 7. Materials and Corrosion Resistance Standard carbon steel fittings feature trivalent chromium zinc plating, typically 8–12 μm, with ≥96 hours to white rust and ≥240 hours to red rust under specified salt spray conditions. Stainless steel 304, 316, 316L, enhanced coatings, and customized finishes are available according to product requirements. 8. Quality Control and Engineering Verification JINGYE Fittings operates under an ISO 9001:2015 quality management system. Quality control covers material inspection, flange dimensions, O-ring grooves, sealing faces, burr removal, and coating condition. Connection compatibility, sealing performance, and pressure requirements are evaluated according to applicable specifications. 9. OEM and Custom SAE Flange Fittings JINGYE Fittings supports OEM manufacturing from customer drawings, samples, and technical specifications. Customization includes special flange dimensions, elbow configurations, hose tails, materials, coatings, and product identification. Reference part numbers and drawings can be submitted for dimensional comparison, technical evaluation, and quotation. 10. Flexible MOQ and Second-Source Supply Most standard hydraulic fittings have no strict MOQ. JINGYE Fittings supports small-batch purchasing, mixed-SKU orders, bulk production, and long-term OEM supply. In-stock items typically dispatch within 3–5 days; standard production generally requires 30–45 days. Alternative and second-source supply is supported following dimensional and performance verification. 11. International Applications and Long-Term Cooperation SAE flange hose fittings support construction machinery, mining equipment, agricultural machinery, industrial hydraulic power units, mobile hydraulics, and hose assembly manufacturing. JINGYE Fittings serves Europe, North America, Australia, and other international markets, supporting repeat orders, customized packaging, and long-term procurement programs. JINGYE Fittings combines SAE Code 61 and Code 62 flange connections, special high-pressure designs, precision CNC manufacturing, OEM customization, quality control, and flexible supply capabilities for international hydraulic equipment and hose assembly customers.
