| Params | Product Name: ISO 5675 Poppet Valve Agricultural Quick Couplings Manufacturer: JINGYE Fittings (Ningbo Jingye Fluid Fittings Co., Ltd.) Series: JY-AG-PV; ISO 5675 agricultural hydraulic quick coupling family. Construction: Carbon steel male tips and female sockets with manual-sleeve ball locking and spring-loaded poppet double shutoff. 1. Product Series and Nominal Sizes JINGYE Series: JY-AG-PV. Published coupling-set offering: 1/4"–1" NPT/BSP, Pioneer-type agricultural profile. Common nominal sizes: 1/4" (DN6.3), 3/8" (DN10), 1/2" (DN12.5), 3/4" (DN20) and 1" (DN25). Specify male tip, female coupler or matched pair, nominal body size and hydraulic port thread separately. 2. ISO 5675 Interface and Pioneer-Type Matching Reference: ISO 5675:2021 for general-purpose agricultural hydraulic couplings. Mating geometry includes plug tip diameter and profile, retaining groove, socket bore, sealing contact and locking-ball engagement. The 1/2" ISO 5675 universal tractor tip is widely used in North American agricultural hydraulics. Parker Pioneer 4000, Faster NS/NV and Safeway agricultural products provide comparison references; mating fit must be confirmed by exact size and profile. 3. Spring-Loaded Poppet Double Shutoff A conical spring-loaded poppet in each half opens during full engagement and closes when disconnected, helping retain hydraulic oil in tractor and implement lines. Precision valve seats, springs and O-rings support internal and external sealing. Poppet valves differ from ball-valve agricultural couplers and flat-face low-spill designs; some fluid spillage and air inclusion can occur during disconnection. 4. Manual Sleeve and Ball-Locking Mechanism The female socket typically uses a manually retracted sliding sleeve and hardened radial locking balls to engage the male tip groove. Spring return holds the coupling halves together after full insertion. Inspect ball retention, sleeve stroke, plug groove and connection force. Manual-sleeve versions are distinct from double-acting push-pull, breakaway and dedicated connect-under-pressure arrangements. 5. Carbon Steel Working Pressure and Strength JINGYE's ISO 5675 poppet reference table lists 1/4" 345 bar (5,000 psi), 3/8" and 1/2" 276 bar (4,000 psi), and 3/4" and 1" 207 bar (3,000 psi). Comparable Parker Pioneer 4000 designs use a separate 3,000 psi rating across five body sizes. The selected coupling design governs working, proof, burst and impulse performance; interchangeable geometry does not imply equal pressure ratings. 6. Rated Flow and Pressure Drop JINGYE's published poppet-type size references: 1/4" 3 US gpm (11.4 L/min); 3/8" 6 gpm (22.7 L/min); 1/2" 12 gpm (45.4 L/min); 3/4" 28 gpm (106 L/min); 1" 50 gpm (189.3 L/min). Evaluate pressure drop at required flow using oil viscosity, temperature and valve passage geometry. Distinguish rated flow from peak or maximum flow and verify flow through the complete matched set. 7. Materials, Seals, Surface Protection and Temperature Precision CNC-machined carbon steel bodies, plugs and sleeves combine with hardened steel locking balls, poppet valves and return springs. Standard NBR (Buna-N) seals suit compatible mineral hydraulic oils; optional FKM or selected EPDM compounds depend on fluid compatibility. Typical NBR reference temperature: -20°C to +100°C. Trivalent chromium zinc plating, typically 8–12 μm, and optional enhanced zinc-nickel finishes protect carbon steel. 8. Hydraulic Ports and Dimensional Inspection Common ends include BSPP (G), BSPT, NPT/NPTF and selected SAE ORB ports. Hydraulic end-port threads are independent of the ISO 5675 mating interface. Inspect plug nose, groove, sleeve diameter, socket length, connected length, hex dimensions, port gauges, poppet stroke and sealing surfaces. For 1/2" tractor replacement tips, confirm the actual universal-tip profile rather than identifying compatibility from nominal thread size alone. 9. Quality Control and Functional Testing Quality Management: ISO 9001:2015. Production checks include CNC dimensions, material grade, induction-hardened wear parts, locking-ball fit, sleeve operation, seal assembly, coating thickness and internal cleanliness. Agreed verification may cover mating interchange, internal/external leakage, pressure drop, proof/burst pressure, impulse cycles and repeated connection cycles. Standard designs are depressurized before coupling unless separately equipped for residual pressure. 10. Agricultural Applications and OEM Procurement Applications: tractor rear remotes, hydraulic loaders, balers, seed drills, sprayers, harvesters, farm implements, mobile hydraulics and hydraulic hose assemblies. Supply options include male tips, female couplers, matched sets, BSP/NPT/SAE ports, seal compounds, protective caps, marking and private-label packaging. JINGYE Fittings supports drawings, mating samples, mixed-SKU supply, replacement parts, OEM production and second-source development. | Material | Body Materials: Precision CNC-machined carbon steel (C20/C45 options by component) for ISO 5675 male tips, female sockets and sliding locking sleeves.
