ISO 16028 Interface and Interchangeability Reference: ISO 16028 flat face hydraulic quick-action coupling interface. Mating geometry covers plug nose, groove, sealing face, socket bore and locking engagement. Mating halves must match in dimensions and performance. ISO 16028 does not specify coating durability. 3. Flat Face Valves and Low-Spillage Design Both halves use flush-face, self-closing shutoff valves. Valves open after full connection and close on separation. Flat mating faces facilitate wiping off dirt, salt and moisture before connection, helping reduce oil spillage, air inclusion and contamination. Dust caps and plugs protect disconnected ends. Standard designs require depressurized connection and disconnection. 4. Locking Sleeve and Connection Mechanism Push-to-connect socket mechanism with locking balls, spring-loaded sleeve and matching male groove. Optional sleeve safety lock and protective accessories. Protected operating parts support sleeve movement in outdoor service. 5. Working Pressure, Flow and Spillage Published comparable-series size references, in order 1/4", 3/8", 1/2", 3/4", 1", 1-1/4", 1-1/2", 2": working pressure 345/207/207/207/207/207/207/207 bar; rated flow 11.4/22.7/45.4/75.7/106/189.3/302.8/378.5 L/min; disconnect spillage 0.010/0.012/0.020/0.026/0.032/0.035/0.050/0.100 mL. Pressure drop, proof/burst and impulse ratings are configuration-specific. These figures are comparative references, not JY-FF-CR certified ratings. 6.

Feature

JINGYE Fittings offers JY-FF-CR Corrosion-Resistant ISO 16028 Flat Face Hydraulic Quick Couplings for outdoor and industrial hydraulic systems exposed to moisture, road salt and demanding service conditions. Coated-steel and stainless steel configurations combine flush-face double shutoff with corrosion protection. Key Product Advantages: 1. Eight Sizes and 16 Male/Female Models The 1/4"–2" range includes JY-FF-CR-04, 06, 08, 12, 16, 20, 24 and 32, each with P (male plug/nipple) and S (female socket/coupler) versions. Sizes are 1/4", 3/8", 1/2", 3/4", 1", 1-1/4", 1-1/2" and 2". Separate body size and port-thread specifications simplify OEM ordering, replacement sourcing and distributor inventory. 2. ISO 16028 Flat Face Interface The series uses ISO 16028-type flush-face mating geometry, with controlled male nose, locking groove, sealing face, female socket bore and locking engagement. Compatible plugs and sockets support interchangeability when interface dimensions and operating requirements match. Corrosion protection and pressure ratings are selected separately from the mating standard. 3. Low-Spillage Double Shut-Off Valves Self-closing valves in both halves open after engagement and close upon disconnection. Flat mating faces are easy to wipe before connection, helping limit hydraulic oil loss, air inclusion and contamination. Protective dust caps and plugs reduce dirt and moisture exposure when disconnected. 4. Corrosion-Resistant Coated-Steel Construction Precision CNC-machined carbon steel bodies can receive trivalent chromium zinc plating or enhanced zinc-nickel alloy coating with sealers and topcoats. Coating thickness, adhesion, thread fit and sleeve mobility are controlled. Enhanced finishes help protect hydraulic coupling surfaces in wet, outdoor and road-salt environments. 5. Stainless Steel Material Options Stainless steel 304, 316 and 316L body configurations offer an alternative material route for suitable corrosive service. Stainless components may be passivated to improve surface condition. Material selection considers exposure to chloride, moisture, washdown chemicals, hydraulic fluid and mechanical loads; coated steel and stainless steel are distinct options. 6. Salt Spray Performance and Coating Control Corrosion resistance can be specified using ISO 9227 or ASTM B117 testing. Standard trivalent zinc reference: 8–12 μm with targets of at least 96 hours to white corrosion and 240 hours to red corrosion. Enhanced systems may target 400 hours white and 750 hours red; 1,000-hour programs require defined coating and acceptance criteria. Results depend on the complete coating system and test method. 7. Seals, Valves and Locking Durability NBR and FKM elastomers and selected polyurethane sealing elements support hydraulic-fluid compatibility and wear resistance. Hardened valve parts, locking balls, sleeves and spring components provide mechanical engagement. Corrosion-resistant springs and internal hardware can be selected for demanding exposure. Standard connections require pressure relief before coupling or uncoupling. 8. Size-Specific Pressure and Flow Engineering Comparable corrosion-resistant flat-face series provide reference working pressures from 207 to 345 bar across the listed sizes, with reference flows from 11.4 to 378.5 L/min. Actual working pressure, flow loss, spillage, proof/burst limits and impulse performance depend on the configuration. Coupling rating follows the lowest-rated part of the matched assembly. 9. CNC Manufacturing and Quality Verification JINGYE Fittings operates under ISO 9001:2015 quality management. Inspections cover mating dimensions, valve stroke, locking sleeve movement, threaded ports, seal seating, material traceability and coating thickness. Agreed tests can include leakage, pressure drop, proof/burst pressure, impulse cycles, connection durability, salt spray resistance and post-exposure locking operation. 10. OEM Customization and Second-Source Supply Options include male/female halves, matched sets, BSPP/NPT ports, coated steel or stainless steel, zinc-nickel finishes, gasket compounds, protective caps, part marking and private-label packaging. Drawings, mating samples and corrosion targets support dimensional matching, OEM design adjustments, mixed-SKU purchasing and repeat orders. 11. Outdoor Machinery and Corrosive Environments Applications include excavators, skid-steer loaders, agricultural machinery, snowplows, salt spreaders, road-maintenance vehicles, mining equipment, coastal material handling, hydraulic hose assemblies and industrial MRO. These couplings suit equipment needing low-spillage service connections and corrosion protection in rain, humidity, washdown and salt-exposed conditions.
