Brass ISO 7241-B Hydraulic Quick Couplings

Product Specification

Feature

JINGYE Fittings supplies Brass ISO 7241-B Hydraulic Quick Couplings for industrial fluid transfer and suitable-pressure hydraulic circuits. The proposed JY-ISOB-BR family combines precision-machined brass bodies, Series B mating geometry, poppet-valve double shutoff and ball-locking engagement. Key Product Advantages: 1. Brass Series B Product Range The proposed JY-ISOB-BR series covers brass male plugs, female sockets and matching sets. Common ISO B reference sizes include 1/8" (DN5), 1/4" (DN6.3), 3/8" (DN10), 1/2" (DN12.5), 3/4" (DN20) and 1" (DN25). Body size, port thread and coupling half are selected separately. The series identifier is proposed for JINGYE product development. 2. ISO 7241-1 Series B Mating Compatibility The Series B interface controls male plug nose, engagement groove, socket entry, locking-ball position and sealing alignment. Matching dimensions support use with suitable ISO 7241-1 Series B counterparts. Series B is different from ISO 7241-A and ISO 16028 flat-face couplings; mating geometry alone does not establish equal pressure or temperature ratings. 3. Precision-Machined Brass Construction Selected brass or copper-alloy bodies offer good machinability and corrosion resistance in many compatible industrial fluids. CNC turning controls port threads, plug profiles, valve seats and socket dimensions. Brass grade, wetted components and seals are selected for water quality, coolant formulation, hydraulic fluid and operating environment. 4. Poppet-Valve Double Shutoff Spring-loaded conical poppets in the plug and socket open when fully connected and close after separation, helping retain fluid in both disconnected lines. Precision valve seats and elastomer seals support leak control. Conventional poppet couplings can release some liquid during disconnection and are not equivalent to low-spillage flat-face couplings. 5. Ball-Locking Sleeve Engagement A sliding sleeve and locking balls secure the male plug within the female socket. Groove fit, sleeve stroke, spring return and poppet travel contribute to repeatable engagement. Stainless steel locking balls and springs can be selected for corrosion resistance. Normal coupling and uncoupling require pressure relief unless a specialized pressure-connection design is supplied. 6. Application-Specific Working Pressure A comparable ZY-B1 brass ISO B series lists 70 bar (7 MPa) working pressure across its 1/8"–1" sizes. Other engineered brass ISO B designs, including Stucchi IRBO, publish higher ratings up to 200 bar. These are distinct industry references, not confirmed JY-ISOB-BR ratings. Working, proof and burst pressures must be specified for the selected size and construction. 7. Flow Capacity and Hydraulic Resistance Comparable brass Series B nominal flows span approximately 3.8 L/min at DN5 to 190 L/min at DN25; intermediate reference points include DN10 23 L/min, DN12.5 45.5 L/min and DN20 106 L/min. Pressure drop varies with valve passages, fluid viscosity, temperature and flow. Nominal flow, maximum flow and acceptable pressure loss are evaluated separately. 8. Seal Materials and Fluid Compatibility NBR (Buna-N) is an option for compatible mineral oils and selected water-based fluids; FKM supports specified fluids and elevated temperatures, while EPDM suits certain water-based services. Published reference seal ranges include NBR -20 to +100°C and FKM -20 to +180°C. Final temperature limits depend on the complete assembly, medium and seal compound; brass is not suitable for every chemical or water chemistry. 9. Surface Finish and Quality Inspection Natural machined brass and optional nickel plating offer different finish choices. Manufacturing inspection checks alloy grade, ISO mating dimensions, threads, poppet seats, locking-ball retention, sleeve travel, seal installation and internal cleanliness. JINGYE Fittings operates under ISO 9001:2015 quality management; agreed tests include fit, leakage, pressure drop, proof/burst pressure and repeated coupling cycles. 10. OEM Configuration and Second-Source Support Options include plug-only, socket-only or paired supply, BSPP (G) and NPT ports, specified copper alloys, seal compounds, nickel plating, protective caps, marking and private-label packaging. Customer drawings and existing mating samples support dimensional matching. JINGYE Fittings supports sample evaluation, mixed-SKU procurement, custom machining, OEM programs and alternative-source purchasing. 11. Industrial Fluid and Equipment Applications Brass Series B quick couplers serve compatible oil, water, coolant and compressed-air circuits, industrial pumps, filtration units, cooling loops, machinery, hose assemblies and maintenance systems. The combination of detachable connections and double shutoff supports equipment servicing and fluid-line changes within the specified pressure, temperature and chemical-compatibility limits.
