Stainless Steel 316 Quick Release Couplings
Stainless Steel 316 Quick Release Couplings – Flat Face, ISO A & ISO B
Our Stainless Steel 316 Quick Release Couplings are engineered for fast, secure and leak-free connection and disconnection of hydraulic and fluid transfer systems. Designed for demanding Australian conditions, this range includes Flat Face (ISO 16028), ISO A (ISO 7241-1 Series A) and ISO B (ISO 7241-1 Series B) couplings, widely used across hydraulic, industrial, marine and high-pressure applications.
Manufactured from 316 stainless steel, these quick connect couplings provide excellent resistance to corrosion, saltwater, chemicals and washdown environments. They are commonly used as compatible replacement styles for coupling series from leading manufacturers such as Parker (FEM, FF, 6600 Series), Faster (FFH, NV, HNV), Eaton Aeroquip (FD Series), Stucchi (A Series, IR Series), Hansen (HA Series), CEJN, Holmbury, Ryco and Snap-Tite, subject to confirming size, pressure rating and compatibility.
Why Choose Stainless Steel 316 Quick Release Couplings?
- Fast Connection: Quick connect and disconnect without tools, reducing downtime.
- Corrosion Resistant: 316 stainless steel is ideal for marine, chemical and washdown environments.
- Leak Reduction: Flat face couplings minimise fluid loss and contamination.
- High Pressure Capability: Designed for demanding hydraulic systems.
- Wide Compatibility: Matches common ISO standards used across global equipment.
Common Applications
- Hydraulic systems and mobile plant equipment.
- Marine, offshore and saltwater environments.
- Mining, construction and agricultural machinery.
- Food processing, washdown and chemical systems.
- Oil, gas and fluid transfer applications.
Coupling Types Explained
- Flat Face (ISO 16028): Non-spill design that minimises fluid loss and contamination, ideal for environmentally sensitive and high-pressure systems.
- ISO A (ISO 7241-1 Series A): General-purpose hydraulic quick coupling with poppet valve design, widely used in agriculture and industry.
- ISO B (ISO 7241-1 Series B): Industrial interchange coupling commonly used in manufacturing, construction and fluid transfer systems.
Available Configurations
- Male Couplers (Plugs/Nipples): Connect into female couplers for quick engagement.
- Female Couplers (Sockets): Designed for secure locking and easy release mechanisms.
- Thread Options: Available in BSP, NPT, JIC, ORFS and Metric connections.
- Sizes: Multiple sizes available to suit hydraulic hose and system requirements.
Important Compatibility Notes
Flat face, ISO A and ISO B couplings are not interchangeable with each other unless specifically designed. Always confirm ISO standard, size, pressure rating, thread type and application requirements before use to ensure safe and correct operation.
Manufacturer names such as Parker, Faster, Eaton Aeroquip, Stucchi, Hansen, CEJN, Holmbury, Ryco and Snap-Tite are used for reference only to assist with identifying commonly used coupling styles. These products are not represented as genuine parts unless specified. Customers should confirm suitability in accordance with Australian Consumer Law.
Need Help Choosing the Right Quick Release Coupling?
Selecting the correct coupling is critical for performance and safety. Identify your ISO standard, thread type, flow requirements and pressure rating before purchasing. For hydraulic systems, always ensure compatibility with hoses, fittings and machinery specifications.
Welcome to Hydraulic Online — Australia’s Online Hydraulic Components Store
Hydraulic Online is an Australian-owned e-commerce business specialising in hydraulic components for agriculture, construction, mining, marine, transport, and industrial applications.
With over two decades of hands-on industry experience, we supply field-proven products that are built to perform in real working environments — not just to look good on a spec sheet.
What We Supply
Our range covers the full hydraulic system — from hoses and fittings through to motors, pumps, cylinders, valves, power packs, and accessories.
Whether you’re replacing a worn orbital motor, building a power pack, or just need a hose assembly made to a specific length, we have what you need in stock and ready to ship.
Who We Supply
We supply trade customers, farmers, equipment dealers, hire companies, plant operators, and DIY owners across Australia. Orders ship from warehouses in Queensland, Victoria, South Australia, and Western Australia — with same-day dispatch on orders placed before 12 noon AEST where stock is available.
Why Buy From Us
We are not a catalogue company. Every product we sell has been selected based on real-world performance feedback from our service workshop and our customers.
We carry products we stand behind, at prices that reflect our volume buying — not inflated margins.
