ISO B12 Coupling with 10mm Hose Tailpiece
Professional-Grade Pneumatic Quick Release Fitting
Technical Specification
- Standard: BS EN ISO 6150-2 (ISO B Series)
- Profile: B12 Coupling Body
- Connection: 10mm (3/8") Hose Tailpiece
- Material: Premium Brass Construction
- Working Pressure: Up to 10 bar (145 PSI)
- Thread Type: Barbed Hose Tail
Engineering Excellence
This ISO B12 coupling represents the industry standard for pneumatic quick-release connections across European workshops and manufacturing facilities. Precision-machined from high-grade brass, the coupling delivers reliable air-tight sealing and effortless one-handed operation—essential for high-tempo production environments.
The 10mm hose tailpiece features a multi-barb profile engineered to grip flexible pneumatic hose securely, preventing blow-off under pressure cycling. When paired with the corresponding ISO B12 plug, the coupling locks with an audible click and releases via a simple sleeve retraction, enabling rapid tool changes without depressurizing the entire system.
Why Workshop Professionals Choose ISO B12
🔧 Universal Compatibility
ISO 6150-2 compliance ensures interchangeability with all major pneumatic brands including PCL, Rectus, and Cejn.
⚡ Instant Connection
Push-to-connect design with automatic valve closure minimizes air loss during coupling and decoupling.
💪 Built to Last
Corrosion-resistant brass body withstands daily workshop use, chemical exposure, and temperature extremes.
🎯 Precision Fit
10mm tailpiece suits standard 8mm ID / 10mm OD pneumatic hose—the most common workshop air line size.
Typical Applications
- Air tool connection points on workshop reticulation systems
- Portable compressor hose assemblies for mobile service vans
- Pneumatic control circuits in automated machinery
- Garage forecourt tyre inflation equipment
- Paint spray booth air supply manifolds
- Industrial blow-gun and air-duster assemblies
Installation & Assembly
- Hose Preparation: Cut pneumatic hose square using a sharp blade. Ensure the bore is clean and free from debris.
- Fitting Assembly: Push the hose firmly onto the 10mm tailpiece until it seats against the coupling body shoulder.
- Securing: Install a hose clip or crimp ferrule over each barb to prevent pressure blow-off (recommended for systems above 6 bar).
- System Integration: Connect to a compatible ISO B12 plug (sold separately) and pressure-test before commissioning.
Technical Considerations
Flow Capacity: The B12 profile offers a nominal bore of 7.4mm, delivering approximately 1,200 litres/min free air at 6 bar—sufficient for most pneumatic tools up to 1/2" impact wrenches.
Pressure Drop: Expect minimal pressure loss (typically <0.2 bar) when using quality hose and correct assembly techniques. Avoid kinking or undersized hose to maintain optimal tool performance.
Maintenance: Periodically inspect O-rings and valve seats for wear. A drop of pneumatic tool oil on the coupling face extends service life and ensures smooth operation.
