ISO B12 Coupling with 13mm Hose Tailpiece

Professional-grade quick-release pneumatic connector engineered for demanding workshop environments

Technical Excellence

This ISO B12 coupling represents the industry standard for compressed air systems across the UK and Europe. Precision-machined to ISO 6150 B-12 specifications, it delivers reliable, leak-free performance in pressures up to 15 bar (217 PSI), making it the preferred choice for professional workshops, mobile service vans, and industrial maintenance teams.

The integrated 13mm (1/2") hose tailpiece provides a secure, barbed connection that grips reinforced air hose firmly, eliminating the risk of blow-off under pressure. Each coupling is manufactured from corrosion-resistant materials with a hardened steel ball-bearing locking mechanism that ensures thousands of connect-disconnect cycles without degradation.

Key Specifications

• ✓Universal compatibility: Mates with all ISO B12 plugs and adaptors, ensuring seamless integration with existing pneumatic systems
• ✓Automatic shut-off valve: Prevents air loss when disconnected, maintaining system pressure and reducing compressor cycling
• ✓Secure barbed tailpiece: 13mm hose barb creates a mechanical grip that withstands vibration and pressure spikes
• ✓UK stock, fast dispatch: Available for immediate shipment from our UK warehouse for next-day delivery

Typical Applications

• Automotive workshops and tyre fitting centres

• Manufacturing and assembly line pneumatic tools

• Mobile service vans and field maintenance equipment

• Woodworking and carpentry air tool systems

• Industrial maintenance and facilities management

Installation & Compatibility

The 13mm barbed tailpiece is designed for use with standard 1/2" internal diameter reinforced air hose. For optimal performance and safety, secure the hose connection with a quality hose clamp or crimp ferrule rated for pneumatic service. The coupling body accepts any ISO B12 male plug, making it ideal for creating custom hose assemblies or replacing worn couplings on existing air lines.

This coupling is suitable for compressed air service only. Do not use with flammable gases, oxygen, or corrosive fluids. Always verify system pressure does not exceed the coupling's maximum working pressure rating.
