Description
Professional Safety Air Coupling
Engineered for demanding workshop environments where safety and performance are non-negotiable
Two-Stage Safety Release
Advanced safety mechanism prevents dangerous hose whip by venting compressed air in controlled stages before full disconnection. Protects operators during tool changes and system maintenance.
High-Flow Performance
Optimised 5mm nominal bore delivers 43 CFM at 100 PSI, ensuring pneumatic tools receive consistent air supply with minimal pressure loss. Engineered for professional-grade air delivery.
Industrial-Grade Construction
Precision-machined steel body withstands demanding workshop conditions. Rated to 14 bar (200 PSI) maximum working pressure with exceptional wear resistance and long service life.
Universal Compatibility
1/2" BSP male thread connection. Interchangeable with Rectus 19 Series, Kee 057 Series, Oetiker SC Series P, and Ludecke ESB systems for seamless integration into existing compressed air installations.
Applications
- Professional Workshops – Reliable air tool connection for automotive, fabrication, and maintenance facilities
- Industrial Environments – Heavy-duty pneumatic systems requiring consistent high-flow performance
- Garage & Workshop – Safe, efficient air delivery for impact wrenches, spray guns, and air-powered equipment
- Manufacturing – Production line pneumatic tool integration with safety-first design

Safety Features
Designed with operator protection as the primary consideration:
- Two-Stage Venting System – Controlled air release prevents sudden hose movement and operator injury
- Secure Locking Mechanism – Positive engagement ensures leak-free connection under pressure
- Wide Temperature Tolerance – Reliable operation from -40°C to +100°C in varied working conditions
- Pressure-Rated Construction – Tested to 200 PSI for dependable performance in high-demand applications
Why Choose This Safety Coupling?
In professional pneumatic systems, the coupling is a critical safety component—not just a connector. This 1/2" BSP male thread safety coupling combines robust steel construction with intelligent two-stage release technology to protect operators while maintaining the high-flow performance demanded by professional air tools.
The 5mm nominal bore and optimised internal geometry deliver 43 CFM at 100 PSI, ensuring impact wrenches, spray guns, and pneumatic equipment operate at peak efficiency. Unlike standard quick-release couplings, the two-stage safety mechanism vents compressed air in controlled stages, eliminating dangerous hose whip during disconnection.
Manufactured to exacting standards and compatible with industry-standard coupling systems including Rectus 19, Kee 057, and Oetiker SC Series P, this coupling integrates seamlessly into existing compressed air infrastructure. Rated to 14 bar (200 PSI) and tested across a -40°C to +100°C temperature range, it delivers consistent, reliable performance in the most demanding workshop environments.
