Installation Notes
Thread Preparation: Apply PTFE tape or thread sealant to male threads. Tighten to manufacturer's torque specifications to prevent leaks.
Compatibility: Ensure mating plug conforms to ISO 6150 B-12 standard. Not compatible with ARO 210, Orion, or other proprietary quick-connect systems.
Why Choose This Coupling?
In professional pneumatic systems, connection reliability directly impacts productivity. This ISO B12 coupling combines precision engineering with robust construction to deliver consistent performance across thousands of connect/disconnect cycles.
The R3/8 BSP thread size represents the optimal balance between flow capacity and compact design for most workshop air tools operating at 6-8 bar. The automatic shut-off valve eliminates wasteful air loss during tool changes, reducing compressor run time and energy costs.
Manufactured to exacting ISO 6150 standards, this coupling ensures universal interchangeability with ISO B12 plugs from any manufacturer, protecting your investment in pneumatic infrastructure.
