Details summary
Test point (pressure test connection) for compressed air brake systems in trucks and trailers, ISO 3583. A pressure gauge connects to the M16x1.5 measuring thread without depressurising the system.

The test point is installed permanently at a measuring point of the compressed air system, for example on an air reservoir, a valve port, or before and after the load-sensing brake valve. Its internal valve opens only when a test hose or pressure gauge is screwed on, and closes when it is removed.

  • Brake pressure measurements during service and inspection
  • Adjusting the load-sensing brake valve
  • Air suspension pressure checks and troubleshooting

The measuring thread is M16x1.5 on all sizes. Choose the male thread to match the component port: M12x1.5, M16x1.5 or M22x1.5.
