Inspection connector

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.

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.
