Description
Bendix 109993 is a genuine Bendix service kit that replaces the turbo cut-off valve on Bendix AD-SP and AD-9 family air dryers. The turbo cut-off valve seals the air dryer’s purge line against turbo-boost back-pressure during engine operation, then opens for normal purge when the governor cuts out — a worn cut-off valve causes air-dryer leaks at the discharge port and accelerates desiccant contamination.

Confirm your air dryer model (AD-SP or AD-9) before ordering. Follow the Bendix service-data sheet for the air dryer when installing — torque values and orientation matter for proper cut-off function. Drain and inspect the supply tank after the repair.
