Precision Manufacturing & Assembly
The Turbo Kings AD-9 w/ Plug (K046157) air dryer is newly manufactured to OEM Bendix AD-9 standards and built to protect heavy-duty air systems from oil, moisture, and contamination. Each unit is pressure-tested to 150 PSI to ensure flawless purge-valve performance and total air-tight integrity under working load.
Every air dryer in this series is equipped with BRV high-temperature O-rings for long-term resistance to heat cycling and vibration, while all internal valves and pistons are lubricated with HP-870 synthetic high-temperature grease to ensure smooth function, corrosion resistance, and moisture isolation.
Designed with a pre-installed 12V heater plug, the K046157 prevents freezing during cold weather, maintaining reliable operation in all climates. Each housing is thoroughly cleaned, neutralized, and moisture-purged before sealing to deliver a clean, ready-to-install product.
What Makes Turbo Kings Air Dryers Different
Turbo Kings air dryers aren’t mass-imported units — they’re precision-assembled in-house and tested to the same specifications as the original Bendix AD-9. Each dryer undergoes multi-stage verification for purge timing, heater circuit continuity, and pressure regulation.
High-Temp BRV O-Rings – Resilient under extended thermal and vibration exposure
HP-870 Synthetic Grease – High-temperature lubricant for consistent valve function
OEM Bendix-Style Heater Plug (12V) – Ensures reliable purge operation in cold weather
Full 150 PSI Pressure Testing – Guarantees leak-free, purge-ready operation
Cleaned, Purged, and Neutralized Assembly – Moisture-free for immediate installation
Built by Turbo Kings – Locally assembled for superior quality control
Why Fleets and Owner-Operators Trust Turbo Kings
The AD-9 w/ Plug (K046157) is the preferred heavy-duty air dryer for fleet operators who demand OEM-level performance with improved longevity. It prevents costly issues like frozen purge valves, oil carry-over, and pressure lag by maintaining a clean, dry air supply throughout the braking and suspension systems.
Each unit is performance-verified under 135–150 PSI load, ensuring precise purge-valve cycling and governor communication. Built by Turbo Kings with verifiable test data, this air dryer guarantees uptime and reliability in both fleet and single-truck applications.
Delivered pre-lubed, pre-tested, and fully capped, the K046157 arrives ready for direct installation — no adjustments or prep required.
