Precision Manufacturing & Assembly
The Turbo Kings AD-9 Air Dryer (8700017) is newly manufactured to OEM Bendix standards and designed to deliver reliable air-system protection for heavy-duty applications. Each unit is pressure-tested up to 150 PSI, ensuring a perfect seal and consistent purge-valve response across every operating cycle.
Every AD-9 dryer receives upgraded BRV high-temperature O-rings for extended service life under high thermal and vibration loads. Internal pistons and purge-valves are lubricated with HP-870 synthetic grease, a premium compound formulated for resistance against heat, carbon buildup, and moisture contamination.
Each housing is purged, neutralized, and moisture-free prior to final sealing. The result is a clean, ready-to-install dryer that restores OEM performance while delivering the long-term reliability fleets expect from Turbo Kings.
What Makes Turbo Kings Air Dryers Different
Turbo Kings AD-series air dryers are not mass-produced imports—they’re locally assembled, pressure-validated, and individually serialized for traceability. Every dryer is built under controlled conditions, ensuring uniform pressure response and moisture-separation performance.
Upgraded BRV O-Rings — High-temperature, oil-resistant sealing for long-term durability
HP-870 Synthetic Lubricant — Prevents galling and valve drag under continuous cycling
OEM Bendix Design Compatibility — Direct-fit replacement for AD-9 systems
Full 150 PSI Pressure Test — Verifies leak-free air-integrity and purge operation
Internal Moisture Purge & Neutralization — Protects against corrosion and freeze-ups
Built by Turbo Kings — Assembled in-house for consistent, verifiable quality
Why Fleets and Owner-Operators Trust Turbo Kings
The AD-9 (8700017) is the industry’s most recognized air-dryer format—and Turbo Kings elevates it through precision assembly and enhanced material selection. Fleets rely on it to keep brake systems, suspension controls, and DEF components dry, balanced, and responsive.
Each dryer undergoes a real-pressure validation at 135–150 PSI, simulating real-world air-system loads to confirm proper governor cycling and purge release. With factory-level assembly and superior component integrity, this dryer eliminates common field issues such as oil carry-over, slow purging, or moisture bleed-through that lead to corrosion and downtime.
Delivered pre-lubed, pressure-verified, and moisture-free, every Turbo Kings AD-9 unit arrives ready for direct installation and immediate service.
