ARB 160706SP Type K Air Locker Bonded Piston Seal Replacement

The ARB 160706SP is a genuine replacement Type K bonded piston seal designed specifically for ARB Air Locker differentials. This OEM-spec service part maintains the pneumatic integrity of the Air Locker system, ensuring the piston can build and hold the air pressure needed to engage the locking mechanism reliably.

The bonded piston seal sits inside the Air Locker differential carrier and is responsible for creating an airtight chamber around the actuating piston. When the seal wears or degrades, the system loses pressure, preventing the locker from engaging and often allowing air to escape through the diff breather. Replacing the bonded seal restores full locking function.

Key Features:

• Genuine ARB OEM replacement part — ensures proper fit and function
• Type K bonded seal design — rubber bonded to a rigid carrier for durability and consistent sealing
• Engineered to handle extreme climatic temperatures and demanding off-road conditions
• Critical component for ARB Air Locker differential rebuild and maintenance
• Sold individually

Refer to your specific ARB Air Locker model number (RD-series) and the ARB parts catalog to confirm this is the correct bonded seal type for your application before ordering.
