This 6mm steel joiner is used to repair or extend the air line for your ARB Air Locker system. The plastic air lines used for diff locks can become brittle and are often routed in vulnerable locations underneath your 4x4. A snagged or broken line will cause an air leak, preventing your diff lock from engaging when you need it most. A failed air line leaves you without that crucial traction, which can be the difference between driving out of a tough spot and needing a recovery.
This is a universal part designed for ARB Air Locker systems. Please check your air line size to confirm compatibility. Please contact us if you require further assistance.
