Overview
The ARB160227-2 is a replacement O-ring for the ARB Air Locker seal housing. It is meant to keep the air locker sealed and working properly.
The seal housing was refined over time to prevent leakage. These O-rings are replacement seal parts, so match them to your locker’s seal housing.
Key features
- Replacement O-ring for the Air Locker seal housing
- Designed to keep the air locker sealed and working properly
- Seal housing design described by ARB as improved to prevent leakage
- Fit depends on the locker’s seal housing, not on a vehicle model.
Signs of seal leakage
O-rings in a locker housing wear from heat, age and grit. Once the rubber flattens or cracks, the seal stops holding air or fluid, and the locker may engage weakly or leave oil on the housing. Leaks often appear first as a small wet spot at the seam, so a quick look after trail use can catch them early.
When the housing is open for other service, inspect every O-ring in it, not just the one that leaked. Seals that have seen the same heat and age tend to wear together. Use a grease that suits the seal material, keep sealing surfaces clean, and avoid nicks when refitting.
- Flattened or cracked rubber
- Nicks from careless reinstallation
- Debris trapped in the seal groove
