This ARB seal housing kit — size code 70/71 — restores the airtight seal that drives your Air Locker. The housing feeds compressed air to the locker's actuator, and its O-rings are the wear item that eventually leaks; renewing them brings back fast, dependable engagement.
Use it during a diff rebuild or when a locker starts to lock slowly or bleed down. Genuine ARB parts hold the correct bore and groove dimensions for a reliable seal.
