It is a critical service component used to maintain a tight, leak-free connection on petroleum tank trucks during the offloading process. This seal is a common wear item, and a damaged or aged O-ring is a primary cause of fuel drips or vapor leaks at the drop adapter collar. Replacing this seal restores the integrity of the API connection, ensuring safe and compliant fuel delivery.
