Dry break couplers are used on tank trucks and industrial fluid transfer systems to prevent drips and spills when connecting or disconnecting. The kit contains a nitrile rubber nose seal, an O-ring, and a cotter pin—the key wearable parts that ensure a tight seal at the coupler's front end. Replacing these parts restores leak-free performance and prevents product loss during fuel, chemical, or petroleum transfers.
