OPW CNG Accessories include a series of in-line CNG breakaways that are installed on fuel-dispensing hoses between the nozzle and dispenser and will separate when subjected to a designated pull force, such as in the event of a driveaway. CNG defueling nozzles are designed to safely depressurize vehicles and can be used to transfer fuel from one vehicle to another. CNG fueling hoses are specially designed for dispensing CNG.
